I ALSo use Frontline My doggie has never showed any bad reactions to Frontline.....but He is under 10lbs and his hospital has never said anything about him not being able to use it. I'm a little concerned though. I'm considering switching to Advantix..because it also repels Mosquitos..but I was always told Frontline was the best flea/tick medicine. It's kept him tick/flea free. ??? |
