Video answer: How do you know if it’s too hot to walk your dog…
- A dog’s nose may be able to pick up heat signatures through thermal radiation.
- The researchers published the results of their experiments in the journal Scientific Reports.
- Only a few other animals, such as vampire bats and pit vipers, are known to have this ability.
If you’ve ever booped the snoot of a good boy—and I sure hope you have—you likely noticed his nose was smooth, wet, and cool. But it turns out the tip of a dog’s slobbery, nerve-packed nose—called the rhinarium—may do more than sniff. It may actually detect weak heat signatures.
“It’s a fascinating discovery,” ethologist Marc Bekoff, a professor emeritus at the University of Colorado, Boulder, who was not involved in the study, told Science. “[It] provides yet another window into the sensory worlds of dogs’ highly evolved cold noses.”
A team of researchers from Lund University in Sweden and Eötvös Loránd University in Hungary conducted a series of experiments to test whether dogs could pick up tiny thermal clues about their surroundings. They published the results in Scientific Reports.
First, the teams trained a group of three dogs to select objects that were warmed to about 80 degrees Fahrenheit. (An object set to room temperature was used as a control.) Scientists then covered the objects, which looked indistinguishable from each other, with black electrical tape and placed them about five feet from the dogs. In double-blind tests, the dogs selected the objects that were warmed.
The researchers then analyzed brain scans from 13 dogs who were exposed to “objects emitting neutral or weak thermal radiation,” Science reported. The region in a dog’s brain that connects with its nose (the left somatosensory cortex) lit up when the pups were exposed to the object with weak thermal radiation.
But there was no response in any part of the dogs’ brains that lit up in response to the neutral object. Researchers believe a dog’s rhinarium may be able to sense heat through thermal radiation, in which heat is transferred by shuffling photons.
“The exact mechanism of the thermoreception is as yet unclear,” Anna Bálint, of Lund University, told Gizmodo. “The structure of the dog rhinarium is different from known infrared-sensitive organs, such as the infrared-sensitive pit organs of crotaline snakes, so it may be that the underlying cellular-molecular mechanisms are different.”
It seems dogs have now joined an illustrious group of heat-sensing critters. Some types of snakes, for example, have heat-sensing pits below their eyes that allow them to slither after their warm prey with ease. Vampire bats are the only mammals to have been observed with thermoreception, and they use this sense to find prey whose blood they vaaant to suck.
The black fire beetle uses thermoreception to find conifer forests that have recently burned. The beetles have heat sensors on their legs, which are sensitive to low levels of infrared radiation. They seek out patches of smoldering forest to find food and lay their eggs in charred trees. Most of their predators have either fled or perished in the flames.
In the case of Fido, Fluffy, and Fifi, this sensory superpower may have adapted over time from their ancient wolf relatives. But there’s a lot more work that needs to be done to understand how the sense works, researchers say.

A cold, wet nose is a feature we have all come to expect in a healthy dog. So, when our four-legged friend has a dry nose it can lead to concern that they are unwell and that we need to do something about it. But are we reading too much into this single indicator of poor health? Is the whole ‘wet nose’ issue no more than an urban myth?
Let’s look at what a dry nose is really telling you about your pooch’s health and at how you can decide if you need to get them some help.
How Does a Dog Use Their Nose?
A dog’s nose is a vitally important part of their body. Obviously, they use it for breathing but it also connects to tear ducts in the eye and drains excessive moisture. The sweat glands in the nose help them to cool down on hot days.
It acts as a collection point for all sorts of information from the environment. Messages in the form of chemicals get trapped in the moisture on the dog’s noses. When they flick their tongues over their nose they transfer the chemicals to olfactory glands in the roof of the mouth and the glands interpret what is going on in the outside world. This is why you see the classic ‘sniff, sniff, lick’ routine that your pooch loves so much when you are out for a walk. It also explains how dogs have such a fantastic sense of smell because licking helps them to smell very deeply.
