For many dogs and owners, spending time outdoors is a favorite pastime. From daily walks and hikes to long camping trips and adventures, our canine friends accompany us to many exciting places. Just as we take precautions for our safety, we also do so for our pets. This includes using flea collars to help protect pets from these parasites. Finding the best flea collar for dogs, especially those that spend a lot of time outside, is a big part of keeping them safe and healthy. The best flea collar for dogs is the Hartz Ultra Guard Pro, but we’ve got some other picks for dog sizes (and an eco option too).

Why Do Dogs Need Flea & Tick Protection?

Flea and tick collars work to prevent infestation by these harmful pests. A flea infestation is no joke. Fleas lay a lot of eggs, about 40 to 50 a day, which can quickly become a painful problem. Fleas carry diseases that are spread after they bite infected animals. These diseases include tapeworms, bubonic plague, Bartonellosis, Tungiasis, and Murine typhus. Ticks bite and attach to the skin and then feed on the blood. Ticks are quite harmful as they stay on your dog and feed for a few days. They carry a bacterial infection called Lyme disease. Lyme disease can affect humans and even cats. There are various kinds of ticks, and all are dangerous.

Parasite prevention methods can help to protect these disease-carrying pests from hurting your dog. They contain ingredients that repel, paralyze, and sometimes kill ticks and fleas.

Many of these collars contain repellents. Others use insecticides and work by dispensing pest-control chemicals on the skin and fur. What will be most effective for your dog depends on your pet’s size and specific circumstances. If you suspect your dog already has an infestation, it is best to contact your veterinarian for the next steps, as many over-the-counter will not be enough to treat the problem. Your pup may need oral or topical medication to clear out an infestation fully.

Pest prevention collars generally use chemicals or natural oils to repel pests. Some will use more chemicals than others, as some products repel, and others kill pests. Sometimes pets can have a skin reaction to ingredients in a product, so always observe your pet after using any new product on them. If you have a pet with sensitive skin or allergies or are an owner with these sensitivities, look for products that use natural ingredients rather than chemicals.

5 Chemicals Commonly Found In Pest Control Collars

  1. Amitraz
  2. Deltamethrin
  3. Methoprene
  4. Propoxur
  5. Pyriproxyfen

Tetrachlorvinphos (TCVP) is another chemical found in many collars, which the EPA has classified as a possible human carcinogen. While the chemical is incredibly effective at killing fleas, lice, eggs, and larvae, it can be harmful to humans and pets if not used according to product specifications. Owners who are pregnant or have small children may want to pick a product that does not contain the chemical.

Essential oils like citronella, clove, peppermint, cinnamon, lemongrass, basil, sandalwood, and tea tree oil are all examples that can be found in some pest control products.

Dog Gone Smart Unbugz-It Bug Repellant Bandanna Review

Dog Gone Smart Unbugz It Bug Repellant Bandanna

View on Amazon | View on Chewy

A bandanna is not a traditional pest control collar, but the one from Dog Gone is worth mentioning. Many of us have pets that do not like collars and protest wearing pest-repellant collars. The bandana has bug-repellent protection bound into the fabric fibers. It is odorless and lasts through 25 washes. Machine washable, but do not machine dry.

It has an adjustable clasp and is far more comfortable than a collar for some dogs. It works to repel fleas, ticks, mosquitoes, and other bugs that might try to bite your pets. An excellent option for long outings, camping trips, and other events when your pup needs protection and may protest a traditional pest prevention collar. The product also has less rubbing around the neck for dogs with sensitivity in that area.

Pros Cons
Easy-adjust clips May not be as effective as some pest control collars
Lasts up to 25 washes
Natural cotton fabric
Easy adjust clips


Products To Avoid

Not every product is safe, despite what it says on the packaging. There are a few to watch out for. Never use products that are not specifically made for dogs to use.


We do not recommend any Seresto flea and tick collars. According to USA Today, these products have been linked to deaths, hair loss, rashes, and neurological side effects over the years, though the EPA has not issued a warning. However, several pet deaths and human injuries have been connected to these collars.

Additional Flea & Tick Prevention Methods

Preventing parasites and dealing with infestation and bites is a challenging yet unavoidable part of dog ownership. If your pet spends any time outside, you must consider how to handle pests. Pest prevention collars can be effective and are very convenient for owners. However, in many cases, these alone are not enough. Plenty of other flea control choices include topical, chewable, or sprays for your home and yard, shampoo, repellents, and additional options, including subscriptions. Some owners may even use a homemade flea and tick prevention method.

If you are concerned that your pup has an active pest infestation, it is best to seek out the advice of your veterinarian before trying any of these do-it-at-home options. This is especially true if your dog has other health concerns like flea allergies or respiratory issues. Learn more about allergy symptoms to make sure you can identify if your pup is having a bad reaction. With proper prevention and treatment, your dog can live and enjoy the outdoors pest free.
