If your dog is peeing inside the house, let's first look at some of the possible reasons. This may help to determine the best course of action. If he is already house trained, it could be either an accident or territory marking. See Dog territory marking – How to Stop it.

It may be an accident if your dog was left too long without an opportunity to go outside, or he may have eaten something unusual that altered his usual potty regimen. Or, it is possible that your dog has a bladder infection or is even incontinent if he is up in age. Your dog may even be reacting to a recent change in his life -new home, new furniture, new people, new pets, etc. Just remember that these accidents are not your dog's fault and may be isolated incidents. If you suspect a medical problem, be sure to take your dog to the veterinarian. If your dog is incontinent, doggie diapers are one viable solution.

To stop your dog from going potty in the house, begin by allowing him into only one room of your home. You can use baby gates or somehow cordon off that chosen area. Whenever you catch him peeing inside, clap or whistle or make some sort of loud noise to distract him, and quickly take him outside to finish. You may allow him into additional rooms (add one at a time) when he does not soil the area for at least 2 weeks. Once you do allow your dog into additional rooms, if he reverts to the undesirable potty behavior you should go back to one room only for a longer period of time (maybe 3 weeks).

For peeing after coming in from a walk, try keeping your dog outside longer. He may not have had time to finish. You may need to stay out for20 minutes to be sure the job is done.

Always give lots of positive reinforcement (praise, belly rubs, treats) when your dog does go potty outside - let him know you approve!  Discipline just doesn't work well with dogs - they just don't understand it. Intervention, distraction and positive reinforcement works best.

Whenever he pees in the house, be sure to properly clean the soiled area. See 5 Essential Steps To Cleaning Dog Pee .
