Rewarding good behavior, ignoring bad behavior.
At a few months short if being 2 years old Toby is really coming along.
Rewarding good behavior and ignoring bad behavior really works. Hopefully this experience can helps others. It wasn't easy and took 1 1/2 years.
He use to try to initiate play by jumping up and biting my butt or legs - hard.. When he would do that I would simply walk away. Gradually he started to just jump up and bat at me. I made a conscious effort to ALWAYS chase him (which is what he wanted) or otherwise engage in play EVERY time he just jumped up genlty, and ignore him if he bit. He now barely ever bites at me, but I still always return play to reinforce his 'good' behavior.
My feet on a ottoman had the same issue where he liked biting them. I used the same technique of ignoring biting, but if he only grabs gently at them I make sure I always get up and chase or play to reinforce this also.
