Hi and welcome to YT
!! SO glad you have Boogi, rather than his former owners...my gosh, how could they do that to him? He deserves better than that, and it sounds like he is now getting just that. As long as your basement is comfy and not too cold for him (yorkies can get quite cold due their thinner hair), it's probably a nice place for him to be when you're gone. Do you think it will be too cold in the winter though?
