My dog knows how to go outside and we also have a litter box, but sometimes she still messes up. Many people tell me don't use a litter box, but the problem is that I am gone during the day and I don't have anybody to let her out during that time. What should I do? She gets walked right before I leave and right when I come home, the time she is alone is about 9 hours. She is also crate trained. Can I keep on working with the litter box, or would she be better off just having nothing and waiting until I get home? and if the litter box is fine, how do I keep her from making accidents elsewhere?
