All good replies so far! I have tried the loud NO! and the laying on their back trick and have had success using those. I also do this silly thing sometimes when Howie starts to chew my fingers where in a loud high pitched tone I say "BUP!" I have no idea why, but it works. And I keep repeating it. And after doing it a few times he starts going in to bite and then not following through and he gets frustrated and relents. It's pretty funny.
Also, age helped. The older he gets, the better he's behaved! Hang in there!
