Okay, so I've used Frontline on Skaara (9 mo) since I got her and I really haven't had any issues with it.. We use Advantix on our doberman that seems to work well. We live in a heavily tick populated area, mostly deer ticks that we've noticed. I've been hearing a lot about the Seresto collar and my vet even mentioned it. The convenience is very appealing, but I'm not huge on her wearing an additional collar. Anyone used the Seresto collar and have any opinions? Or any recommendations on flea/tick prevention? Thanks in advance, y'all!
