- Neuter your dog. Neutering can reduce marking behavior in some dogs.
- Supervise your dog. Keep an eye on your dog at all times, especially when he is near your female dog. This will allow you to catch him in the act of marking and stop him immediately.
- Clean up any accidents immediately. Use an enzymatic cleaner to remove any urine stains from your dog. This will help to prevent your dog from being attracted to the same area and marking again.
- Confine your dog to a specific area. This will help to reduce the number of opportunities your dog has to mark on your other dog.
- Train your dog. There are a number of training methods that you can use to stop your dog from marking. One method is to use a positive reinforcement technique such as clicker training. When your dog does not mark, click the clicker and give him a treat. Another method is to use a time-out technique. When your dog marks, immediately remove him from the situation and place him in a time-out for a few minutes.
- Provide your dog with ample opportunities to go to the bathroom. Ensure take your dog to his designated spot frequently, and be patient and consistent with your training. Eventually, your dog should learn not to mark on your other dog.
