The Insider Pick:

• 
  

  It's easy for your dog to get fleas, so you'll want to protect your pup with the best flea prevention products. Of all the flea treatment pills, sprays, shampoos, and collars out there, Frontline Plus is the best. It's easy to apply and offers a full 30 days of protection to kill both fleas and ticks.

  
  

You have probably heard the saying that where there is one flea, there are likely hundreds or thousands more. It doesn’t take long for a few fleas to multiply into a major and fast-spreading infestation. Though fleas may not be quite as dangerous as ticks when it comes to transmitting diseases, your dog could still develop an allergic reaction to flea bites and an infestation could cause significant itching, irritation, and even hair loss. Luckily, there are many flea control and protection products on the market that are specifically designed to protect your dog against these pesky pests.

When it comes to flea control products, the options are nearly limitless, and there are many different types to consider. Fortunately for you, we’ve done the hard work in scouring the reviews to bring you our top picks for the five best flea control products for dogs. Below you will find our choices for the best flea control product overall as well as the best options for flea shampoos, sprays, collars, and tablets.

Although Frontline Plus is our top pick for flea control products, for various reasons laid out in the slides below, you should also consider the Adams Plus Flea & Tick Shampoo with Precor, the Vet’s Best Natural Flea and Tick Spray, the Seresto Flea and Tick Collar, and the Novartis Capstar Flea Tablets.

The best flea control product overall

Frontline

Why you'll love it: Frontline Plus is effective at killing both fleas and ticks in all life stages and it's very easy to use.

While there are many different forms of flea control for dogs, topical flea treatments tend to be the most fast-acting and long-lasting products on the market. These treatments typically come in liquid form and need to be applied directly to the dog’s skin once a month for maximum protection. Our top pick for the best flea control product for dogs is Frontline Plus because it kills both fleas and ticks in all life stages and protects against re-infestation for a full 30 days.

Frontline Plus is made with two powerful active ingredients – fipronil and s-methoprene – which work together to kill fleas and ticks in all life stages, including eggs and larvae. This product comes in several formulas for dogs of different sizes and it offers continuous protection for 30 days. Available in an easy-to-use, waterproof formula, Frontline Plus is one of the most comprehensive and effective topical flea control products on the market.

Entirely Pets names Frontline Plus one of the top ten flea treatments overall, noting that the formula’s dual active ingredients provide comprehensive protection against fleas in all life stages. With more than 1,600 reviews on Amazon, Frontline Plus has a consistent 4-star rating. DogFood notes that Frontline Plus is the top-selling and top veterinarian-recommended flea product on the market, plus it is highly effective against all species of ticks.

Though Frontline Plus may be a little more expensive than other topical flea preventives on the market, it is generally considered to be one of the safest options and it is by far one of the most effective. An in-depth review from Top Dog Tips confirms all of these points.

Pros: Dual active ingredients for maximum efficacy, kills both fleas and ticks in all life stages, provides a full 30 days of protection, waterproof, easy-to-use 3-step application process, available in multiple formulas for dogs of different sizes, safe for pregnant and nursing dogs

Cons: More expensive than other topical preventives, not recommended for dogs and puppies under 5 pounds or less than 8 weeks of age, bathing within 24 hours of application may wash away some of the product, may not prevent ticks from attaching (but will still kill them)

The best flea shampoo for dogs

Adams

Why you'll love it: Adams Plus Flea & Tick Shampoo with Precor kills fleas in all life stages and offers a full 28 days of protection.

If you have already found fleas on your dog, you may want to give him a nice bath with a flea shampoo. Flea shampoos are a type of medicated shampoo that can help to kill fleas and cleanse your dog’s coat. Keep in mind that some flea shampoos only kill adult fleas while others kill eggs and larvae as well. Our top pick for a dog flea shampoo that kills fleas in all life stages and provides a full 28 days of flea prevention is Adams Plus Flea & Tick Shampoo with Precor.

Flea shampoos are made with various active ingredients but the two main types are pyrethroids and pyrethins. Both are powerful insecticides, but pyrethrins are natural while pyrethroids are synthetic. Adams Plus Flea & Tick Shampoo with Precor contains natural pyrethrins to kill fleas, ticks, eggs, larvae, and lice upon contact. Meanwhile, Precor, an insect growth regulator, prevents eggs from developing into biting adults. This formula also contains natural ingredients like aloe, oatmeal, and coconut extract to soothe your dog’s dry and irritated skin.

