When I moved to a house where there had previously been dogs, and where my tenant now had 2 male dogs in her basement apartment, my male, who had been perfectly housebroken in our previous house, began marking the furniture, etc.
He would wait until I was out of the house to do it. Then, one day, I caught him in the act, and let him know in no uncertain terms that I was NOT HAPPY! (Yelled at him.)
Never Happened Again!
I know it's hard, but the key to success is vigilance. Tie his leash around your waist, or crate him when you can't keep an eye on him. You MUST LIMIT HIS FREEDOM in order to cure this! You cannot fix this if he has the freedom of the house while you are at work. Just ain't going to happen.
He also used to pee on the counter at the vet's nearly every time we were there. This stopped when I had him neutered at the age of 3.
