Aggression Towards Family Member
My Australian Shepherd is almost 6 months old and he has always been on the nippy side. He is doing better as far as that goes except for with my teenage son.
He does not bother the dog at all and is always sweet and loving to him, but the pup will growl and try to bite him when my son goes to pet him. This does not happen every time but often, which is also scary because it is unpredictable.
My trainer says this is not typical of Aussies and is concerned.
Any advice please?
