8 Best Flea Collar for Dogs 2020

As a dog owner, we are sure you want to do right by your canine companions. That includes protecting them from parasites or other critters that might want to use your pet as a food source. You can protect them against parasites such as fleas quite simply. All you need is a flea collar!

Flea collars are a relatively budget-friendly option to keep your dog safe and healthy from fleas. Fleas can cause your dog to scratch and bite their fur repeatedly. They can also transmit other pests and parasites such as tapeworms and can even irritate skin or cause skin allergies.

A flea collar helps to protect your dog from fleas by employing a pesticide to kill or repel the pests. An added benefit comes from their little to no maintenance. Purchase one collar, and you’re set for several months!

3. Best All-Natural Flea Collar – Arava Flea & Tick Prevention Collar

Arava Flea & Tick Prevention Collar Review

If you’re worried about flea collars that use chemicals for flea and tick prevention, you’ll want to look at the Arava Flea and Tick Prevention collar. Comprised of 11 different natural ingredients, this collar uses essential oils such as peppermint, castor, citronella, and rosemary to repel pests.

How Do Flea Collars Work?

For the most part, flea collars work the same way. The collar contains the chemicals or oils needed to repel and kill fleas, ticks, mosquitos, and other pests.

Some collars utilize chemicals to offer a comprehensive solution to kill and prevent almost all kinds of pests. Other collars include solutions made with all-natural materials such as essential oils and extracts. Still, others use high-frequency waves to upset fleas and other pests.

How to Choose the Best Flea Collar for Dogs

Here are a few things to consider when finding a flea collar for your dog:

1. The treatment itself

It’s important to know what comprises the treatment for your dog. Some collars use harsh chemicals to kill or repel fleas. Others use more natural options to achieve the same effect. The first step in finding a flea collar is to determine whether you want a natural solution or a more chemical one.

How to Choose Flea Collar for Dogs

2. How your dog will react

Some dogs can get severe reactions to flea collars. The chemicals used to treat fleas can cause hives, rashes, dry skin, and other issues. If your dog has sensitive skin, consider purchasing something that is touted as hypoallergenic.

Just because a collar might use all-natural components, it may not necessarily be better for your dog’s skin. Some essential oils can also damage skin or cause allergies.

Prior to purchasing a flea collar, we recommend consulting with your vet. They’ll be able to provide some great recommendations about which flea collar you should purchase for your dog.

3. How long treatment lasts

Most flea collars work for several months. Determine how often you’d want to replace the collar and choose something that aligns. Typically, you’d probably want to purchase the one that’s effective for the longest.

As a general rule of thumb, you can find collars that will work from three to eight months.

4. The size of your dog’s neck

Not all flea collars are created equal. Some will fit just about any dog and adjust to any neck. Some, however, require that you measure your dog’s neck ahead of time so you know which size to get.

We highly recommend leaving some slack when cutting a collar for your dog. This way, your dog can grow into it as needed, especially if they’re a puppy.

5. Eradication versus prevention

Do you want to kill fleas and ticks? Or are you simply looking to prevent them? Not all flea collars will kill fleas and ticks. Some of them work to repel so pests don’t cling to your dog in the first place.

Determine what you’re looking to accomplish, and then you can go from there!

Flea Collar for Dogs FAQs

Flea Collar for Dogs

1. How much should I spend on a flea collar?

You can look to spend anywhere from $7 all the way to $50+ for a flea collar. It depends on the brand, if it’s all-natural or made with chemicals, who the manufacturer is, and what specifically the flea collar prevents or kills.

For the most part, flea collars aren’t all that expensive. You can find something effective to fit almost any budget.

2. How long do flea collars last?

Flea collars usually last for a span of months. Some will last for three months while some might work for up to a year.

Consider the time of year when you purchase your collar. That way, you can hopefully avoid needing to purchase another one.

3. Which is better: chemical flea collars or all-natural flea collars?

It really comes down to personal preference. Some chemical collars do a much better job of eradicating fleas, ticks, and other pets. Conversely, these often cause serious reactions to some dogs or even allergies. These don’t happen as much with all-natural collars.

All-natural flea collars use essential oils and other natural substances to repel fleas and ticks. They very rarely kill them. So these are perfect if you’re just looking to repel. Consider a chemical collar if you need to kill them.

Also, natural collars are probably more likely to give up a strong scene versus others.


In this article, we touched on some of the basics of flea collars. Flea collars are a great way to keep your dogs happy and healthy against fleas, ticks, and mosquitos. Although designs, treatments, and sizes vary, by far and large flea collars effectively protect dogs.

We hope you found this article informative! We are sure you’ll be able to find the perfect collar for your canine companion!
