We tried a squirt bottle and it seem to help for a while anyways. Don't spray him in the face. But when you spray him say no bite at the same time you squirt him. And don't let him see the bottle. Also try bitter apple. I think if he's a pup and you try ignoring him it will just get worse. Then he will know the only way to get your attention is to bite your feet Just make sure you wear some old shoes and he will eventually grow out of it.
