How to Train Dogs Not to Spray in a House

Dogs can develop a habit of spraying--marking their territory by regularly urinating on vertical surfaces--in the home. This usually happens if dogs are not neutered or spayed, but it can happen if they are, as well. It is a natural behavior and often difficult to stop once a pattern has been established. However, through patience and a consistent re-training program, you can curb this behavior and prevent damage to furniture, flooring and walls. It is important to understand that spraying has nothing to do with house training, but is a behavioral condition.

Instructions

    • 1

      Have your dog neutered or spayed. Hormones are a major contributor to urine marking. Dogs that spray are establishing territorial dominance, whether it be over other dogs in the house or its owners. Having you dog altered will reduce the drive to compete and the urge to spray.

      Assert dominance. Confining your dog to a crate will keep it from spraying, but only while it is confined. Attach a leash to both you and your dog, so that it is in your presence at all times. Forcing your dog to remain with you sends a signal that you are the dominant animal in the pack.

    • 3

      Administer negative reinforcement. Since your dog will be with you at all times, you can catch it in the act and reprimand it. If you see your dog beginning to lift its leg to spray, deliver a stern "no" and make it sit. Immediately follow up with positive reinforcement in the form of praise or food for compliance with your command.

      Begin basic obedience training. Reinforce your position as pack leader by teaching your dog to follow basic commands such as sit and stay. To teach your dog to sit, hold a treat in front of its nose and say "sit." Raise the treat above your dog's head until it looks up and naturally eases into a sitting position. Praise and reward. Stay works the same way. Place your dog in a sitting position, give the command to stay and then back away. Give praise if it stays or put it back in a sitting position if not. Repeat these exercises until your dog consistently obeys these commands.

      Be consistent. Depending on your dog's age and the amount of time it has spent spraying, it can take anywhere from a week to a month or longer before you can leave it alone to wander the house. Until your dog has proven that it can be trusted, never leave it alone where it can re-establish bad behavior. Use a baby gate to block off any areas where your dog has marked heavily, as the scent will urge your dog to do it again.

      Consult your veterinarian about anxiety medication. If your dog's spraying is the result of anxiety, medication can be used during training.
