While dog is usually man's best friend, if you have found your dog peeing in your house, then you may be feeling like unfriending him. There are a variety of reasons your dog is soiling inside your house, from behavioral issues like separation anxiety and fear to medical problems. It is necessary for you to understand what is causing your dog to pee inside the house so you can correct the behavior or condition that is causing him to do so.
Make an appointment with your dog's veterinarian. Explain to the veterinarian that your dog usually doesn't urinate in the house, so you need the dog checked to make sure he is healthy. Have the vet examine your dog for such problems as a urinary tract infection. If a problem is found, follow your vet's instructions and give necessary medications to clear up the physical problem that is prompting your dog to urinate inside your house.
Keep notes of when your dog is peeing inside the house and what you were doing at the time. Examine your notes to see if you can detect a pattern of when your dog is more likely to urinate inside the house.
Determine if the action occurs while you're gone, especially for a long period of time. See if your dog exhibits other undesirable actions while you're gone, such as chewing on things or other destructive behavior. If you find this is the case, your dog may be urinating inside the house because of separation anxiety. Stop this behavior by letting your dog out 30 to 40 minutes before you leave, then paying him no attention before you leave. Leave a special treat for him to discover while you're gone. Consider an anxiety medication to calm him if the behavior persists despite your efforts to eliminate it.
Determine if the accident happens during inclement weather. Your dog may urinate during thunderstorms because of fear. Comfort your dog during storms and try to take him out to eliminate before storms roll in. Some dogs learn to urinate in the house during wet weather to avoid going out and getting their paws wet. Supervise your pet during wet weather and schedule bathroom breaks before rain hits to keep your dog from needing to sneak a pee inside.
Clean any urine spots thoroughly to prevent your dog from returning to the spot and urinating there again. Use a specialized formula to remove the urine, and try to clean the carpet padding as well. Failure to get the scent up could also result in your other pets urinating on the same spot.
