Dogs do get dizzy, but scientists do not believe that they get dizzy from chasing their tails…although they are not entirely sure why!
How can dogs chase their tails without getting dizzy? We have gathered everything you need to know, including,
- Why do we get dizzy?
- Why dogs don’t get dizzy from chasing their tails?
- Why do dogs chase their tails?
Why We Get Dizzy
To understand dizziness in dogs, we must first understand why we experience dizziness.
In the inner ear, there is a system called the vestibular system. Our vestibular system gives our body information about our body position, motion, and balance.
Part of the vestibular system is three fluid-filled canals that sit at ninety-degree angles to each other. Each fluid-filled canal is lined with minute hairs and senses direction along one axis. Together these three canals orient your head in three-dimensional space – think of this like the spherical ball compass in an SUV.
As your head moves, the fluid inside the ear moves and causes the hairs lining the canal to move. As the hairs move, nerve cells send a message to the brain, and the brain reads that message as a movement.
When you spin in circles, inertia causes the fluid inside these three canals to pull against the direction of your movement. The hairs inside the canals move in the opposite direction to your spinning.
The fluid inside the three ear canals starts to move in your spinning direction as your body adjusts. The sudden change in the direction of the liquid in the ear canals causes the hairs lining them to stand up straight. Your nerve cells then tell your brain that you have stopped moving, making it look like the world is spinning while you are standing still.
When you stop spinning, inertia keeps the fluid in your ear moving and bends the hairs inside the three canals again. This movement tells your nerve cells, which tell your brain, that you are moving, even though you are not – and this causes the feeling of dizziness!
Why Our Dogs Don’t Get Dizzy From Chasing Their Tails
Dogs have a vestibular system just like humans do, and when something disturbs the balance of their vestibular system, they experience dizziness. Uniquely, however, spinning does not seem to affect a dog’s vestibular system in the same way it does for humans.
People make many assumptions about why dogs don’t experience dizziness after spinning while chasing their tails. The truth is – no one seems to know the answer. Some people dispute the assertion altogether!
Some of the more commonly cited theories for dogs not getting dizzy while chasing their tails include:
- Dogs are lower to the ground.
- Dog’s eyes are positioned differently from human’s.
- When they spin, dogs spin around a central axis, preventing dizziness.
- When chasing their tails, the dog’s eyes focus on one spot, which prevents dizziness.
Dogs Are Lower to the Ground
Some people believe that because dogs are lower to the ground and have a shorter vertical axis, they don’t experience dizziness from spinning. This theory seems a little bizarre since, if true, it would also mean that shorter people experience less dizziness than taller people. As far as we know, nothing has ever proven a correlation between height and dizziness.
Dogs’ Eyes Are Positioned Differently to Humans
The “eye position theory” states that dogs experience dizziness differently than humans because their eyes are on the side of their heads. This is perhaps one of the more ridiculous theories out there since dogs – like humans – have forward-facing eyes!
When They Spin, Dogs Are Spinning Around a Central Axis
Another theory that almost sounds like it could be true if you say it enough times is that because dogs are spinning around a central axis when they chase their tails, they do not experience dizziness.
With a little more thought, however, this theory does not explain a thing! If you have ever been on a roundabout on a playground, you will recall how dizzy you feel after spinning for a while. In this example, the roundabout center is a central axis, and you are revolving around it.
When Chasing Their Tails, Dog’s Eyes Focus On One Spot
Perhaps the theory that seems closest to explaining why dogs do not get dizzy from chasing their tails finds inspiration in ballerinas.
Have you ever wondered how a ballerina can spin in one spot without getting so dizzy they fall over? It is all about where they focus their eyes as they twirl around. As they turn around, ballerinas focus their eyes on a single spot (called “spotting,”) which limits head and eye movements that can contribute to dizziness.
When dogs spin around while chasing their tails, their eyes are fixated on their bottom – a single point of focus. This fixation could explain why dogs do not experience dizziness while chasing their tail but do experience dizziness in other situations.
Which Theory Explains Why Dogs Do Not Get Dizzy Chasing Their Tails
In our opinion, none of the theories above seem to explain the tail-chasing phenomena with certainty. Still, despite hours of searching and more than a few rabbit holes of research, no one seems to have an explanation that holds water in any meaningful way.
Why Dogs Chase Their Tails
While we do not have the inside scoop on dizziness in dogs, we know several things can cause dizziness for our canine friends. These include:
- Ear infections (inner ear or middle ear)
- Idiopathic vestibular disease (old dog vestibular disease)
- Nervous system inflammation
- Nutritional deficiencies (Thiamine)
The conditions listed above cause a physical change in the body and upset the balance of the vestibular system.
Conclusion / Summary
No one can be certain about dizziness in dogs and why (if true) they do not experience dizziness from chasing their tails. However, if we had to back one assumption, it would be the ballet dancer theory!