Totally Goldens names this flea shampoo its top pick, noting that while it may have a somewhat unpleasant odor, it lathers easily and works to remove dandruff and scales while also cleansing and softening your dog’s coat. This product receives an A+ rating from Peanut Paws and Ready Set Dogs praises the shampoo for killing fleas in all life stages for long-lasting protection.

Adams Plus Flea & Tick Shampoo with Precor has more than 500 reviews on Amazon with a solid 4-star rating. Some users found the product to be ineffective, but multiple reviews state that it is necessary to lather the product well and work it into the dog’s coat for the best results.

Pros: Made with natural pyrethrins as the active ingredient, kills fleas in all life stages, protects against ticks and lice, contains an insect growth regulator for 28 days of flea prevention, contains soothing natural ingredients, removes dandruff and scales while cleansing coat, safe for puppies and adults

Cons: May not be recommended for puppies under 8 weeks of age, has a somewhat strong odor, must be worked into a thick lather for best penetration

The best flea spray for dogs

Vet's Best

Why you'll love it: The Vet’s Best Natural Flea and Tick Spray provides all-over protection against adult fleas, flea eggs, and ticks in a non-staining, pleasant-smelling formula.

If you’re looking for an all-in-one solution for adult fleas and their eggs, a flea spray might be the best option. Not only can you use a flea spray on your dog, but you can also use it on his bedding and other household surfaces. Many flea sprays offer limited efficacy or they are made with dangerous chemicals. Our top pick for a safe and effective flea spray for dogs is the Vet’s Best Natural Flea and Tick Spray.

While many flea sprays are made with toxic chemicals, Vet’s Best Natural Flea and Tick Spraycontains natural key ingredients like peppermint oil and clove extract. In a non-staining formula, this spray kills both adult fleas and their eggs, plus it protects against ticks and repels mosquitos. Simply spray the formula directly onto your dog’s coat until damp, and then massage it in until it reaches the skin. Repeat as necessary.

Named the number one flea and tick spray for dogs by Heavy, Vet’s Best Natural Flea and Tick Spray kills fleas and their eggs and kills ticks on contact. It also repels mosquitos to some degree. Top Dog Tips notes that this spray is safer than most flea treatments and that it can also be used to treat carpets, furniture, and bedding. It is also much more affordable than many flea preventives on the market.

With nearly 4,000 reviews on Amazon, Vet’s Best Natural Flea and Tick Spray has a solid 4-star rating. Customers love the easy spray-on formula, though some users report needing multiple applications to achieve the desired effect. It is entirely possible that they didn’t massage the spray into the dog’s coat, as directed on the bottle.

Pros: Made with natural active ingredients, safe for use around pets and children, non-staining formula, easy to apply, can be used outdoors and on home surfaces, kills adult fleas and eggs and ticks, repels mosquitos, manufactured in the USA, pleasant scent

Cons: Not recommended for puppies under 12 weeks of age, needs to be massaged into the coat for maximum efficacy, may cause irritation or allergic reaction in humans with prolonged contact, may induce sensitivity in some dogs, not recommended for cats

The best flea collar for dogs

The best flea collar for dogsSeresto

Why you'll love it: The Seresto Flea and Tick Collar from Bayer offers eight months of protection against both fleas and ticks without the hassle of monthly application.

If you’re looking for long-lasting protection against fleas that you don’t have to reapply month after month, a flea collar might be the best option for your dog. Though there are many flea collars on the market, the Seresto Flea and Tick Collar from Bayer is far and away the best option. With more than 8,000 reviews on Amazon and a solid 4-star rating, this is our top choice for dog flea collars.

The Seresto Flea and Tick Collar offers a full eight months of protection from both fleas and ticks. Made from a unique polymer matrix with two powerful active ingredients, this odorless flea collar kills fleas and ticks on contact — they don’t have to bite your dog for it to work. This collar is non-greasy and easy to use, plus it has a two-way release safety feature in case your dog gets it caught on something. It is also water resistant so it can be worn through monthly bathing and occasional swimming.

Whereas most flea collars deposit low-dose insecticides into your dog’s skin to poison fleas as they bite, the Seresto Flea and Tick Collar utilizes a unique delivery system that distributes the active ingredients in low concentrations over your dog’s hair and skin. As the active ingredients wear off, the collar continuously replenishes them for hassle-free, long-lasting protection. No other flea collar works in quite the same way or offers the same degree of protection.

