We have a Blue Healer pup that is great fun, but he keeps soiling my home. I have tried taking him out for walks to make sure he does his duties outside, but as soon as we came back in, he pees on the floor or on the deck. I work 1 day for only 2 hours a week and if I crate him, he poops in the crate and of course, is a real mess to clean... both dog and crate. It's really frustrating. Is there anything else I can do?
