13 Best Flea Collars for Dogs in 2023

A dog flea collar is a plastic band that pups wear around their necks to kill fleas. It releases pesticides slowly that spread over the skin to repel and kill fleas, as well as destroy their eggs.

This keeps your dog healthier by reducing the infections and hair loss caused by these pests. It also minimizes scratching, which is very uncomfortable.

There is a wide variety of these bands in the market, each with different features. In this article, we look at all these so that you can have an easier time picking the best flea collar for dogs.

5 Best Flea Collars for Dogs: Review

1. Best Overall: Sobaken Flea and Tick Collar

• Target Group: All Dog Sizes
• Protection Period: 8 Months
• Weight: 0.9 oz.

Sobaken's flea and tick collar is our best product because it provides long-term reliable protection. It is one of the best natural flea collars for dogs due to its 100% natural formula, which is non-toxic and hypoallergenic. This formulation is vet-recommended because it is pet-friendly and highly effective at repelling ticks & fleas.

That said, the product offers 8 months of protection, in which it continuously releases a low concentration of the formula. This spreads over your pet's skin and coat for even coverage.

The collar is waterproof, and therefore, it remains effective even after your dog takes a path or plays in the rain.

Another benefit you get is compatibility with all dog sizes, provided they are more than three months old. For every collar sold, $3 is donated to charity organizations for saving animals. As such, you protect your pet while saving an animal somewhere in the world.

The only problem is that the collar is not reflective to improve nighttime visibility for safety purposes.

How to Buy the Best Flea Collars for Dogs

1. Natural or Chemical

Most chemical dog flea collars are fast-acting because the ingredients are specifically formulated to spread and kill quickly. Typically, this takes anywhere from 12 - 24 hours.

However, they may cause allergic reactions to you or your dog. Make sure you handle them with care and if you spot any reaction on your dog, remove the collar immediately.

On the other hand, all-natural dog-collar formulas contain essential oils that are safe for you, your dog, and the environment. They may have a slower action, but we highly recommend them. The ideal one to consider is Sobaken's flea and tick collar.

2. Size and Adjustability

For the collar to work, it must fit. Size is usually given as the maximum neck circumference that the collar can fit. In some cases, the maximum or minimum compatible dog weight or age is given in pounds and weeks, respectively.

3. Protection Period

Given in months, this is a measure of how long the collar's active ingredients will be effective. The longer it is, the better, which is why the 8-month Sobaken's piece stands out.

4. Effectiveness

Some collars kill adult fleas, but cannot destroy eggs, larvae, or fleas in other stages of the growth cycle. These are less effective because they cannot handle an infestation.

For maximum effectiveness, we recommend getting a collar that can break the life cycle of these pests, and the perfect example is Primova's flea collar.

5. Water Resistance

Dog's like to play around with water, either by swimming or being rained on. On top of this, it is important to bathe your pooch every once in a while. For these reasons, you should get a water-resistant flea collar, which remains effective after being exposed to moisture.

6. Tick Protection

Apart from flea protection, you should consider getting a collar that kills other pests like ticks, mosquitoes, and the like. Using Primova's flea and tick collar as an example, it kills over 500 other insects, and we highly recommend it.

Q&A

1. Are Flea Collars Safe for Dogs?

Yes, they are. However, the collars are only safe if their target group matches your dog's description, and do not cause allergic reactions. Allergies are common when using the chemical collar type.

2. Can Flea Collars Be Worn by All Dogs?

No. Most flea and tick collars are not safe to use on young puppies, senior dogs, or pregnant/nursing bitches. Make sure you read the product's target group before buying and consult your vet if you are not sure.

3. How Long Does It Take for A Flea Collar to Work?

This depends on how fast its formula works. Some take as little as 12 hours, while others take up to 48 hours. The faster, the better.

It is worth mentioning that the oils and chemicals might take more time to spread across the whole body, up to the tail. Just give the collar some time to see the results.

4. Is It Okay to Get A Dog Flea Collar Wet?

Even though most flea collars are water-resistant, their effectiveness might reduce slightly when exposed to moisture. As such, if you can, remove the collar before swimming or bathing your pooch.

Also, some pesticides in the collar might be harmful to water animals. Therefore, when swimming in the river, lake, or any other water body, remove the collar.

5. When Should I Change the Collar for My Dog?

Follow the manufacturer's guidelines strictly to ensure maximum protection. This should be after 6 - 12 months.
