Do Dogs Get Brain Freeze? The Science of Cold Sensitivity in Dogs
9 February 2024 • Updated 7 February 2024
We’ve all experienced a brain freeze, but can our furry friends feel the same thing? While there is no scientific evidence to prove it, the answer is yes. Dogs can get brain freeze. Signs of brain freeze in dogs include restlessness, dilated pupils, and whining. To avoid brain freeze, make sure to give your dog frozen treats one piece at a time to avoid the potential for an ice cream headache.
To find out more about this interesting topic, we will look at research in veterinary science and comparative physiology to explain the physiological processes that cause brain freeze and how they can be applied to dogs.
We will also look at the anatomy and neurology of dogs and how their physiological response to cold is similar to the human experience of sphenopalatine ganglioneuralgia, or brain freeze. By breaking down this information, we hope to give you a better understanding of how your dog reacts to cold treats and how you can make sure they enjoy them safely.

Breaking Down the Brain Freeze: The Physiology of Brain Freeze in Humans and Mammals
The human brain freeze is caused by a sudden cold temperature change in the mouth that leads to the rapid constriction and then dilation of blood vessels. The trigeminal nerve, which is the neural hub of the phenomenon, is activated by this series of events, according to Harvard Health, and sends signals to the brain that are interpreted as pain.
In the larger context of mammalian biology, these reactions are not unique to humans. Because dogs have a similar neural architecture, including the trigeminal nerve, it’s possible that they can feel the same thing. Virginia Tech neuroscientist Kristofer Rau says that the brain is not only a cognitive organ but also a regulatory organ that works to protect the body from temperature changes by regulating blood flow to the face and head.
As a result, the vascular and neural reactions that cause human brain freeze are likely happening in dogs, which means that they probably have their own version of an ice cream headache. A better understanding of the anatomy of a dog’s mouth and throat will help explain how these physiological reactions may be happening in dogs.
Inside the Dog’s Mouth: Dental Anatomy and Oral Sensitivity
The dog’s mouth is a marvel of biological engineering, with a variety of muscles, nerves, and blood vessels that make it possible for dogs to eat, drink, and sense temperature.
The oral cavity is lined with a complex network of muscles, nerves, and blood vessels that enable dogs to eat and drink a wide range of temperatures and textures. According to VIN, the sensitivity of the teeth and their supporting structures, such as the periodontal ligament, to temperature changes could mean that dogs experience a sensation similar to brain freeze.
The oral sensitivity to temperature in dogs is interesting because it suggests that the rapid consumption of cold substances could lead to a brain freeze-like response. The dental anatomy, including the enamel and dentine layers, could potentially conduct cold to the nerves, leading to the sensation of brain freeze.
In addition, a study in PMC by Erin B. Perry found that the oral microbiome of dogs is highly stable over time, even in the face of a variety of environmental factors. This stability suggests that a dog’s oral microbiome is less likely to be impacted by short-term changes, but more research is needed to understand the role of this stability in cold sensitivity and the potential for brain freeze.
When we take these anatomical and microbial factors into account, it’s clear that the next step in understanding the full scope of dogs’ sensitivity to cold is to investigate the neurological side of how dogs experience cold.
Brain Freeze in Dogs: Neurological Responses to Cold
Dogs, like humans, have neurological pathways that detect cold. As one article in Scientific Reports notes, dogs have a highly innervated rhinarium, or nose tip, that is cooler than the surrounding air and densely connected to the trigeminal nerve. This indicates that the rhinarium has a specialized sensory function, potentially similar to the role of the human trigeminal nerve in causing brain freeze.
The somatosensory system in dogs processes sensory information and is known to be activated by a range of stimuli, including cold. Functional magnetic resonance imaging (fMRI) studies have shown that there are brain areas in dogs that are activated by weak thermal radiation.
These areas are part of the somatosensory association cortex, which means that dogs’ brains are equipped to detect cold and potentially experience brain freeze.
It can be difficult to know if dogs are experiencing brain freeze. However, neurological signs like reluctance to eat or drink cold substances, crying, or rubbing the face after consuming something cold could be signs of discomfort similar to human brain freeze.
As researchers learn more about how dogs’ brains work, we will continue to learn more about how dogs’ neurological responses work, which will help us better understand how dogs experience things like cold and, in turn, how they experience pain and other sensations.
How Dogs Experience Pain: Sensory and Pain Perception in Dogs
To determine whether dogs can feel brain freeze, it’s important to understand the complexities of how dogs experience pain. A study in ScienceDirect notes that dogs have been shown to have a complex pain experience that includes sensory and emotional components. This study highlights the multidimensional nature of pain, which is not just a physical experience but also an affective one that can affect a dog’s well-being.
A review in ScienceDirect also notes that it’s important to look at a dog’s behavior to assess pain, as behavioral changes like restlessness or changes in social interactions can be signs of pain. In the case of brain freeze, these behavioral changes could be a sign that a dog is sensitive to the cold stimulus.
In addition, a study in PMC on Cavalier King Charles Spaniels found that dogs have different mechanical sensitivity thresholds that increase when they are in pain. This is important to note when considering whether dogs can feel brain freeze because a dog’s reaction to a sudden cold stimulus could be a sign of a pain response that can be detected through changes in behavior or mechanical sensitivity.
These studies offer in-depth looks at how dogs experience and express pain, which could be similar to the human experience of brain freeze. Dog owners who want to make sure they are taking the best care of their pets should take these pain perceptions and their potential expressions into account.
Preventing Brain Freeze in Dogs
To avoid causing your dog the discomfort of brain freeze, it’s all about portion control. Hill’s Pet explains that breaking up frozen treats into smaller pieces can help prevent the sudden temperature drop that causes the reaction. Meanwhile, We Love Doodles recommends feeding treats slowly and mixing them in with regular treats to help prevent the sudden cold that can lead to brain freeze.
If your dog does experience brain freeze symptoms, like restlessness, dilated pupils, or whining, it’s important to act fast. Hill’s Pet says that you should take the cold item away and gently massage your dog’s head to help relieve the pain. Offering warm water can also help bring your dog’s mouth temperature back to normal and help relieve the symptoms.
Because there are potential risks to very cold treats, like tooth sensitivity or an upset stomach, it’s also a good idea to be mindful of how often you give them to your dog and how cold they are.
In the summer months, Hill’s Pet recommends other ways to keep your dog cool, like making sure they have a place to get out of the sun, fresh water, or even a kiddie pool. This way, you can keep your dog comfortable without the risk of the sudden pain of brain freeze.
In Conclusion: What We Know About Dogs and Brain Freeze
After delving into the details of dog anatomy and the way dogs respond to cold, it’s clear that while there is evidence to suggest that dogs can get brain freeze, more research is needed to say for sure. Our understanding of the canine trigeminal nerve, oral anatomy, and neurological pathways makes it seem likely that dogs would feel a sudden pain similar to human brain freeze when they consume something cold too quickly.
As dog parents, it’s up to us to pay close attention to our dogs’ eating patterns, especially when it comes to giving them frozen snacks. By giving them frozen snacks in moderation and watching them closely for signs of distress, we can help ensure that they don’t experience any pain and that they stay as healthy as possible.
While scientists haven’t yet solved the mystery of dog brain freeze once and for all, their ongoing studies will continue to shed light on the way our canine companions experience the world. Until then, the best way to make sure that our dogs are happy and healthy is to be careful and informed when it comes to feeding them cold snacks.
