As anyone with even a little bit of sense knows, dog noses are simply incredible! They aren’t called ‘a man’s best friend’ for nothing. Their compassion, super abilities, and those puppy dog eyes – they invented the look you know – make them the best companion for anyone. Would it surprise you to know that they are even more amazing than previously thought? Scientists have discovered that dog noses have an ability that we didn’t know about; they can detect body heat. This remarkable skill adds another layer to their extraordinary capabilities, showcasing their evolutionary adaptations that enhance their role as companions and helpers in our lives.
Dogs Have Super Noses
Dog noses are not just remarkable for their scent detection; they are like super sensors that provide dogs with a wealth of information about their environment. A dog’s nose is about 40 times more sensitive than a human’s, allowing them to pick up on scents and signals that we simply cannot perceive. This heightened sensitivity is crucial in various tasks such as search and rescue operations, where dogs locate missing persons, and in detection work, where they sniff out drugs or explosives.
It is extraordinary that dogs can still surprise us with a comic-book likeability that we didn’t even know about. Their ability to sense the emotions of their human companions adds to their incredible nature. Research has shown that dogs can detect human emotions through scent; they can differentiate between different emotional states based on the chemicals released in our sweat and other bodily secretions. This not only makes them amazing companions but also allows them to provide comfort and support when we need it most.
Scientists at the University of Colorado were performing research on canine sniffing abilities when they learned that dogs, and other canines, can detect heat being radiated from animals and humans. This remarkable ability provides them with an edge in various situations, such as hunting and tracking. It also explains why dogs who have lost their sense of hearing and sight are still able to find their way around. Their heat detection capability allows them to locate people even in complete darkness, showcasing their adaptability and instinctual survival skills.
How Dog Noses Sense Heat
We already knew some facts about dog noses; they can detect a dynamic range of smells over long distances. They can do that because, unlike most mammals, dog noses are moist, full of nerves, and colder. The moisture in their noses helps capture scent particles, enhancing their ability to detect different odors. This feature, combined with a much larger olfactory bulb in their brains, allows dogs to not only identify scents but also distinguish between different sources and concentrations of those smells.
Researchers worked with 13 different dog breeds in their research and subsequent experiments. After a bit of training, they learned that when dogs don’t see or smell an item, they can detect heat coming off of it. This heat detection is believed to be an evolutionary trait that has helped canines survive in the wild. For example, tracking dogs can follow a trail by sensing the heat left behind by the animals they are pursuing, making them invaluable to hunters and wildlife researchers alike.
Scientists monitored dogs’ brains in their experiments, and it showed that the area that received feedback from their nose was utilized when dogs sensed heat. It is believed that this fantastic sense was inherited by dogs from wolves that use it for hunting in cold weather. The ability to detect heat is especially beneficial in colder climates where visibility is reduced. Dogs can effectively track their prey during harsh weather conditions, demonstrating their exceptional adaptability and intelligence.

Amazing Dog Nose Facts
Dogs just keep getting better and better, and we don’t just mean their abilities. If you didn’t know about other facts about dog noses, here is some refreshing information: Each unique feature contributes to their capabilities and makes them outstanding companions.
- Dogs can breathe in and out at the same time. We mere humans can only do one of those things at one time, but this ability of dogs is called circular breathing and hastens the air circulation in their body. This unique adaptation allows them to quickly analyze their environment, making it easier to detect subtle changes in scent and temperature.
- Dog noses are designed to detect a myriad of smells. There is a tissue inside the dog nose that splits the air into 2 streams. One is for breathing, and one is for smelling the scents coming in. This separation allows them to continually sample the air while exhaling, maximizing their sensory input.
- Dogs exhibit a behavior called ‘tracking’ where they can follow a trail based on the scent left behind. This skill is not only useful for hunting but also in various dog sports, such as tracking trials where dogs use their sense of smell to locate articles hidden by their handlers.
- The wetness of a dog’s nose is crucial for scent detection. The moisture helps to capture scent particles, allowing dogs to better analyze the smells in their environment. This is why dogs often lick their noses; it’s a way to keep their scent-detecting abilities in peak condition.
- There is a whole lab inside the nose of a dog. Consider this: humans have 6 million receptors in our noses to detect scents. Dogs have 300 million. This is why they can pinpoint smells and follow them from far away distances. Their ability to differentiate between individual scents means they can work in challenging environments, such as rescue missions after disasters where multiple odors are present.
