Hello boxer need advise? long....?

Boxers don't have long fur to keep them warm like some other dogs do. He hasn't really built up that much of a tolerance to being outside for that long, i wouldn't think. but I'm not an expert. Is it too hard to sweep and/or vacuum the hair? I have 3 dogs and 2 have long hair. I just sweep and vacuum iy up at least every other day. Maybe you could try and train him to stay off the funiture if that's an issue, rather then putting him outside?
