You had asked what might cause this -- possibilities include an [anal gland abscess](https://www.petcoach.co/article/anal-glands-sacs-impactions-infections-abscesses-in-dogs), [other infection](https://www.petcoach.co/dog/condition/skin-ulcers-and-draining-lesions/) or possibly a tumor. Unfortunately, without a physical exam, a diagnosis cannot be made. Your veterinarian should be able to diagnose the cause after the exam tomorrow. Until then, place an [e-collar](https://www.petco.com/shop/en/petcostore/product/well-and-good-e-collar) (cone) on your dog to prevent licking or chewing. Any treatment will depend on the diagnosis. It is likely the e-collar will need to be kept on until healing is complete.

    You'll want to be sure to keep the area as clean and dry as possible. If your pet seems irritated you'll want to be sure to prevent any chewing or scratching the area. You may need to pick up a cone collar to help, but be sure not to cover the wound. Your doctor should be able to prescribe medication to alleviate some of the discomfort and prevent any secondary infection. Medical intervention is necessary.

    You had asked what might cause this -- it is possible that you dog has an anal gland abscess or rupture. Unfortunately a mass can also grow in this area. As Crystal stated, best to see the vet tomorrow as you indicated.
