I'm SOO glad this is posted because I'm having the exact same problem with my Oliver. He's a little over 10 weeks old (we got him at 9 weeks) and he bites constantly! I know he's only playing and its because he's hyper but his biting (especially the feet and fingers) is getting harder. I just don't want him to become a biter when he's around other people. I've tried to say "no bite!" and give him a chew toy, I've tried giving him a teething bone and I've put him back in his cage for time-outs....those don't seem to be so helpful but what I DID find helpful was when he bites and I jerk away and say "ouch!" he steps back and looks at me and then licks me. I'd like to think he knows he hurt me and doesn't want to do it again but maybe I just scared him haha but either way it seems to help when you say "Ow"

I'm reeeeeally hoping he grows out of it!!
