Hi my 9 week old Staffy puppy is having what I can only describe as turning herself inside-out tantrums, growling and biting at my hands. She seems to mean business and I'm not convinced it's normal puppy behaviour. It occurs when she is restrained for any reason ( for example at puppy class I was asked to heal her on lead and she flipped out) . Or if I keep her away from a situation/ our older dog or if I am carrying her and she wants to get down. Today at the vets she through a paddy and bit the vet, the vet physically pinned her down and said we Are heading for a big problem ! It was all extremely stressful and I'd like to know how normal this is ? It is certainly not playing or mouthing. She seems very angry ? I'm increasingly worried about her growing into an aggressive dog...
