There are a few ways to help a dog stop chasing its tail:
1. Distract the dog with a toy or treat.
2. Give the dog a job to do, like a puzzle or obedience training.
3. Take the dog for a walk or run to help tire it out.
4. Consult with a veterinarian for any underlying medical issues.
5. Talk to an animal behaviorist for more specific advice.
