Thank you for submitting your question regarding your dog. I do recommend having him evaluated. He may have a ulcer or wound there, but there is more serious disease known as a perianal fistula. You will want him to receive treatment and ensure this is not the case. In the meantime, place an E-collar on him if he is trying to lick the area. I hope this information helps!

    It could be an anal gland abscess. This would need to be confirmed then treated by your veterinarian. Typically, sedation is required to lance, drain and flush the abscess. Antibiotics and pain medication are usually dispensed afterwards. An e-collar (cone) will prevent excessive licking.
