<human>: We recently (2 weeks ago) adopted a 1.7yr old pitbull/shepherd/shar-pei mix from a nice no-kill animal shelter that puts significant time into training their dogs. He is an incredibly smart pooch. Within two weeks we have successfully crate trained him, and command trained him. 

The issue is he still acts like a puppy by jumping on us repeatedly  (strong dog so not a small issue) and by bite-playing with our hands/feet/face when we sit on the couch/bed. 

The usual techniques of ignoring the bad behavior isn't easy when he's climbing all over us nibbling our hands and faces. Although he has shown really good command skills, he doesn't understand "off" or "No" at all and when he's that hyper he thinks anythign we do to get him off of us (no matter how calmly we do it), is us trying to play with him and he gets more hyper. 

The only thign that has worked at all is sitting up and walking away completely and staring at a wall or something. But as you can see this is pretty inconvenient when we want to watch TV and he decides its play time. 

The worst example is when we are getting ready for bed and one of us lies down before we crate him for the night, he pounces and starts biting at everything trying to play with us. EVERYTHING makes him more hyper in that situation except immediately getting up and crating him for the night. 

BTW, we go for an hour walk/jog, 1/2 hour walk, and he has a 30 min play time of fetch/tug-of-war so he is definetely getting exercise daily. 

Any help would extremely appreciated.

Can you condense the text into three sentences or less?
<bot>: Very hyper smart dog and can't calm him down. Too in-your-face with hyperness to ignore the behavior (bite/nibbling).
