That is a good question, and I tried to find that out by asking what he planned to do with the dog when he got home from work. Was he willing to take him running, biking, etc., or did he just want a dog he could play ball in the yard with. The answer was the latter. I know that doesn't really answer your quesstion. But, having said that, let me ask you, what type would you recommend based on that information. I told him generally speaking I try to would stay away from any of the herding or terrier breeds.
