my husband and i live alone with our pug mix we got from craigslist last year and in the last few months he's been biting at people. he bit 2 friends as they tried to pet him from the fence and he's been biting at pretty much anyone who comes over's feet when they leave. so far altogether i'd say he's bitten and at least grazed 3 people and drawn blood on 2 others, 1 so bad she had to go see her doctor the next day. he never tries to bite me or my husband. i need some stuff i could try at home to fix it asap because my landlord heard about the really bad bite and said if it happens again he has to go.
