My vet told me that dogs have more reactions to frontline than to advantage. So I use the advantage with no problems. But maybe she just feels it and decides she doesn't want it there anymore! lol Is the skin irritated after it's applied? Red or scaley? I was also told that the formulas for flea AND tick for both frontline and advantage cause much much more reactions than the simple flea preventative.. ??
