Today we made the sad decision to put down one of our dogs, the youngest one. We had been havng trouble with him being aggressive towards other animals and last night he snapped. He and another dog were barking at something outside the fence and he turned on the other dog. He grabbed her by the throat and wouldn't let go. When my husband tried to intervine he turned on him. Hubby is ok, he was wearing a thick winter jacket and heavy work gloves so he only recieved some bruises. We have no idea what kind of dog he was because he was rescued from a garbage as a young puppy. The dog he attacked was his best friend, they were inseparable, they ate together they slept together, everything.... The decision to put him down may seem like a knee jerk reaction to some, there are plenty of trainers who will work with aggressive dogs but we have small kids.... Couldn't live with myself if something happened to them.... Still, I feel like I failed this dog and it hurts a lot.
