We've one back to it from Multi as we went back to a dedicated hearteworm med. The only thing I see and am testing, is that I think it irritates their skin or dries it out making it itchy. After a few days, they seem to try to scratch as close to the application area quite a bit. Next application I may try a bath a day or 2 after, just to get it out of the hair. Of course, with a shampoo that won't wash away the medication.
As far as working, we've never had a flea, tick or anything, but they're either in the house or back yard only, most of the time. And they have free access to the back yard. |
