I used Frontline and Frontline Plus for years on three different Yorkies with no problems except that one hated the application and would run up and down the couch rubbing himself whether he had a flea when I applied it or not. I think he was just getting even with me.
I've had to switch to Advantage now because the Frontline just quit working last year. The Advantage is doing that great a job either but I don't know what else to do. |
