Flea Collar for Dogs: Protecting Your Canine Friends

Flea and tick season comes and goes every year and protecting our beloved pets from these troublesome little bugs is important. Not only are you protecting your pet but also the rest of your family.

Fleas and ticks can cause an array of health issues on your dog, so it's important to know if and when your dog is sick so you can start a proper treatment plan for your pet.

Before going to the store and purchasing just any flea collar for your pet, it's important to understand how they work, what alternatives you can choose from, and what dangers might be posed to you, your pet, or your family when using a flea and tick collar for dogs or cats. 

How Do Flea Collars Work?

The way that a flea or tick collar for dogs works is one of two ways. One way that flea collars work is by emitting a gas that is toxic to fleas and ticks, preventing them from biting and infecting your animal.

The other type of flea collar is one that releases a chemical that is absorbed into the subcutaneous fat layer (uppermost layer) of your dog or cat's skin.

With these kinds of collar ticks and fleas are killed off after biting into your pet and ingesting these poisonous chemicals 

The first kind of collar that emits a toxic gas is only effective when the fleas and ticks are within close proximity of the collar, Whereas the collars that let the chemical seep into the pet's fatty layer are safer and proven to be more effective. The chemicals, which are tested and safe for your pet, move about on their skin, covering more ground for flea and tick protection. 

When Should I Use a Flea Collar on my Pet?

Flea and tick collars like the Seresto flea and tick collars for dogs and our Natural Flea & Tick Collar are effective for keeping your pets safe. They are beneficial when your dog or cat is spending more time outdoors in an environment where fleas and ticks are most prominent.

Flea collars are also most effective when used in conjunction with other preventative products and proper pet hygiene

What Alternatives are Available Instead of Using a Collar?

Spot treatments are an alternative or even an additional treatment in some cases for flea and tick control for your cats and dogs. These spot treatments are a small amount of special ointment that's applied to the back of your pet’s neck.

Typically, this form of treatment will protect your pet for a few months and can be a safe alternative for households with multiple pets or with young children. This kind of alternative is good for the treatment of a pet that is already infested with fleas and will typically eliminate all fleas within 24 hours’ time. 

What Dangers are Posed with Using a Flea Collar?

The chemical that works against fleas is directly on the collar and therefore will rub off on anything that it comes in contact with. This includes your hands as well as small children who are playing with the pet that happen to grab the collar.

It’s important to wash your hands after touching your pet's flea collar. Just as importantly, to teach your kids the importance of not touching the collar and to wash their hands immediately if they come in contact with the collar. 

What Else Should I Know About Flea Collars?

A few other important facts to know about flea collars and their use include knowing when to change the collar and how the collar should be worn by your animal. All of this information that is specific to the collar that you buy for your pet should be on the packaging that the collar came with. Changing the collar during the time frames indicated by the manufacturer will help to ensure constant protection against fleas and ticks.

As far as how your pet should wear the collar is another recommendation made by the manufacturer that should be followed. Just like with any other collar, you should be able to fit two fingers between the collar and your pet's neck to ensure that it is not too tight for them. 


Flea collars are a great way for you to protect your pet and your family from flea infestations as well as any issues that could arise from having ticks. There are two kinds of flea collars and it’s important to understand the difference between them before putting one on your pet.

Do keep in mind that there are alternative treatments other than using a flea collar. For one, you can use coconut oil for dogs to repel fleas and ticks. Be sure to talk to your dog or cats’ vet and see what course of treatment they recommend. 

Do flea collars work?

Flea collars do and don’t work, depending on the flea situation that your dog is facing. Also, if the fleas move away from the collar on your dog or cat's coat you may still find them roaming around on your pet. Some fleas have built up a tolerance or immunity towards the chemicals in the collar.

How do flea collars work?

Flea collars use chemicals to both repel and treat flea problems. Usually, collars will do one or the other action. The ones that repel work by emitting a gas that keeps fleas away. While the ones that treat a flea problem work by providing a chemical that seeps into the subcutaneous layer of fat of your pet that kills off the fleas.

Are flea collars safe?

The chemicals in flea collars are potent but are becoming safer and safer as new products are being made and improved. Vets recommend certain flea collars for pets who are facing a flea problem, such as the Seresto flea collar.
