OMG was what I thought when I read the subject title.
Scuse my ignorance but I assumed that any issues a dog has is usually down to how it's been raised/treated - 'it's not the breed, it's the owner'. Like others have said, surely this is a case of a pup pushing the boundaries and being allowed to get away with it thereby reinforcing the bad behaviour?
Poor little mite, fingers crossed someone with doggie sense snaps him up and turns him into a happy chappie.
