Many years ago, my most cooperative dog cried out in pain when the vet was trying to draw blood. I tried to calm her and he threw me out of the examining room. I heard her cry out again as he completed the process, and tears are streaming down my face. I could barely drive home, I was so upset. Needless to say we never darkened the door of that veterinary clinic again. When I left that exam room, I should have taken her with me, I was just too stunned to think straight.
