It's not a bad habit if he's waking you because he has to potty, it's good training. He doesn't want to potty in the house, but if you don't let him out he's left with no choice.
Since this is a sudden new behavior it could be a sign of a urinary track infection. In other words, he can't help it that he has to go potty. If he was mine, I'd take him to the vet and have him checked over. It can be easily cleared up with medication. |
