With a new puppy due soon we decided we needed a better outdoor area than we currently have for Jack. So we fenced in a cement area that is surrounded by shrubs. Here is the problem. Jack will go out there and do his #2 duty just fine but refuses to do his #1 duty. Is it too much to ask of a male dog to do his #1 duty on cement? He does lift his leg so we thought the bushes would work but so far no success. When I know he has gotta go, I can only keep him on the cement for so long because I know his little bladder is ready burst. Although we live in the city, our yard is heavily wooded and we have fear of wildlife predators. Fencing in the yard is not an option. Any suggestions?
