Best Dog Flea Collar Reviews

1. Bayer Animal Health Seresto Flea and Tick Collar

This flea and tick collar is from one of the most reputable pharmaceutical giants, Bayer.

They strive to develop innovative solutions to help promote animal health, and this chemical-laden collar comes vet recommended.

Product Highlights

The Seresto collar from Bayer offers a massive eight months of continuous and highly effective flea and tick prevention.

It also protects your furry friend from sarcoptic mange and lice, so this collar really has it all; it’s no wonder vets recommend it.

With its active ingredients imidacloprid and flumethrin, this collar releases low concentrations of both over your dog’s skin and hair.

The chemicals protect your dog from many diseases that can be caused by flea and tick bites, such as Rocky Mountain spotted fever and Lymes disease.

The Bayer Animal Health Seresto Flea and Tick Collar repels and kills through contact with the insect, so they don’t have to bite your dog before they die.

Odorless and non-greasy, this collar is straightforward to put on and super low-maintenance, as there’s no need for messy monthly treatments.

It comes in two different dog sizes, over and under 18 pounds, and is also available for cats, which would work well for toy breed dogs too.

The chemicals used in this collar could prove to be toxic to some animals, so this collar should only be used if your dog suffers badly from fleas.

The Good

The Bayer Animal Health Seresto Flea and Tick Collar is highly effective at killing and repelling all manner of harmful insects, and it’s highly unlikely that you’ll need separate treatments.

The Bad

The cost of this collar and the chemicals used means that it will not appeal to everyone.

We hate that there’s a small chance that an animal could get sick from using the Bayer Seresto Collar, so remember to keep a close eye on them.

2. SOBAKEN Canes Flea and Tick Protection Collar

Our second pick for this list is a chemical-free flea and tick prevention collar from SOBAKEN that uses a new formula to offer even better protection.

Also vet recommended, this long-lasting collar is more economical than our first choice, but may need separate treatments to kill fleas and ticks as needed.

Product Highlights

This naturally repelling flea and tick collar from SOBAKEN uses a blend of spearmint, clove, and citronella oil to repel insects from your dog.

It helps protect your dog from fleas, ticks, sarcoptic mange, and lice at the same time while being completely non-toxic and hypoallergenic.

It offers long-lasting protection for up to eight months, and the new formula makes it more powerful than other natural collars.

Since the SOBAKEN Canes Flea and Tick Protection Collar has a 100% natural formula, it is safe to use on your dog starting at the age of three months.

Seldom found on flea collars, we love the fact that this collar is waterproof and will continue to be fully effective if it gets wet!

You don’t have to worry if your dog goes for an impromptu swim while out walking, and you can even bathe your dog in their collar.

This one-size-fits-all collar is suitable for small, medium, and large dogs since you just cut off any excess, leaving a little for growing room.

The company is really great since it donates $3 from every sale they make to charities involved in saving animals. 

The Good

There’s so much to love about this SOBAKEN collar since it’s natural and waterproof, and you’re saving animal lives by supporting the company!

The Bad

The all-natural ingredients won’t actually kill fleas, so it may be necessary to complement the SOBAKEN collar with another flea remedy should an infestation occur.

For instance, using a flea and tick shampoo as an extra precaution.

3. Petsmont Flea and Tick Collar

Our third choice for our list comes from Petsmont, a company offering a unique plant-based option as an alternative to synthetically made collars.

Offering a full year of protection, this is the most economical option, as well as the most eco-friendly collar on our list. 

Product Highlights

This plant-based flea and tick collar for dogs is a fantastic alternative to the majority of collars made from synthetic materials.

This all-natural collar is completely hypoallergenic, making it perfect if your dog is particularly sensitive, or if you just prefer more eco-friendly products.

Petsmont has developed an effective formula using a unique blend of peppermint, citronella, cedarwood, lemon eucalyptus, lemongrass, lavender, and geranium oil.

You get two, six-month collars in each pack offering a full year of protection for a really great price.

The Petsmont Flea and Tick Collar can be adjusted to fit any size dog from small pups to extra large hounds, and you just have to cut off any excess.

The plant-based material collar is also very soft and perfectly round to fit around your dog's neck as opposed to the oval shape of most other collars.

That makes the collar ultra-comfortable for your dog to wear, and it is effortless to fasten and remove when needed.

