Bucky and Eevee are the same way. Some dogs will never eat well together. Eevee the little boston becomes a big monster and tries to fight bucky the Sweetheart rotti if he gets near Her food or his own food. I feed them separatly in their kennels. And have to continue this forever. They will never ever be able to eat together. Can you try to feed them separatly? It is ok to do this and good for both of them.
