5 Best Flea Collars for Dogs in 2021 (Rated & Reviewed)

We all know very well how ticks and fleas can cause difficulties when found on the skin of our four-legged friends.

Then comes the long and difficult process of dealing with the removal of these pesky parasites. In no way is this pleasant for both your dog and you as a responsible dog parent.

To avoid getting into such a situation in the first place, we have prepared the ultimate list of the best flea collars for dogs. However, since no flea collar is perfect, we will cover things we like and don’t like about each of them so that you can make an informed decision.

Also, we will first show you which characteristics of collars to pay attention to when making a purchase. This brief guide will help you in selecting your personal favorites.

Let’s get into it right away!

How to Choose the Best Flea Collar for Dogs

Before we start analyzing our favorites, it is important to pay attention to a few characteristics.

These tips will surely save you time when choosing the best flea collar for your dog. The features we singled out are:

Factor #1 – Sizing

Before any purchase, it is essential to take note of the size of your dog.

Whether your dog belongs to a small or extremely large breed, we recommend that you measure the neck circumference. You can take a tailor’s meter and determine the length.

Feel free to add an inch or two to the number to make the flea collar fit more loosely and avoid it being too tight.

Factor #2 – Ingredients

You should pay attention to the potentially toxic chemicals that you can find in some flea collars for dogs.

How do we avoid worrying about this entirely?

We focus on flea collars that use only natural ingredients.

The use of essential oils makes a positive contribution. They can prevent the appearance and spread of parasites on the skin of your dog without any harm.

However, not all chemical ingredients are bad either! There will be a few collars on our list which don’t use 100% natural ingredients. Still, dog parents around the world have bought them for their pooches and have faced no issues.

Factor #3 – Effectiveness

The effectiveness and long-lasting results are the second most crucial thing after safety.

The collar must offer almost instant results so that your dog is safe from the get-go. Many flea collars show their effect within 24 hours, and we like seeing efficiency and fast results!

On the other hand, your flea collar of choice should also offer longer protection (of about 6 to 8 months at least).

Factor #4 – Your Dog’s Age

The dog’s age is a factor that many dog parents ignore.

The effect of a flea collar on a dog younger than seven weeks (and even up to three months) is minor. A flea collar on the puppy’s neck will extract its natural oils and will not kill parasites.

It is best to consult a vet if you are considering buying a collar for your puppy.
