Oh, that's soooooo sad!!! I'm so sorry! Our great pyrranese is really mean to other dogs and people so we have to put a muzzle on her. Again, I'm so sorry. That must be really hard for you and your family! Tears!!! We had to put our dog Maverick down because he had cancer and was old. Sad.
Sorry, that must suck for you. Losing a dog is the worst.
Thats so sad!! I’m so sorry! I heard about this once where my cousins dog bit their other dog, but it was because the little dog who got bit accidentally put her claws in one of the bigger dogs wounds. The bigger dog was just threatened. Maybe thats what happened to your dog? I am so, so sorry!!