Petsmont also offers a 100% satisfaction guarantee with your purchase to ensure that you and your four-legged friend are happy with the collar or your money back.

The Good

We love that Petsmont developed a plant-based flea collar to offer dog owners a more environmentally-friendly option.

The value of this two-pack collar is also really great as you get a full 12 months protection for your money.

The Bad

Like most natural collars, the Petsmont Flea and Tick Collar will only repel fleas and ticks rather than kill them, so you may have to seek alternative treatments on occasion.

4. Rolf Club 3D Flea and Tick Prevention Collar

Our fourth recommendation to protect your dog from fleas is a natural collar from Rolf Club that brings new German technology to the flea collar market.

As the only natural collar we’ve come across that kills fleas as well as repels them, this list wouldn’t have been complete without it.

Product Highlights

This flea collar from Rolf Club offers six months of protection against fleas, ticks, and mosquitoes.

The new German all-natural formula is fast-acting as it kills fleas within the first 24 to 48 hours after you put the collar on your pooch.

It is also effective against flea larvae, meaning they don’t stand a chance of reinfecting your dog.

It also is flexible and comfortable for your dog to wear and is suitable for any size dog from the most petite to larger breeds.

The German technology used has been tested by veterinarians and helps to achieve great results without using any toxic ingredients.

The Rolf Club 3D Flea and Tick Prevention Collar also offers another waterproof option for you to consider, which makes it a perfect choice if your dog loves to play in the water.

The Good

We think it’s remarkable how effective the Rolf Club collar is at killing as well as repelling ticks and fleas without any toxic chemicals!

The collar also looks really comfortable to wear, and it doesn’t emit any strange smells either.

The Bad

5. Parenda Small Dog Flea and Tick Collar

The fifth and final place on our list goes to Parenda for their flea and tick treatment and prevention kits.

This is another entry for a natural collar that offers long-lasting protection for a great price and has some great new upgraded features.

Product Highlights

The Parenda collar actually comes in a pack of two, which, together, offer eight months of protection against fleas, ticks, mites, lice, and larvae.

The reason it touts itself for treatment and prevention is that the collar actually kills as well as repels ticks and fleas.

Not only that, but you also receive two tick treatment tools so that you can safely remove the tick's body from your dog.

Available in two different sizes, the tools or hooks allow for the safe removal of ticks and include instructions on how to use them.

You can treat your dog for stubborn and persistent ticks while the collar does the rest of the hard work for you.

Their patented flea repelling formula contains 100% natural ingredients, created by veterinarians and lab tested for safety.

They claim that their collars are hypoallergenic, no mess, non-greasy, odorless, safe, and effective.

The new upgraded design has added an emergency breaking point in the eco-friendly collar for your dog’s safety, and it is also water-resistant.

Thus, you can allow your dog to play in the rain or snow without worrying about reducing the effectiveness of the collar.

This fully adjustable collar is 14.96 inches long, making it perfect for smaller dogs, under 18 pounds.

Parenda also offers a 100% satisfaction guarantee so that within 45 days of purchase, you can receive a full refund if requested.

The Good

The emergency breaking point is a fantastic feature, and the free tick tools will be handy too.

We also love that the Parenda Small Dog Flea and Tick Collar is made from eco-friendly materials.

Buyers Guide

The best way to go about buying a dog flea collar is to educate yourself about what to look for when comparing different brands.

There are a considerable number of products available, so having a better understanding of how they vary will help you navigate the market.

Also, with advances in technology, new and better products are released all the time, so it’s important to do some research first.

We identified five different factors that you should consider before making your purchase and have explained why each is important.

1. Ingredients: Natural or Chemical

Choosing between a natural or chemical flea collar is perhaps the most difficult choice you’ll have to make.

Natural flea collars generally work by repelling fleas, while a chemical flea collar will kill and repel fleas.

In fact, chemical flea collars will kill absolutely everything flea-related, from eggs and larvae to fleas themselves.

If a flea attempts to jump onto your dog, a chemical flea collar will kill the flea quickly, hopefully before it even thinks about laying eggs.

They are effective but can sometimes have some not-so-nice side effects for your pet.

Natural flea collars most commonly utilize citronella oil since fleas and many other insects hate its smell.

Citronella may be mixed with a variety of other natural flea remedies, but they work by repelling rather than killing.

Natural flea collars are preferred by many people who are worried about the insecticides used in chemical flea collars.

