You need to neuter a male dog BEFORE he starts spraying. If you don't it is very hard to stop them. You can stop them. It just takes a lot of work on your part. I would kennel your dog and when you have him out of the kennel, he should be tied to you. That way, you can see him when he does bad and correct the behavior. It will take some time but that is the only way you will get him to STOP spraying in your house. In the future, you may wish to neuter your male dogs before they are sexually mature. Good luck to you.
