maybe its got excited and didn't mean to bite, my girls dog goes when i take it out for a walk, does somersaults, jumps 4 or 5 ft in the air and barking alot, and i normally take it out b4 i go to work at 5am

maybe they can lock the dog up in a pen or somewhere else while your wife is there ??? , if your wife doesn't want to quit the job (and why should she )
