Scraped, Raw Skin on a Dog's Penis That Isn't Healing
by A reader
Raw, scraped tissue that doesn't heal, with constant licking, may be caused by injury from licking, an infection, an allergy, or less often a growth such as a transmissible venereal tumor or other tumor of the penis. Walking as if something is stuck in the rectum suggests pain around the anus, prostate or anal glands, which may be connected.
Ask your vet for a referral to a veterinary internal medicine specialist or surgeon, or for a biopsy of the area, which is the best way to find out what it is. Keeping a cone on full time is important, because licking keeps reopening the wounds.
Also ask your vet to check his prostate, anal glands and rectum. Please don't give up on him, since many causes are treatable once identified.
