1. Spay or neuter your pet as soon as possible. Spaying or neutering your pet may stop urine-marking altogether, however, if he has been urine-marking over a long period of time, a pattern may already be established.
2. Restrict your pet’s access to doors and windows through which they can observe animals outside. If this isn’t possible, discourage the presence of other animals near your house
3. Clean soiled areas thoroughly. Don’t use strong smelling cleaners as these may cause your pet to “over-mark” the spot.
4. Make previously soiled areas inaccessible or unattractive.
5. If making soiled areas inaccessible or unattractive isn’t possible, try to change the significance of those areas. Feed, treat and play with your pet in the areas he is inclined to mark.
6. Keep objects likely to cause marking out of reach. Guests’ belongings, new purchases and so forth, should be placed in a closet or cabinet.
7. If your pet is marking in response to a new resident in your home (a new baby, roommate or spouse), have the new resident make friends with your pet by feeding, grooming and playing with your pet. Make sure good things happen to your pet when the new baby is around
8. For dogs: watch your dog at all times when he is indoors for signs that he is thinking about urinating. When he begins to urinate, interrupt him with a loud noise and take him outside, then praise him and give him a treat if he urinates outside. When you’re unable to watch him, put your dog in confinement (a crate or small room where he has never marked) or tether him to you with a leash.
9. Practice “nothing in life is free” with your dog. This is a safe, non-confrontational way to establish your leadership and requires your dog to work for everything he wants from you. Have your dog obey at least one command (such as “sit”) before you pet him, give him dinner, put on his leash or throw a toy for him. Establishing yourself as a strong leader can help stabilize the hierarchy and thus diminish your dog’s need to mark his territory.
10. What NOT to do: Don’t punish your pet after the fact. Punishment administered even a minute after the event is ineffective because your pet won’t understand why he is being punished.
