It can be funny to watch a dog chase its tail, and usually it's harmless, especially in puppies.
But sometimes it's no laughing matter. While a brief episode of tail chasing is normal for most dogs, there might be a bigger problem if the behavior occurs multiple times a day or lasts for long periods of time.
Dogs sometimes chase their tails when they're in pain. Dogs can develop obsessive-compulsive disorders, just like humans.
In addition, tail chasing can be a symptom of a neurological disease or a seizure disorder. Check with your vet.
Treatments and medications can help your dog once the correct diagnosis is made. Too much tail chasing shouldn't be ignored.
