I have a 1 year old rescued Treeing Walker Coonhound who is beautifully mannered on walks and with other people. But lately, when we play, he has taken to jumping and grabbing.

He was found by the APL as an 8 week old pup on a road side, and had already gone through 4 homes when I got him as a 7 month old. Very sweet tempered and responsive.

And I know that as a high energy dog that being kenneled while I am at work is hard, but he is still chewing and there is no one else at home to work with him.

I have been looking at the recommendations on the site and have been trying to use the "Ouch"/timeout with him since I read about it last Friday, but when that's coupled with jumping its not easy. And since it isn't happening with other people I wasn't sure how to apply the recommendations regarding jumping.

Any recommendations are appreciated.
