I have already started entering her into rescue groups, because there is no way I can keep her. There are still other dogs in the house and I can't let this happen again. I should have knew. She bit another dog of theirs over food but not bad at all and I should have knew from then that it was a matter of time before she did something like this. Im just so disappointed in her. She came so far with training and being good but food and other dogs was always her problem. Some of my co-workers who have known her longer then I (i work at a doggy daycare) suggested I put her down, but I just can't even bare the thought. I'm terribley sad that I'm losing one of my bestfriends, hiking buddies, and partner.