A review from HerePup names the Seresto Flea and Tick Collar the best flea and tick collar for small dogs and Top Dog Tips gives it the highest A+ rating. Heavy names this collar among its top five picks for flea prevention in general, commenting that it is very similar in price to a six-month course of topical flea preventive but offers an extra two months of protection. No other flea collar receives such consistently high ratings or as many positive user reviews.

Pros: Offers a full eight months of protection from both fleas and ticks, insects do not have to bite for the collar to work, odorless and non-greasy, two-way release safety feature, comfortable and easy to wear, water-resistant for monthly bathing and occasional swimming

Cons: Not recommended for puppies under seven weeks of age, not recommended for dogs under 18 pounds, should not be combined with other forms of flea prevention, effective duration may lower to five months if worn frequently during swimming

The best flea pills for dogs

Capstar

Why you'll love them: To stop an existing flea infestation in its tracks, Novartis Capstar Flea Tablets are our top choice for oral flea medications.

If you don’t like the idea of using a topical flea preventive and you aren’t sure your dog will tolerate a flea collar, there is still another option – oral medications or flea pills. Flea pills can kill adult fleas in as little as 30 minutes, making them a great solution for dogs with flea allergies. Our top pick for oral flea medications is Novartis Capstar Tablets. Available in two formulas for dogs under and over 25 pounds, these flea pills are fast-acting and highly effective.

Safe for use as a daily treatment, Novartis Capstar Flea Tablets start killing adult fleas within 30 minutes and will kill more than 90 percent of adult fleas within 4 hours. These tablets contain the active ingredient nitenpyram, an insecticide that interferes with nerve transmission in fleas but has no adverse effect on dogs or cats. This treatment is available without a prescription and is approved for dogs over 2 pounds in body weight and over 4 weeks of age.

Novartis Capstar Flea Tablets are frequently compared to Comfortis Flea Tablets, a prescription flea medication. Both medications begin killing adult fleas in as little as 30 minutes but Novartis Capstar Flea Tablets do not require a prescription for purchase. A review from Consumer Search also notes that Comfortis Flea Tablets are much more likely to cause negative side effects.

Novartis Capstar Flea Tablets do not offer month-long protection like their competition, but they can be given in repeated daily doses to manage severe infestations.

With more than 4,500 customer reviews on Amazon, Novartis Capstar Flea Tablets have a solid 4-star rating. Top Dog Tips names these tablets its top pick for oral flea medications, noting that they are safe for use on a daily basis and that they are the most effective when combined with thorough household cleaning to remove eggs and larvae.

Pros: Kills existing adult fleas in as little as 30 minutes, does not require a prescription to purchase, available in two formulas for dogs of different sizes, can be given as a daily dose as needed, safe for pregnant and lactating dogs, can also be used for cats

Cons: Dogs over 25 pounds may need a higher dose, may not kill flea eggs or larvae, not recommended for puppies under 4 weeks of age or under 2 pounds, may require repeated treatment for optimal results, may cause negative reactions or side effects in some dogs

Best Flea Control For Dogs

[caption id="attachment_455" align="aligncenter" width="560"] best-flea-control-for-dogs[/caption]

Topical and oral flea control treatments are most effective

Fleas are more than an annoyance -- they can affect the health of their host dog or cat. A flea's saliva could trigger allergies, and the itching and scratching that ensues can lead to a more serious skin infection. Infected fleas can also transmit tapeworms and bacteria -- including bacteria that are harmful to humans. A large enough number of fleas can even cause life-threatening blood loss.

Unfortunately, fleas are not a problem that will go away on its own. In fact, ignoring a few fleas can quickly lead to an infestation. Female fleas can lay up to 50 eggs a day, many of which fall off and land in carpets, bedding and furniture. Once the larvae hatch, they remain inactive in cocoons for weeks or even months. Unsuspecting pet owners might think the problem is resolved after killing the adult fleas, but the life cycle will repeat weeks later unless eggs and larvae are prevented from maturing into adult fleas. Experts say the most effective way to keep fleas off a dog or cat is with a topical or oral medication.

Types of Flea Control

Topical Treatments

Flea Collars

Oral Medications

Topical Treatments

Also known as spot-on products, topical treatments are squeezed out of a tube and applied to the pet's neck or back. One advantage of these products is that they generally contain insect growth regulators (IGRs), which prevent eggs from hatching and larvae from maturing into adult fleas. This means that a single application can completely eliminate fleas for up to a month. However, these products have drawbacks as well. Although they're generally safe for pets if applied correctly, they can irritate the skin or eyes of humans; should you come in contact with the product, it must be rinsed off promptly. Once applied, the product may take several hours to dry. During this time, it may rinse off in water, and the residue may transfer to other pets, furniture or humans. Moreover, some pet owners find the smell or feel of the spot-on treatments unpleasant.

