Bayer’s collar has a built-in ratchet system for safety purposes. Moreover, the collar has a breaking point in case our dogs’ head gets stuck somewhere.

Keep in mind that, while the collar is water-resistant, it isn’t waterproof. Soaking it in water can decrease its efficiency over time.

Moreover, the collar has an FDA certificate to prove it doesn’t contain any harmful chemical pesticides. It is also waterproof and rainproof.

One issue we had with this collar is its scent. While they say it promotes relaxation, we found it to be a bit too strong and overpowering.

Furthermore, it comes in two sizes, for bigger and smaller dogs. The collar for bigger dogs is 24 inches and the one for smaller dogs is 15 inches long.

However, keep in mind that, since it is a natural collar, the scent can be a bit overpowering. Also, since the product is made in the PRC, it is not FDA-approved.

What Are Flea Collars?

In essence, flea collars are regular collars that have flea-killing chemicals in them. They are a harmless solution to a problem that has plagued dogs for ages.

There are three main types of flea collars: repelling, treatment, and treat and repel collars.

Things to Consider

Now, let’s talk about what the most important things to consider are when looking at the best flea collars for dogs. Also, we’re going to cover which types of dogs shouldn’t wear them.

Natural vs Chemical

While chemical collars tend to be more effective, they can also have more serious side effects. On the other hand, natural flea collars are usually infused with some natural oils which means almost any dog can wear them.

Water-Resistant

We also need to think about how often our dogs get wet. Not all flea collars are waterproof, which means we would either have to take the collar off or replace it each time our dogs get wet.

Protection Period

Not all flea collars are effective for the same period of time. Some might last only a couple of months, while others can up to nine months.

Can All Dogs Wear Flea Collars?

Well, yes and no. Flea collars are safe for all breeds; however, there are four categories of dogs that shouldn’t wear flea collars.

Puppies

We wouldn’t recommend putting a flea collar on pups who are less than six weeks old. They still don’t have a fully developed immune system and their little bodies aren’t able to process the chemicals in flea collars.

Pregnant Dogs

While there haven’t been any extensive studies on the effects of flea collars on unborn puppies, most vets and animal experts advise against putting flea collars on pregnant dogs

Nursing Dogs

Again, there haven’t been any studies to show if the chemicals in the collars can influence our dogs’ milk. However, there also haven’t been studies that prove it won’t.

To be on the safe side, we recommend avoiding flea collars if your dog is nursing.

Senior Dogs

Due to different aging processes, older dogs can have a compromised immune system. Their bodies might not be able to process the chemicals the way they should, leading to some health complications.

Also, some studies show that it can deteriorate their livers or kidneys. Again, to be on the safe side, we wouldn’t recommend using flea collars on older dogs.

Bottom Line

There are so many products and gadgets nowadays that claim to be able to help our dogs with nature’s most annoying pest.

That being said, flea collars are a tried and trusted method of getting rid of these pesky insects.

As you’ve seen, our overall winner was the Seresto flea collar from Bayer. Not only does it last for eight months, but it also has a double safety system to ensure our dogs never get stuck in them.

Moreover, it is odorless and water-resistant. Also, compared to the other collars we’ve reviewed, we believe the Seresto is the most effective collar on the market right now.

Finally, we hope our list of the 10 best flea collars for dogs can help you make a more informed and educated decision the next time you go shopping for anti-flea products.
