Way easier and cost effective

I have used this for years now on all of my dogs and not once have I ever found a flea, or tick. This are worth the money as well as not putting the chemicals in my dogs! Way easier by far!

After putting the collar on my girl dog, with in 12 hours she wasn’t digging her hair out. This collar is a game changer.

Satisfied Customer for Years!!! 🐾

We had used the product on our Australian Shepherd for several years. It is easy to use and doesn't require anything more than putting on the collar. We have never had fleas using this method of treatment and would recommend using it to others.