The moisture is a thin layer of mucus mixed with saliva. The mucus is secreted by the nose itself and the saliva is introduced by frequent licking. This may sound a bit gross but it fulfils a vital function! As the moisture evaporates, it helps dogs to cool down in the same way as sweat works on the human body. The moisture is also very helpful for their sense of smell.
Owners often get very worried when they discover that their dog’s nose is dry but the clear message from pet health experts is that there is rarely need for panic. If your dog has no other symptoms, the sensible approach is to wait for 24 hours to see if their nose becomes moist again.
5 Causes of Dry Noses in Dogs
There are several reasons why a perfectly healthy dog could have a dry nose.
1. Nose moisture varies by breed
Some breeds naturally have drier noses. The brachycephalics (which includes Bulldogs and Pugs) often have dry noses and this may be because the shape of their face makes it more difficult for them to lick their nose. Less licking equals a drier nose!
2. Older dogs have drier noses
Puppies have very wet noses! You probably noticed all the little ‘nose prints’ on glass surfaces around your house when your new pup arrived. As a dog gets older, their nose gets drier but this is just a natural change and does not necessarily indicate that they are ill.
3. Sleeping and warm air
A sleeping dog does not lick their nose and this explains why it can dry out. After a long sleep in a warm dry room, their nose can be very dry. Within half an hour, things should be back to normal.
4. Sunburn
Just like humans, dogs can get sunburnt on exposed areas of skin and the tip of the nose is very vulnerable. Dogs with pink skin are most likely to get a sunburnt nose which will feel dry and may peel and crack.
5. Allergies
Dogs can be allergic to pollen, moulds and even some foods. The allergic reaction causes nose redness and swelling. This is usually accompanied by rubbing and scratching of the nose area. Some dogs also react badly to plastic feeding and water bowls, so you could try swapping them for ceramic or stainless steels. Rubber toys will suit them better than the plastic versions. Canine allergies can be treated with antihistamines or steroids prescribed by a vet.
Does Your Dog Need Veterinary Treatment?
If you have ruled out all of the above less serious causes of a dry nose, it may be time to seek professional advice. When your pet has other symptoms, it is always best to play safe and get them checked over by a vet.
Dehydration is serious in all animals and causes a dry nose in dogs. If your dog is not drinking it could be a sign of something serious and it is best to seek advice from a vet straight away. Some auto-immune disorders, such as lupus or pemphigus, cause a dry nose as well as cracking and bleeding. Your vet can make a diagnosis using a combination of blood and urine testing and a biopsy of some tissue on the nose.
Lumps, bumps, changes of colour and bleeding of the nose is always a concern and needs to be checked out quickly.
Treatment for a Dry Nose
Once your vet has ruled out serious health issues, you can help out your pooch with some dry nose remedies. They can be prescribed a moisturising lotion which will hydrate and nourish the skin on the nose and ease discomfort.
As a note of caution, never use your own (human) moisturiser or products that are sold over the counter. They may not be safe for dogs to ingest and constant licking means that your dog will swallow them. Only ever use products supplied or recommended by your vet.
So, there is a quick guide to what is going on with your dog’s nose. The main message is not to panic if a dry nose is the only symptom and to look into potential causes that you can rectify yourself. However, if the dry nose has no obvious cause or is accompanied by other symptoms it is definitely time to get some professional advice.

Have you ever wondered why your dog’s nose is always cold? Well, researchers believe they have found out why.
Scientists in Sweden and Hungary have found that dog’s noses are always cold because they serve as «ultra-sensitive heat detectors» — which is no surprise considering our pups love to sniff out things hiding on the ground. This means that their noses act as super sensors and can sense the temperature of a surface before they’ve touched it. The study found that dogs react to hot objects on their approach towards them, whereas humans would only realise the object was hot once they’ve touched it.
The study disproves the common belief that the only reason dogs’ noses are cold is to regulate their body temperature.
