How Do flea collars work?

The basics of how a flea collar works are by either repelling or treating. to better explain this, it means that when collars are treating, they release some type of medication that will treat your dog’s skin through entering the fat layers in their skin.

But a flea would have to bite to be killed in this situation. On the flip side, this same type of collar can also emit an active ingredient that will kill fleas and ticks before they even bite.

The other type of flea collar is repelling, and this is simply a collar that emits gas to repel ticks and fleas away from your dog. Read more about how flea collars work here.

How long do flea collars last?

You can expect a flea collar to last from anywhere between a few months up till 8 months. They usually don’t kick in until 24hours after putting it onto your dog, so don’t expect an immediate difference when you use it for the first time.

Ok! Now its time to learn how to choose a good product. because there will be few things to consider first before heading out and making a purchase.

Things to consider when buying a flea collar

There’s gonna be a bunch of different options and features that you’ll find in just about every flea collar. And to make things worse, their features and benefits are almost exactly the same on each. So to make things a little easier I’ve listed out a few things that you might need to consider first before buying.


You’ll want to be sure that the materials and protection used in the collar will be ok on your dog’s skin. Natural ingredients and oiks are your best bet, but if your dog has a specific skin condition, then just be sure to choose a collar that won’t further affect it.


If your dog is anything like mine, then she/he will want to take a dip every so often. There’s nothing worse than your dog jumping in only to find that the collar doesn’t work anymore. In most cases, this should be fine, but just be sure to check out the details first.

Length of protection

As I mentioned earlier, some collars will only work for a few months before they become ineffective. so if you’re not prepared to replace the collar every few months, then make sure to check how long it’s expected to last first.


This goes without saying for any collar that you purchase. Always make sure that it’s a suitable size for your breed, and will not cause any chocking or break due to your dog being too strong for it. Check out the breeds that are listed for the collar on the company sales page.
