Answer
You need to have your dog examined by a veterinarian as he may have a bladder infection or bladder stones. This is the very first thing one should do whenever there is a change in urination habits.

Clean that area with an enzyme cleaner to eliminate any odor there, and keep him out of that room. You might want to confine him at night.
