Nothing feels more like summer than enjoying a delicious ice cream cone. But eating a tasty frozen treat too quickly can create the dreaded brain freeze, changing pleasure into pain. Brain freeze refers to the temporary headache you may experience after eating cold foods too quickly. If you've ever watched your dog eat an ice cube, you may have wondered: Can dogs get brain freeze?
Brain freeze in dogs isn't a scientifically proven phenomenon, but a few signs could signal your dog is experiencing sudden, sharp pains in the head due to eating cold food or certain health conditions. Don't worry — there are ways to let your pup enjoy a nice, cold summer treat without worrying about brain freeze in dogs.
What Is Brain Freeze?
Before answering the question "Can dogs get brain freeze?" it's helpful to know what brain freeze is in the first place. When you eat cold foods, your brain tissue doesn't actually freeze! And even if it did, there are no pain receptors located in the brain, so you wouldn't feel pain.
In humans, a brain freeze is technically called a sphenopalatine ganglioneuralgia. That essentially means "pain of the sphenopalatine nerve ganglion," a bundle of nerves located near the trigeminal nerve that transmits sensory signals from the face. In people and dogs, these nerves are located near the back of the roof of the mouth and are highly sensitive to pain or other changes — most likely to protect the brain from injury.
That brain freeze sensation occurs when the tissue in the back of the mouth or throat is cooled rapidly by something like ice cream. The body senses the cooling sensation and automatically dilates blood vessels to that area, which humans perceive as painful. Once the body senses the temperature returning to normal, it sends signals to constrict the blood vessels, ending the temporary painful sensation.

What Are the Signs of Brain Freeze?
Symptoms of brain freeze in humans include temporary sharp or throbbing pain in the forehead associated with eating cold items too quickly. Since dogs and humans have similar nerves and circulatory structures on the roof of the mouth, it's possible they have similar reactions to gobbling icy treats. But since we can't ask dogs, we don't know for sure. Signs that a dog is experiencing discomfort after eating something cold include:
- Head shaking
- Rapid, violent sneezes
- Drooling
- Pawing or rubbing at their face
- Refusing to eat any more of the cold item
Rapid cooling of the roof of the mouth may also affect the trigeminal nerve in dogs. This nerve affects feeling sensations in much of a dog's face and also governs the motor function of the jaw, parts of the eyes and the area surrounding the eyes. Signs that could indicate your dog is experiencing trigeminal nerve pain or dysfunction include an inability to close the mouth, drooping eyelids and facial paralysis. If you notice any of these signs, it's likely not a brain freeze but a medical condition, so consult with your veterinarian as soon as possible.
