Why Do Dogs Chase Their Tails? Understanding This Common Canine Behavior

Dogs are full of funny quirks, and one of the most classic is tail chasing. It's easy to laugh when your pup spins in circles, trying to catch their own tail. But sometimes, this silly behavior has a deeper meaning. Let's explore why dogs chase their tails and when it might be more than just play.

Is My Dog Just Being Playful?

Many dogs chase their tails out of boredom or as a way to burn off energy. This is especially true for dogs left alone for long periods or those without enough mental or physical stimulation.

Try This:

• Add daily walks or play sessions to tire your pup out.
• Use puzzle toys to keep their brain busy.
• Swap tail chasing for a game of fetch or tug.

Most dogs would rather chase a ball than their own tail—they just need the chance!

Tail Chasing by Age: Puppies and Seniors

Puppies:

Young dogs often chase or bite their tails simply because they’re discovering their bodies. It’s harmless and usually fades as they grow.

Older Dogs:

If your senior dog starts chasing or chewing their tail, it might be a sign of cognitive decline. Repetitive behaviors can point to aging brain changes. Talk to your vet if this is new behavior in an older pet.

Is It for Attention?

Dogs love our attention—even the negative kind. If you laugh or scold them when they chase their tail, they may keep doing it just to get a reaction.

What to Do:

• Ignore the tail chasing.
• Praise calm, non-chasing behavior instead.

By flipping the script, you teach your dog that spinning doesn't equal attention.

Could There Be a Medical Reason?

Tail chasing can also signal discomfort or pain. Dogs often lick, bite, or chase their tails to soothe irritation.

Medical issues to consider:

• Tail injury from bumping into something
• Fleas or food allergies causing itchy skin
• Worms like tapeworms exiting the rectum
• Impacted anal glands
• Nerve damage or neurological issues

If your dog suddenly starts biting or chasing their tail, schedule a vet checkup. Your vet can treat infections, evacuate anal glands, prescribe allergy meds, or rule out nerve problems.

What About OCD or Anxiety?

Tail chasing can also be a compulsive behavior. Dogs with anxiety or obsessive-compulsive disorder (OCD) may spin or chew their tails repeatedly.

Possible triggers:

• Separation anxiety
• Overexcitement (like seeing a bird or visitor)
• Lingering habit after a past injury

What Helps:

• Watch for what sets off the tail chasing
• Distract with another activity before it starts
• Use calming tools like behavior training and medication (your vet can help)

Some dogs respond well to medications that regulate serotonin or dopamine, especially when combined with training.

When to Worry (and When to Call the Vet)

Tail chasing can start off funny but turn into something harmful. If your dog injures themselves, chews nonstop, or starts chasing their tail more often, it’s time for help.

Your vet can get to the root of the problem—whether it's medical, emotional, or both. The sooner you find out why your dog is chasing their tail, the sooner you can help them feel better.

Final Woof: Next time your pup starts spinning in circles, smile—but also take a moment to observe. Sometimes tail chasing is just play. Sometimes it's a sign they need a little extra love, attention, or care.