The key findings from the study are:
- Dogs can detect body heat at a distance using the tip of their nose
- Dogs use the tip of their nose to detect heat from five feet away
- When the ambient temperature is 30C, a dog’s end point of the nose is five degrees cooler
- If the outside temperature is zero degrees, a dog’s nose will be around eight degrees
How did they conduct their research?
Researchers from Lund University and Eotvos Lorand University analysed three dogs who were trained to identify the temperature of two objects in the room. The two objects placed in front of the pups were four-inches wide, but one had been heated 12c warmer than the room temperature.
Teresa LettGetty Images
Speaking to the BBC, the researchers said: «All three dogs could detect stimuli of weak thermal radiation in double-blind experiments.
«In addition, we employed functional magnetic resonance imaging on 13 awake dogs, comparing the responses to heat stimuli of about the same temperatures as in the behavioural experiment. The warm stimulus elicited increased neural response.
«All stimuli of radiating heat used in our experiments were too weak to be felt by human hands, even at very short distances. We had to touch the surfaces to feel the warmth.»
So, now you know why your pup’s nose is always cold…

After an especially good belly rub, a dog might bump its nose into its human as a way of saying thanks. Often, this snoot boop feels cold and wet. The owner might wonder: Is it normal for a dog’s nose to feel like this?
The answer is yes, it’s normal. But so is a warm nose, especially after snoozing, said Anna Bálint, a researcher who studies animal behavior at Eötvös Loránd University in Budapest, Hungary. «When a dog is asleep, their nose usually warms up, and it also dries,» she told Live Science. Then, the dog wakes up, gives its nose a lick, and it’s back to cold.
But why are dogs’ noses cold, and could there be a benefit?
Related: Are dogs really smiling at us?
One idea is that the dog’s cold nose could help the furry beast regulate its body temperature. But the nose tip is so small, it’s likely unable to meaningfully contribute to a dog’s overall thermal regulation, Bálint said.
To investigate further, an international team of scientists measured the temperature of many animals’ noses, including a horse, dog and moose. By the time Bálint joined the project, the team had already learned that the nose tips, or rhinariums, of dogs and carnivorous animals are usually cooler than those of herbivores. Perhaps, a cooler nose tip could be an advantage in the wild, the researchers thought.
The team conducted two experiments — one looking at behavior and another at the brain — to see whether a cold rhinarium could make for better heat detection. In the first experiment, the team successfully trained three pet dogs to choose a warmer object, about the same temperature as potential prey, over an object at room temperature. The results indicated that dogs can detect weak thermal radiation from a distance akin to hunting prey.
In the second, brain-centric investigation, scientists presented a box containing warm water and an insulating door to 13 pet dogs trained to lie still in a functional MRI scanner. The dogs’ brains had a higher response when the insulating door was open, revealing the warmer surface, as compared with the neutral one. The region that lit up on the MRI was located in the left hemisphere only. This side of the brain interests scientists because it tends to process responses to food, which in turn has been linked to predatory activity in many vertebrates, Bálint said. The specific region that lit up in the dogs — known as the somatosensory association cortex — helps bring together different sensations such as vision, body position and warmth, she added. This part of the brain combines these senses simultaneously in order to plan an action toward a goal, like targeting an object.
Given that this left-sided neural region lit up when the nose tip was exposed to a warm surface, it’s possible that dogs, and possibly other cold-nosed animals, could be using a heat detection sense along with other senses in their ‘hunting toolbox’ when they’re in pursuit of prey, the researchers said.
Although the recent study, published in February 2020 in the journal Scientific Reports (opens in new tab), is too small to firmly close the case on cold noses, Bálint said a cold nose could be more sensitive to differences in temperature. «People think canines follow their olfaction [sense of smell], which is probably really true,» Bálint said. But windy conditions or stormy weather can make it hard for a working dog to follow scents. «A heat signal could help them.»
So, why is a dog’s nose cold? Bálint and her team continue to search for answers to this question. Now, they’re wondering at what distance this type of heat detection could be useful. For now, only the dog’s nose knows.
