She says that he gets along well with other dogs, it's the cats that he's having the most trouble with. He's aggressive towards strangers but warms up after a while. He's been in obedience training for a few weeks. Making progress but still needs work. She suggests to keep him away from cats and children. Too much activity makes him nervous, growl and try to bite. He doesn't like loud noises. Other than those that...he seems to be a sweet dog.
