Aggressive 6 week old pittbull puppy with my 3year old English Bulldog
We just got a new puppy. She play very aggressively to the pony that we have to take her away from chomping down on our 3 year old English Bulldog. He plays nice with the puppy but he's60 lbs and doesn't know his own strength. This puppy grabs on and bites his ears and neck and clamps on while making loud aggressive growling noises. I don't want a puppy who is mean and hurts my 3 year old . Suggestions??
