I was thinking about getting a doggy door on the back door so that he could just go in and out as he pleased. Is this a good idea? Does anyone have experience with this? I want something nice enough that it won't let out the hot/cool air and run up my bills.
Also I don't want him to try to dig out so any ideas there? Would it be cruel to put barb wire along the bottom so that he doesn't even try it?
