I am considering getting a boxer, a larger dog instead of small dog. By doing the research, I understand boxers yearn for human circle. However, I work most of the day time and wondering should I, or could I, keep him outside. I have sizeable backyard. If kept indoor all day, how do you handle his potty issue? Larger dogs have larger poops, I don't know if I can let it (smell) stand indoor all day.
