A whole house is a big scarey place for a little guy... try limiting his area for awhile, a couple days, then opening up a little more at a time, after he seems comfortable and not so nervous. When I brought my little boys home, they were nervous, but they were limited to one floor at a time. And I had their crate out all the time so they had easy access to their comfort zone when they were scared or nervous. It didn't take long at all before they felt 'at home' in their new home. Maybe a couple days at most!
How long has it been for you? |
