Thank you for submitting your question regarding Stubby. She appears to have an anal gland abscess that has ruptured. She needs to see her veterinarian. The anal glands sit under the skin on either side of the anus. They are supposed to express fluid every time the dog defecates. However, sometimes they can become infected. When this occurs an abscess forms under the skin, and in her case, has ruptured. It is very painful. She will need pain medication and an antibiotic to treat the infection. She will also need the gland flushed out to ensure it is functioning. In the meantime, do not allow her to lick the area. I hope this information helps!
