Why is my dog licking his rear, losing hair, and acting depressed?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Male | neutered | 6 years and 2 months old

My dog keeps licking his rectum to the point he’s losing hair and he is acting very depressed, is there anything I can do until the vet opens in the morning and what could be the cause of this?

Poor Zyyz! His itching can be caused by impacted anal glands (small structures on either side of the anus that make mucus to lubricate the stool), an obstruction, or a food allergy. In my experience, issues with the anal glands are relatively common, especially in dogs who have softer than normal stool. Your vet will be able to express these glands carefully or determine if there is any other cause.
You should definitely have him seen by a vet as soon as you can, as this is pretty uncomfortable. In the meantime, I recommend using an E-colla (or “cone”) to prevent your dog from reaching the area and causing further damage. i hope this helps and that Zyzz feels better soon!