Flea Collars

Until recently, experts have said that flea collars are generally ineffective; some are toxic to pets and people as well. There is one exception, however, Seresto, which uses the same active ingredient as a well-rated topical treatment, Advantage, but in a slow-release formulation. Seresto also has a tick killing ingredient. Seresto is pricey, so other options are more cost effective if you pet is indoors most or all of the time, but for pets that spend lots of time out of doors, it can make sense. No other flea collar receives much, if any, positive feedback from pet experts.

Oral Medications

Flea control medications pose no risk to humans, and they don't leave any messy residue. Oral flea treatments tend to kill adult fleas very quickly, but most of them don't contain an IGR to deal with the eggs and larvae. This means that pet owners must either combine the tablet with a second treatment that contains an IGR, such as a spot-on product, or keep repeating the dose until no new fleas are hatching. Another problem is getting a pet to take the pill. While some users say their pets will gobble them happily if they're tucked inside a treat, others -- especially cat owners -- find it very difficult to get them down their pets' throats. Also, some oral medications are available only with a prescription from a vet.

Do other remedies work?

Flea shampoos can provide immediate relief by killing adult fleas on the pet, but they don't leave enough residue behind to kill new fleas as they hatch. As for flea dips, bombs, powders and sprays, many of them contain chemicals called pyrethroids, such as permethrin. Experts warn that these chemicals are highly toxic, especially to cats. Some vets say that products containing permethrin can be safe if you only have dogs in your household, but all warn to not use such products on cats or even on dogs if one is likely to come in contact with a cat. Permethrin comes in for the sternest cautions, but some experts also warn against the use of other pyrethroids as well.

Natural remedies are more controversial. We see lots of recommendations for them around the Internet, and receive plenty of questions about them from our readers. However, there's little scientific evidence that they are effective in most cases. In a recent blog post, Nancy Kearns of The Whole Dog Journal says that she's "never had much luck with the plethora of natural remedies out there." And some natural remedies are rated to be just as toxic according the GreenPaws Flea and Tick Products Directory published by the Natural Resources Defense Council, and in some cases more so, than many of the topical and oral treatments recommended in this report

"Flea Product Comparison"

Because comparative, unbiased testing is hard to find when it comes to flea control products, we looked first at feedback from veterinarians and other recognized pet experts who have extensive experience with the options, their relative effectiveness, and their safety. One scientific journal, Parasites & Vectors, provides testing based information and is also helpful, but is written for a professional audience, rather than pet owners, and some of the research is paid for by flea control makers, so though peer-reviewed, bias can't be ruled out. The Natural Resources Defense Council provides feedback on relative safety of many products, but doesn't weigh in at all on effectiveness.

The rest of the feedback is supplied by pet owners. We scoured thousands of user reviews at sites like Amazon.com, Petco.com, and 1800PetMeds.com to find flea control treatments that pet owners say are effective and safe. We looked at both positive and negative feedback -- assessing the latter to weed out instances where supplier issues or incorrect usage might be factors -- to find those options that work successfully to rid pets of fleas and, in some instances, other parasites. The result of that research is our recommendation for the best topical and oral flea control products.

Advantage II stands out for safety and effectiveness

The top two topical flea treatments for both dogs and cats are Advantage II and Frontline Plus. They use different active ingredients, imidacloprid and fipronil, respectively, to eradicate infestations. The two insecticides work differently, but experts say that when used correctly, they are both safe and effective.

Both products receive mostly positive reviews from veterinarians and pet owners, but we found somewhat stronger recommendations for Advantage II. Cat owners, in particular, tend to give Advantage II for Cats

 (Est. $45 and up for a four-month supply) high marks for its effectiveness, safety and ease of use. While it does not work for every cat, it's more consistently effective than any other topical treatment. Most owners also find it easy to apply and are not bothered by the odor.

Advantage II is a reformulated version of an older product called Advantage, first released in 1996, which killed only adult fleas. The current version includes an insect growth regulator (IGR) to kill flea eggs and larvae as well. Both the original Advantage and Advantage II get positive reviews from veterinarians, including those who specialize in cat care. Vets at the All Feline Hospital in Lincoln, Neb., describe Advantage II as "very safe and effective on cats." However, reviews from cat owners indicate that in very rare cases, cats may have dangerous reactions to this treatment, so it's probably wise to consult a vet before use.

