Many pet parents are concerned when their dog pees where they sleep. This behavior may be an indicator of a health problem. A urinary tract infection (UTI), spinal injuries, or hormone imbalances can cause incontinence that leads to urinating during the night. Diapers or potty pads may help control the issue for the time being. If you suspect that your dog has a medical problem, consult with your veterinarian.
Your vet will be able to determine the underlying cause of the behavior. You can also ask for advice on how to address the issues and how to prevent future accidents. For example, using a stain and odor remover on bedding can eliminate scent cues that could prompt your dog to re-mark the area.
In the wild, dogs mark their territory by leaving urine marks in certain places. It's an instinct that helps them mark their den and protect it. This behavior can be difficult to deal with because it can make you feel like your dog is upset with you or trying to send a message.
But it's important to remember that your dog isn't marking your bed because of you. It's an instinct that stems from a desire to keep their sleeping area clean and safe. Punishment isn't the answer if your dog is having bladder issues or exhibiting behavioral problems that are beyond your control. A veterinary exam, blood tests, urinalysis, or X-rays may be necessary to diagnose the issue.
