It would depend on how willing the dog is to learn.

I fostered a lab x retreiver who was 1.5 and lived in a kennel. She had no idea that she wasn't supposed to pee inside. it only took me 2 weeks to get her100% house trained.

As long as you are constant, and stick to a routine, keep an eye on the dog ie make sure he/she is let out after eating, sleep etc.. just trat as if you would be house training a puppy. And remember, if he pees inside, its not his fauld its yours for not getting the timing right. Never scold a dog for peeing inside as it will make them scared, and toilet training harder.
