Eight Year Old Dog Still Uses House-breaking Pads?

I have lived with my boyfriend in his condo for about a year now. He's had his dog since puppy-hood. He got the dog to use puppy pads, but stopped there. I think he felt guilty because he works long hours, I don't know. But now I'm there and walk him frequently. No change. He'll pee on it 10 minutes after we're back inside or right in front of you, no problem. We have no yard so I can't move the pad outside. I'm clueless about where to start and tired of looking at dog pee.
