Bests & Worsts Reviews from Amazon

I was skeptical ordering these for my dogs because they were so cheap, I ordered 3 for 50$ on Prime and received them in two days. The first day I didn’t see much of a result and decided to wait a couple more days before sending them back. The next day I noticed the scratching had stopped, checked them over and no more fleas!! I guess it just takes a bit longer for thicker/longer haired animals. We have a German Shepard and a Shihtzu and it has been perfect for both of them! Will be purchasing again, MOST definitely.
