If your dog has been previously house-trained and has recently started urinating in inappropriate places, it is also possible that he may be suffering from a medical condition such as a bladder infection or incontinence.
If you suspect that there may be an underlying medical cause for your dog’s bed-peeing, please consult with your veterinarian.
In the meantime, there are some things you can do to try and stop your dog from peeing on your bed.
One thing you can try is to keep your bedding clean and dry by laundering it frequently. You may also want to consider using a bed cover or placing your bedding in a pet-proofed area.
Finally, make sure that you are providing your dog with plenty of opportunities to urinate inappropriate places by taking him on regular potty breaks and rewarding him for eliminating outdoors.
If you continue to have problems with your dog urinating on your bed, please consult with your veterinarian or a certified animal behaviorist for further assistance.