Advantage II for Dogs

 (Est. $40 and up for a four-month supply) is sold in several different dosages, for small, medium, large and extra-large dogs; as you might expect, versions for larger dogs cost a little more than those for smaller ones. Dog owners are not quite as enthusiastic about Advantage II as cat owners. Although most owners find it effective, dog owners were more likely than cat owners to complain that Advantage II either didn't work or stopped working before the one-month treatment period was up. Veterinarian dermatologist Jon Plant, writing at the Itchy Dog Blog, notes a study, albeit in cats, that shows some drop in effectiveness toward the end of a month. He adds that "the Advantage line of products are generally very effective for flea control in most situations, when used as directed (monthly)."

Bayer (the maker of Advantage II) also offers Advantage Multi (Est. $85 for a 6 month supply). Advantage Multi, offered by prescription only and in formulations for dogs and cats, adds additional protections against hookworms, round worms and other parasites (depending on the species). However, it is not an all life cycle flea killer and is only effective on adult fleas, not flea eggs and larvae. The cat version is the only product that's also FDA approved for use on ferrets (minimum weight of 2 pounds). One disadvantage to products in the Advantage line is that they don't protect against ticks. If that's a concern, a different product could be a better choice.

Frontline Plus, like Advantage II, is a reformulated version of an older product. The original Frontline killed adult fleas, as well as lice and ticks. The new version, Frontline Plus, also contains an IGR to kill fleas at every stage of their life cycle. It continues to protect against ticks and chewing lice as well, something that Advantage II can't do. Frontline Plus for Cats

 (Est. $40 for a three month supply) comes in a single formulation. Frontline Plus for Dogs

 (Est. $35 and up for a three month supply), like Advantage II for Dogs, comes in four dosage versions for dogs of different sizes.

Frontline Plus gets high marks for safety from both vets and pet owners. Frontline works by over-stimulating a flea's nervous system, making them hyperactive before they die. That can make it look like your pet's flea infestation is actually getting worse as fleas that were previously unseen rise to the top of its coat, and that results in some negative feedback in user reviews, but vets have few reservations. Dr. Plant notes that Frontline Plus is "100% effective at 12 and 24 hours from 1 day to 28 days post treatment."

There have been some reports, such as this article in The New York Times, indicating that, while fleas in a few parts of the country have become more resistant to fipronil (the active ingredient in Frontline), it and other treatments are still largely still effective in most regions. That's echoed in comments by Dr. Thomas B. McMillen at the Mercy Animal Hospital in Cranston, R.I., who says "There have apparently been some resistance problems in Florida, but there is no evidence of that around here." In a study published in Parasites & Vectors, a scientific journal, researchers Tad Coles and Michael Dryden find that reports of resistance to flea treatments is more likely to be caused by improper or insufficient application rather than resistance to the product by the fleas or other pests themselves.

ConsumerReports.org notes that, because the patent for fipronil has expired, generic versions of Frontline Plus are now available. Examples include Pet Armor Plus for Dogs

 (Est. $16 and up for a three month supply) and Sentry Fiproguard Plus for Dogs

 (Est. $15 and up for a three month supply). Formulations for cats are also available, as are generic versions of the original Frontline, designed to kill adult fleas but not eggs or larvae.

Experts do sound some cautions, however. While the active ingredients are the same, inactive ingredients can differ. ConsumerReports.org says that the least expensive generic substitutes can have lower dosages, requiring you to treat more often. The Whole Dog Journal specifically recommends against using low-budget spot on treatments as they can be more toxic and less effective than those "made by the most reputable and responsible manufacturers." Still, some vets and other experts consider generic versions of Frontline to be a reasonable alternative where budgets are a concern. If you are considering a generic version of Frontline or Frontline Plus, the best guidance would be to ask your vet. Finally, choose your vendor wisely as counterfeit versions of Frontline Plus have also been reported.

For dog owners who want to control both fleas and ticks, another option is K9 Advantix II

 (Est. $45 and up for a 4-month supply). Made by the same company that makes Advantage II, K9 Advantix II contains the same ingredients, plus an additional ingredient called permethrin that kills ticks and mosquitoes. Permethrin is highly toxic to cats, so K9 Advantix II is for use on dogs only. While permethrin is not generally considered harmful to dogs, reviews from dog owners suggest that K9 Advantix II is more likely to cause side effects than either Advantage II or Frontline Plus. Skin irritation is the most common problem, but a few owners describe more serious reactions. Still, K9 Advantix II appears to be an effective product for treating both fleas and ticks in dogs.