If your dog tends to be on the sensitive side, then a natural flea collar may be more appropriate for them.

2. Water Resistance

Flea collars are seldom waterproof, but it is possible to find decent water-resistant flea collars, which should help keep the collar working effectively for longer.

While you should remove your dog’s flea collar when bathing them, a water-resistant collar will stand up to the test of time for longer.

Even if your dog isn’t the biggest fan of swimming, they can still very quickly get rained upon and splashed.

For this reason, we think it’s a good idea to choose a water-resistant flea collar, even if it does cost a little more.

3. Size and Adjustability

Another important factor is the size of the collar and matching it to the size of your dog.

Collars vary in size as much as our four-legged friends, so check that the collar you are buying can be adjusted to fit your petite pet.

If in doubt, you can buy one size bigger than you think you might need and then trim it down to size.

4. Protection Period

A lower price may originally attract you to one particular flea collar over another, but always check the protection period it offers first.

The protection period stated describes how long your dog will be protected from fleas.

If the protection period is just one month, then you’ll have to replace the flea collar in one month or less to prevent a flea invasion.

5. Effectiveness

The last factor to consider is what the flea collar is effective against.

Some collars can only kill or repel fleas, but others will also protect against ticks, lice, and other nasties.

If your dog gets ticks, then it might be worth paying extra for better protection, especially if you live in an area with Lyme disease.

Frequently Asked Questions

best dog flea collar

1. Do Flea Collars Really Work for Dogs?

Yes! Flea collars not only work but positively recommended, especially if your dog spends a lot of time outdoors.

Chemical flea collars will kill fleas that try to infect your dog, while natural collars will help repel fleas by making your dog smell very unattractive to them.

2. How Long Does It Take for a Flea Collar to Work?

As a general rule of thumb, chemical flea collars will start to work in as little as 24 hours.

Noticeable results, though, especially if your dog has a lot of fleas, may take as long as three to four weeks.

The reason it takes so long is that the collars have a slow-release design to protect your dog for longer.

Natural flea collars may take a lot longer to show results since they work to repel fleas rather than kill them.

It’s for this reason that many dog owners choose to treat their dogs first, killing the fleas and eggs, followed with a natural collar for prevention.

3. Do Flea Collars Attract Fleas?

No, flea collars either kill fleas (chemical flea collars) or repel fleas (natural flea collars).

A flea collar could be rendered ineffective if it were to get wet, but there is no way a flea collar could actually attract fleas.

4. Can You Touch a Flea Collar?

Touching a chemical flea collar is not recommended since the chemicals can rub off onto your hands, as well as in your home environment.

In fact, if your dog has a chemical flea collar, it’s recommended that you wash your hands after touching your dog.

If you have children, you must refrain from using chemical flea collars at all costs for the same reason.

Natural flea chemicals, on the other hand, are harmless, containing one or several natural ingredients such as citronella oil.

5. Can Flea Collars Give Dogs Diarrhea?

Yes, there are occasions when chemical flea collars can cause diarrhea, as well as vomiting and other nasty side-effects.

Diarrhea could occur due to an allergy to the insecticide used in the collar, or if your dog is suffering from flea collar poisoning.

Accidentally ingesting a collar containing Amitraz has been shown to be particularly dangerous for puppies and toy breeds.

There are many reasons why your dog might be suffering from diarrhea, but if you suspect that the collar caused it, then remove it immediately and visit your veterinarian.

Final Verdict

Our winner for the best dog flea collar for 2020 is the flea and tick collar from Parenda.

We absolutely love the fact that this collar uses all-natural ingredients that can kill fleas and ticks, as well as repel them.

Their patented all-natural formula is lab tested for safety and is completely hypoallergenic, so you don’t have to worry about your dog’s safety.

Another safety feature that we love is the fact that it has an emergency breaking point in case your dog gets itself into trouble.

This collar is also made from environmentally-friendly materials and is one of the cheapest options on this list, which is great news for us, pet owners.

We think you’ll end up saving money on treatments potentially needed to kill fleas in the long run.

As if that wasn’t good enough, the collar is also completely odorless and waterproof.

Team it with one of the top dog harnesses for walking, and there is no need to worry about them splashing around in puddles!

We think the Parenda Small Dog Flea and Tick Collar will make an excellent investment for you and your four-legged best friend's future.

After all, what more could you want from a dog flea collar?
