I was just given this for both of my dogs. Since the puppy isn't old enough to take it for 2 more weeks I haven't used it. I was told that it has to be given with food or they may vomit. My pup isn't 5lbs yet though, so I will keep that in mind. He is only 3lbs I believe, so maybe I should use Frontline on him first?
I have heard raves on Comfortis though. It kills the fleas within an hour! |
