You NEED some family member, maybe yourslef, to spend some time training your dog. Pay attention to when he pees inside. To Where. To what circumstances. A basic obedience class will do wonders for your dog, and for his relationship with all of you.

If "no one has time" then why have a dog at all?

How long have you had him? Has he been to the vet to make sure it's not a medical problem?
