Why is it that when we go to the vet, he can hold her down and pry open her mouth and its no problem, she just sits there and takes it, but then when I try to do it she goes NUTS She squirms all around, and her head. . . it's everywhere, its like she's trying to fight for her life. I just don't understand what he's doing differently. Maybe she hates me because of all the recent vet vistis. I don't know. I am discouraged.
