Why do dogs bite their tail? Dogs may be trying to relieve their anxiety and stress. Some dogs may feel anxious, such as lack of social interaction or changes in background environment, which may be due to concerns.

1. Bored

If the dog is always at home alone and no one plays with it, it will chase its tail and bite it while spinning around to kill time. This situation often occurs in puppies. The owner can prepare more toys for the dog and spend more time to play with the dog so that the dog will not feel bored.

2. Suffering from skin diseases

If the dog's tail has skin diseases, due to the strong itching, the dog will frequently chase and bite itch. The owner can open the hair on the dog's tail for examination. If you find symptoms such as redness, swelling, dander, and hair loss, the dog may have a skin disease and needs to consult a pet doctor in time for medication treatment.

3. Anal glands are blocked

If the dog's anal glands are not cleaned for a long time, resulting in anal blockage and the dog feels discomfort around the anus, it will cause tail biting, anal licking, and butt grinding. Therefore, the owner needs to clean the anal glands of the dog regularly to avoid blockage.

4. Obsessive-compulsive disorder

Some experts have studied that some dogs with obsessive-compulsive disorder will deliberately bite their tails, hoping to attract the attention of their owners. At this time, the owner can try to distract the dog and increase the dog's exercise appropriately to see if it will be effective.
