6 Best Flea Collars for Dogs – Keep Your Dog Protected

seresto dog collars

When my Cockapoo named Mozzie (pronounced like Ozzy with an M in front) was about a year old, I took him to the vet for a checkup. I was shocked when they found that he had fleas.

I had been faithful in putting topical treatments on him every month as recommended. But apparently, the topical treatment I was using was not water-resistant and washed off when I gave him a bath.

Ever since then, I’ve been a bit paranoid about fleas.

I check his fur regularly to make sure that he hasn’t attracted fleas, which could make him uncomfortable or damage his health. He’s my baby, and I do everything I can to protect him!

While topical and oral flea treatments are most recommended by vets, a flea collar can offer your dog an extra line of protection if they spend most of their time outside or if they’ll be out in areas where they’re likely to come in contact with fleas and ticks.

Some flea collars offer protection from mosquitoes, lice, or other pests as well.

This flea collar has no odor and doesn’t have a greasy feel to it at all. It also keeps working even if your dog gets a bath or goes swimming.

Buyer’s Guide: What to Look Before Purchasing a Flea Collar For Dogs

Here is a list of factors worth considering before choosing a flea and tick-repellent collar for your canine companion.

Ingredients

Flea collars use different combinations of either chemicals or natural oils.

Some common chemical ingredients that are generally considered safe include:

  • Deltamethrin
  • Amitraz
  • Pyriproxifen
  • Propoxur

Tetrachlorvinphos (TCVP) is also relatively common in flea collars, though it is a more controversial ingredient. Some scientists believe that it is a human carcinogen and possibly a neurotoxin for people and pets.

Occasionally, dogs have skin reactions due to the chemicals in flea collars. If that happens, you can learn how to treat a chemical burn from a flea collar and treat it at home.

Natural ways to kill fleas and ticks include using essential oils. Skin irritation is much less likely with a natural collar, though not impossible.

Duration

Flea collars each last a different amount of time, ranging from 4 months up to a whole year.

Keep in mind that if your dog likes to go swimming or if you keep the flea collar on your dog during bath time, this can reduce the amount of time that the collar can repel fleas.

While it’s super nice not to have to worry about giving your dog monthly flea and tick prevention, you also could forget to change their flea and tick collar at the right time.

One way to remember when it’s time to change their collar is to set up a recurring delivery with Amazon.

Odor Vs Odorless

Most flea collars that use chemical ingredients are odorless, though it’s always best to check the product description to be sure.

With a natural flea and tick collar, it works with essential oils which are scented. Depending on the combination of oils used, so might either love or hate the scent.

If you are shopping for a natural flea collar, be sure to read through the ingredients list to see if you like the smell of the oils used. Some common scents are:

  • Citronella
  • Clove
  • Spearmint
  • Peppermint
  • Cedarwood

FAQs

How Do Flea Collars Work?

When you get a new flea collar, you will stretch it out to activate it. Then you will place secure it around your dog’s neck and adjust it. Make sure that it is not too tight or too loose.

Then trim off any excess material. If you have a puppy, don’t trim off too much of the excess. You will likely need to adjust the puppy collar over time as your dog grows.

Once the collar is on your dog, the ingredients will start to evenly distribute throughout their skin and fur.

Depending on the ingredients, the flea and tick collar will either repel, treat, or both.

A repellent collar emits gas to keep pests away from your pup.

Flea treatment collars work by killing pests either when they bite your dog or on contact before they can bite.

Are Flea Collars Safe?

Dog Flea collars are a somewhat controversial topic. While they are known for being quite effective, there are some downsides.

The chemicals used in a flea collar work by direct contact. This means that anytime your dog rubs up against you or your furniture, some of those chemicals could transfer.

It is recommended that you wash your hands after touching your dog if they are wearing a flea collar. It is also not recommended that you sleep in the same bed as your dog if they wear flea collars.

Skin irritation can occur from the chemicals used. If your dog is going to have an adverse reaction to wearing a flea and tick collar, it will likely happen within the first few days of you putting it on them.

All that said, flea collars have been used by pet parents for decades to repel fleas and ticks. Talk to your vet if you are concerned about if a flea and tick-repellent collar is the right choice for your pup.

Do Flea Collars Kill Fleas Instantly?

Flea collars do not kill fleas instantly.

It can take up to a few days before it kills fleas everywhere on your dog’s body because you have to wait for the active ingredients to distribute from the collar down through the tail.

Depending on the collar, it may only kill adult fleas and ticks, or it may kill flea eggs and larvae as well.

Conclusion

Fleas and ticks can cause more than just itching and irritation for your pup. Bites can lead to anemia, Lyme disease, and other health concerns.

Pet owners should try to always keep their dogs protected from these dangers. Luckily, solutions are quite affordable and you don’t even need a prescription from your vet.

I hope this article has helped you understand the ins and outs of shopping for a flea and tick collar for your dog.
