You are in a tough situation. I feel like @LifeofRubie and would probably want to do the same. But having grandchildren myself I understand your dilemma. But this kind of neglect drive me insane and I would so want to take that dog from her! I would never be able to control myself. I'm surprised the vet didn't say something. For this to happen and her to just leave the dog for days on end just blows my mind. Literally just blows my mind. Animal abuse. That's what it is.
