My wife and I came home to find that our German Shepherd had killed our terrier mix. The terrier mix had epilepsy, and the Shepherd had gotten aggressive towards him two times in the past 3 years only when he was having a seizure. In the past seizures, she seemed like she either was trying to hold him down by the throat. She was never aggressive towards him, our other dog, or my wife or I. She would play tug of war and let me take things out of her mouth without growling or showing any signs of aggression. Our concern is that we have a chihuahua who is sickly with diabetes, and we just don’t trust her around our other dog. Should I just have her euthanized, try to bring her to a rescue facility, or try to rehome her in an only dog home. She is a sweet loving dog, but if I bring her to the pound; I’m sure they are going to destroy her.
