Ohhhhhhh,
My dog Rocky started to do this almost immediately after being neutered!!!!!!!
He can pick out the submissive dogs, or the ones that are smaller than him, that he knows he can 'have' and pins them down, growling and snarling!!!!! He has never ever hurt one, but its still no good saying that he is not vicious when he is scaring the bejeezuz out of some poor dog!
When it comes to dogs that either can kick his ass adn will, or are too big for him to roll over, he either ignores those taht would have him, ie pretends they dont exist (he doesnt even prick his ears, or make his tail go 'poink!), just looks past them, or with the big confident ones, he dances round them barking and snarling but never ever makes contact!
Basically, he is not confident any more, so he likes to bully other dogs, it makes him feel good i think!!!!! (makes me feel crap, specially when owners of softy dogs run away when they see us coming!)
Id love to see a behaviourist, one with a stooge dog, the kind that come across all soft adn docile, and would then kick his little terrorist ass for him!!!!!!
