Introducing A New Dog
I have 3 dogs, an Aussie (neutered male) a Mini Aussie (spayed female) and a border Collie/Aussie (spayed female). I recently rescued a 6 month old Aussie (neutered male). The male is not accepting the puppy. He bullies him even going as far as attacking him. Any suggestions or should I find a new home for the puppy?
