Concern about my dog. Should I be worry about this.

How old is the dog? Any medical conditions?
Does the dog urinate when you leave it alone? Sneak into another room and do it? Or do it while sleeping?

He is about 3 or 4 years old he just urinated were ever the time that I had to clean it up is doing the eveing hour we are still up I stated to take the water always at night to see if that works there has not been any changes in the house. He is walk twice a day and take out to run and play when I come home from work. I am Puzzle at this and he seem find.
