We certainly have tried. He's dang smart. The majority of the tables in both the kitchen and her bedroom are low enough the he can get stuff from on top of them. I suppose we could completely remove everything from a room, but that's sort of impractical. I would go crazy moving 25 picture frames in and out of the kitchen everyday!
We do have a dog room that we occasionally let him run around in, but the door was poorly-constructed and he can push it open to get into the rest of the house. Short of buying him a house of his own, I just can't find any place to keep him.
That dog room sounds good. Can't you fix the door so he can't push it open? Does it need a new door handle? A door is easy to fix. You could put a radio in there with him to keep him company with it on a radio talk station on AM( just not Rush Limbaugh):D
Sounds like you have your mind made up to give him up.
