Why Does My Dog Chase His Tail? Play vs Compulsion
We have all seen the cartoons. A silly dog spins in circles trying to catch his own tail. In puppies, this is normal. They are discovering their own bodies ("Hey, this thing follows me!"). But in adult dogs, habitual tail chasing (Whirling) is rarely "just having fun." It is often a red flag for behavioral or medical issues.
1. Boredom (The Most Common Cause)
High-energy working breeds (German Shepherds, Belgian Malinois, Bull Terriers) are bred to work 12 hours a day. If you put a Ferrari in a traffic jam, the engine overheats. If you keep a working dog in an apartment with no job, they develop "stereotypies" (repetitive behaviors) to release anxious energy.
- The Test: If you increase their exercise (flirt pole, running, training) for 3 days, does the spinning stop? If yes, it was boredom.
2. Canine Compulsive Disorder (CCD)
This is the canine equivalent of OCD.
- The Signs: The dog spins for hours. They ignore food, water, and you. They seem to be in a trance. They might spin until they collapse or damage their paws.
- Breeds: Bull Terriers and German Shepherds are genetically predisposed.
- Treatment: This is a brain chemistry issue. It requires SSRI medication (like Prozac/Fluoxetine) and a veterinary behaviorist. You cannot "train" this out of them with punishment.
3. Physical Pain (The "Referral" Itch)
Imagine you have an itch on your back you can't reach. You would squirm. If a dog has pain in their rear end, they spin to try and reach it.
- Anal Glands: Full or infected glands differ pain.
- Flea Allergy: Fleas love the base of the tail. One bite can cause intense itching.
- Neuropathic Pain: An injury to the spine or tail (like "Happy Tail" where they bang it on walls) causes tingling/numbness. The dog attacks the tail because it feels weird.
4. Focal Seizures
Not all seizures involve falling down and shaking (Grand Mal). Some start in a specific part of the brain ("Focal").
- Fly Biting: Snapping at invisible flies.
- Spinning: Sudden, frantic spinning that stops as quickly as it started.
- The Look: The dog looks "spaced out" or confused afterward.
- Action: Record a video and see a neurologist.
5. Attention Seeking
Did you laugh the first time they did it? Did you say "Awww"? Smart dogs learn fast: "Spinning = Mom looks at me and laughs."
- The Test: Do they only do it when you are watching? Do they stop if you leave the room? If yes, it's a learned trick. Ignore it completely to extinguish the behavior.
Conclusion
- Puppy: Normal play.
- Adult: Check for fleas -> Check anal glands -> Increase Exercise.
- Trance-like: Vet (Neurology/Behavior).
