Only been a few days but I can tell it’s powerful. My husky hangs outside in the middle of florida theirs all sorts of everything here. Other non prescription medicines were too weak for my big dog. He’s 75 pounds and within 1 hour of applying it along his back, the fleas started reacting. The first day he was scratching quite a bit but now it seems he has relief.

This product works great on my dog when others I tried didn’t.
