I currently have my dogs in a kennel on a concrete floor until a large fence can be built in our yard for them (just moved to this house). We have dog houses for them that they can sleep in but of course, their waste ends up on the concrete floor inside the kennel. Are there any tips anyone can give me that will help me with cleaning the floors? We have a scooper to pick up the solid stuff but there is a real bad urine smell and we can't seem to get rid of it. I would use a power washer or a hose, but it's winter and the hoses are frozen. Any help anyone could provide would be awesome!