A flea collar to consider

In general, flea collars get a thumbs down from experts as being both ineffective and often toxic. One that breaks from the pack, however, is the Seresto Flea and Tick Collar

 (Est. $55). This is another product that uses the same active ingredient as Advantage, and is made by the same company, but in a gradual release format that keeps pets pest free for eight months. There's no IGR, but one's not needed as the active ingredient is constantly killing fleas as they emerge. Seresto collars also have a tick-killing component, flumethrin, so they are a great choice for animals that spend a lot of time outdoors.

Vet feedback thus far has been largely positive, and the Seresto flea collar receives lots of user feedback at sites like Amazon.com, most of which has been very good. In a blog post, Nancy Kearns of The Whole Dog Journal reports using Seresto to keep her dogs flea free after an outbreak had been eradicated. "So far, so good; I haven't spotted any fleas, and you can believe I've been looking," she writes. Dr. Plant notes that it kills 100 percent of existing fleas on dogs within 24 hours, and re-infesting fleas in two hours. It's also 98 percent effective on cats within 6 hours. One caution that he shares is that while the collar is rated to be effective for eight months, frequent swimming or bathing can reduce that duration.

Adverse reactions seem to be relatively rare. However, since this flea collar uses the same active ingredient as Advantage, if your pet has not done well with Advantage, Seresto also won't be a good choice. Some complaints are seen about the cost, a concern that Kearns echoes as well, especially for those with multiple pets, but keep in mind that a single collar is the equivalent of eight monthly does of Advantage. Versions are available for both dogs and cats.

What Flea Treatment Is the Best for My Dog?

Fleas may be small in size, but they can cause your dog to experience excessive itching, hot spots, and skin infections. In general, these conditions can be prevented by using a flea control preventative. Don't let your dog suffer from an uncomfortable flea infestation. Help remove fleas on your dog and prevent future infestations by using the variety of available flea control products such as those listed below.

Oral tablets & chews for flea control

Oral flea treatments such as Comfortis are quick and effective. The medication travels through your dog's bloodstream and to the skin's surface, helping to kill biting fleas. Newer combination pill treatments such as Sentinel and Trifexis also prevent heartworm disease and other intestinal parasites like roundworms, hookworms and whipworms. See product label for details.

Bravecto

Comfortis

Trifexis

Sentinel

NexGard Chewables

Sentinel Spectrum

Topical flea solutions

Topical flea control for dogs is most popular in liquid drop form. These products can treat existing infestations and help prevent future outbreaks. Apply the product directly onto your dog's skin, between the shoulder blades, unless otherwise noted on the product packaging. For small breeds, Flea5X Plus for Dogs is recommended and for large dogs, we recommend Frontline Plus or K9 Advantix II. All are waterproof.

Simply spritz your dog's coat all over, from the neck down and along the tail. For the head and eye area, spray on a gloved hand or washcloth and rub gently into your dog's hair, being careful not to get any of the product in your dog's eyes or mouth.

How do Flea Collars Work?

Fleas are uncomfortable and potentially harmful bugs that latch on to your dog’s skin and feed on her blood. A flea infestation will be miserable for your dog, and excessive scratching and licking can cause skin infections. Flea collars are a preventative measure that can protect your pup from both fleas and ticks.

There are two different types of flea collars available. One variety emits a gas that is toxic to fleas, but this type of collar usually only kills fleas in the nearby vicinity. Fleas around the base of the tail can often survive. This type of collar is best used inside of a vacuum bag instead to kill any fleas that you suck up while cleaning.

The other type of collar has a medication that is absorbed into the fat layer under a dog’s skin. When a flea bites, it is poisoned. This type of collar is much more effective at preventing a flea infestation.

Flea collars don’t necessarily need to be worn at all times. If you’re planning to take your dog out to a thicket where there might be fleas or ticks, you can have her wear a flea collar for just that day. Make sure to remove it when your pup no longer needs to wear it.

Don’t put a flea collar on your dog if she’s already getting another form of treatment such as an oral medication or a topical ointment. Overmedicating your pup could result in an expensive trip to the vet. The neurotoxins used in flea treatments can build up in your pooch’s body and create health problems.

Flea collars are designed just for pets, so be careful when handling them. Human skin is sensitive and not protected by a layer of fur, so the toxins can easily get on your hands. This could be harmful if you accidentally touch your eyes or pick something up to eat. Always wash your hands after touching your pup’s flea collar.

