HOLY (INSERT BAD DESCRIPTIVE WORD HERE!)
OMG I DO think you need to document and report EVERYTHING - take pictures of his welts before they go away -

poor baby.....and anything else you can think of - see if you can get someone
who was there to comment and document this whole ordeal - that's Awful !
that made me truly drop my jaw reading that....I know we tend to be overprotective but a vet should never handle a fearful dog like that and she sounds like an coldhearted woman that treat a dog that bad....why is she even a vet if she acts like that around a poor scared animal ????
poor baby - I feel so bad for him - and you too - but man - I would be insane with anger - no one would ever be allowed to touch my girls like that. Can I do anything to help you ?????
