I was just wondering why you have to put the flea products on between dogs shoulder blades. I just tried to put Sammy's on him and he does everything but stand on his head. It is very frustrating because this stuff is so expensive and I don't want to waste it. When I need him to sit up he lays on his back like he knows what is coming. It would be perfect if I could put it on his chest. Does anyone know why you have to put it between their shoulder blades? Thanks!