Other pets such as cats can also be harmed by a flea collar designed for dogs. If you have any other pets that need a flea treatment, get them medication that is specifically geared towards their species.

What to Look for in a Flea Collar

One of the most important things to consider when looking at flea collars is your dog’s size. Your pup should not be able to reach down and gnaw on her flea collar since ingesting the toxins inside can be dangerous for her health.

Flea collars are designed to be safe for a dog’s skin, but not necessarily her digestive system. Try to find a flea collar that is not big enough for your dog to reach, but not so small that it irritates the skin around her neck.

One of the best things about flea collars is that they can last for months, unlike most topical medications. Using a flea collar may be more convenient to some people that remembering to apply an ointment every thirty days. Make sure that you don’t use the collar longer than advised by the manufacturer or it could lose its effectiveness.

Safety Precautions

All flea collars use toxic chemicals, or insecticides, to get rid of fleas. In small enough doses, these insecticides are safe for your pooch but deadly to those pesky fleas. Always check the active ingredients in your dog’s flea collar since some of these chemicals are safer or more effective than others.

Deltamethrin, a synthetic pyrethroid, is one of the safest insecticides out there. It has minimal effects on both humans and our furry friends, but it’s not the only acceptable choice.

Pyriproxifen is another safe insecticide that targets eggs and larvae instead of adult fleas. It makes them unable to reproduce, so they die within a generation. Propoxur destroys the nervous system of fleas to kill them, but is dangerous for humans. A collar containing propoxur should be handled with care.

Tetrachlorvinphos (TCVP) should be avoided whenever possible. Although it does kill fleas, it is harmful to both you and your pets. TCVP is also a human carcinogen. Children are especially vulnerable to the effects of TCVP. Some collars still use this insecticide, but there are plenty on the market that use safer chemicals.

A high quality, comfortable flea collar can be a lifesaver for both you and you dog. Your pup won’t be in pain, and you won’t have to worry about fleas getting tracked into your house. Flea collars are a safe, effective preventative measure in both the long and short term.

Which One Should you Buy? Here's My Two Cents...

Collar	Quality	Our Rating
Seresto Flea & Tick Collar for Small Dogs	A

Virbac Preventic Tick Collar for Dogs	A
UltraGuard Flea and Tick Collar for Large Dogs	B
LSD Anti-Flea, Tick & Mosquito Dog Collar	B

Seresto Flea and Tick Collar for Small Dogs

The Seresto collar for small dogs is one of the longest lasting on the market, and can be effective for up to 8 months. This collar kills both fleas and ticks, although it is more effective at eliminating flea problems.

It is built to be sturdy and is even waterproof, which allows you to keep it on during bath time. For safety, there is a quick release mechanism present that lets your pet escape if the collar gets caught on anything.

As with some other flea collars, certain dogs are susceptible to damage from the toxins released. The Seresto flea collar has been known to cause health problems such a seizures in some dogs, and should be used with caution if you have an elderly or sensitive pup.

4 in 1 Dog Flea and Tick Collar by Facilla

This is a nylon collar that is most suitable for a small or medium dog. It is adjustable, ranging from 21 to 30 centimeters in diameter.

It is a simple collar and has an easy clip attachment for quick removal. The nylon itself is tough, but is not well reinforced. This collar can’t stand up to too much abuse.

This model works by continuously emitting a toxic gas that kills adult fleas in the near vicinity. It works for up to four months, which is long enough for eggs and larvae to die off. This product also kills lice, ticks, mites and mosquitos. It is not waterproof, so be sure to remove it during baths or swimming.

Virbac Preventic Tick Collar

This is not exactly a flea collar, but is designed to specifically target ticks. It detaches and kills them with a toxic chemical and starts working within 24 hours. The Preventic collar is effective for up to 3 months.

It is great at getting rid of tick infestations, but does not work as well on fleas. If you want to protect your pup against both, you should use this collar in combination with a topical flea treatment.

Some dogs can experience a reaction to the chemical in this collar. If there is any skin irritation or changes in behavior such as lethargy, be sure to take the collar off and contact your vet immediately.

Hartz Ultraguard Flea and Tick Large Dog Collar

This collar is an ideal size for a large dog with a neck up to 26 inches and is built to be durable.

This collar lasts for up to 5 months and is water resistant to make bath time easier. It even comes with a fresh scent, which is a nice change from some of the smellier flea collars.

Hartz collars are effective at removing fleas and ticks, but contain TCVP, which is a carcinogen for humans and potentially dangerous for household pets. If you use this model of collar, be extra careful when handling it and keep it away from children.

LSD Pet Remedy Neck Collar

The LSD pet collar kills multiple pests, including fleas, ticks and mosquitoes. It starts working within 24 hours and lasts for up to 4 months.

It is constructed of thick, durable nylon to withstand wear and tear while still being comfortable for your pup. The buckle is easy to clip on and off for quick removal.

The LSD pet collar is not waterproof, so it should be taken off during baths. It is also not as robust as some other flea collars on the market. Even though this model is made of strong nylon, the LSD collar is susceptible to fraying and breaking.

We know that flea and tick prevention for dogs is one of the essentials for canine's health because fleas and ticks carry a number of very serious illnesses. Mild cases will make a dog lethargic and nauseous, but severe cases could cause him a lot of pain or even be fatal. Making sure your dog is wearing one of the best flea collars for dogs is vital to his overall health and well-being.

There are thousands of flea and tick species, but the most common problem causer is the cat flea. Cat fleas will set up a home on the dog, and lay eggs to continue infestation long after the original flea is gone. This is why preventing fleas and ticks is much more vital than trying to get rid of them after your dog has been infested.

Several studies have showed that the use of the best flea collars for dogs (as well as tick collars for dogs) are one of the most effective ways to fight these parasites on dogs. Below, I will take a closer look at the specific types of best flea collars for dogs and their effectiveness according to most recent research.

In this article, I also want to discuss the importance of using dog flea collars, what other type of flea prevention for dogs there is, what flea and tick treatment solutions work best, and review top best flea collars for dogs including these five:

Why use dog flea collars and how effective are they?

The key of using dog flea collars is prevention of ticks and fleas on the dog. While they do work as treatments on already infested dogs (as indicated by below studies), it's a good idea to protect your dog from fleas and ticks in the first place, and here's why.

Without getting into too much detail, it's already established that fleas are dangerous for dogs for a number of reasons, and so are ticks. They spread diseases and pose fatal danger to pets. Vets agree that it's important to prevent fleas and ticks on the dog in the first place, but if that failed, then you must focus on breaking the flea's cycle ASAP:

“The best way to control fleas is to break the cycle. More fleas lay more eggs. The best treatment either kills the adults or kills one of the juvenile stages,” says Dr. Alison Diesel, DVM (source)

So do these best flea and tick collars for dogs work at breaking the cycle? 

Yes, most of the top rated tick and flea collars for dogs work, and they have been studied extensively to assess the success rate of these collars. Let's take a look at some studies.

For example, dog flea collars with imidacloprid/flumethrin will reduce flea count by 95%and tick count by 90% during a period of 7-8 months (1). Dog flea collars with deltamethrin have been shown the effectiveness of 85% to 97% (2). Propoxur injected dog flea collars were effective at about 80% to 90% range (3). Most flea collars for dogs will start working at about 48 hour mark (4).

As you can see, there are several types of best dog flea collars, but the effectiveness is approximately the same, going around 80% to 95% range for all of them. To pick the best tick and flea collar for your dog, you should have a discussion with your veterinarian first.

There are several factors that will matter in deciding which is the best dog flea collar for your specific animal. For example, your dog's breed (read: fur) will matter, your dog's behavior will matter, and it also matters what region you're based in. Some areas have a larger tick and/or flea population than others, mostly depending on the climate.

Other ways to fight fleas and ticks on the dog

In this article, I will mostly focus on discussing and reviewing the best dog flea collars and how they work. However, because flea and tick infestation on dogs is so common, there are also other ways to fight these parasites or prevent them in the first place.

Here are a few common alternatives (or additions) to dog flea collars:

• Dog flea pills – another very effective solution that's been proven to work.


• Dog flea shampoo – a good way to supplement other flea and tick treatments.


• Homemade flea/tick solutions – there are tons of natural, homemade flea and ticks solutions that also work, but research shows that they aren't as effective.

Our editor Samantha has also taken a thorough look at the three most popular dog flea and tick prevention, and have done a comparison/test of the best flea treatments here.

Your veterinarian will be able to recommend the best dog flea and tick treatment and prevention for your specific dog. Ask your vet about the best dog flea and tick collars that will be effective in your region and your specific dog.

Finally, if your dog already has fleas, I highly recommend you watch Samantha's video on how to remove fleas from a dog and from your home, and what works best for this.
