Why Do Dogs Have Wet Noses? The Science Behind It

Why Do Dogs Have Wet Noses? The Science Behind It

Dogs have wet noses for two reasons. Firstly, they are constantly absorbing information through their nose. This includes scents in the environment and also what you're feeling. Secondly, the wetness helps keep cool by shielding their sensitive webbed paws from the hot ground. Here are some other fun facts about dogs, the ways they use their noses, and why they have them in the first place!

Why Dogs Have Wet Noses

Dogs' noses are not always wet. We cannot simply ask them what's going on, since they do not speak. Dogs and cats' noses are very sensitive, which is why we keep them out of our mouths. As humans, we have certain barriers to smell, and they need to have a way to pick up and sense on things that we cannot. Dogs and cats can not differentiate between various scents, meaning they can smell very similar odors, even if they have never met. Cats, for example, can not differentiate between cats and dogs. They can smell the same odors. They can't smell the difference. Water helps preserve the health of their mucous membranes, while in wet conditions, the dog nose is an excellent indicator for basic health, to prevent ill health conditions.

How Dogs Use Their Nose

Licking is the primary way that dogs communicate with other dogs. The inside of their noses is lined with cilia, which is similar to hairs that allows the dog to gently groom their nose and cheeks. Dogs sniff each other's scents with their nose because they recognize the individual smells they make. In addition, when a dog is playing, they "tickle" their nose against another dog to have their partner blow air into their nose. This is actually pretty fun. Tongue-licking is often used as a friendly greeting between the two dogs. Dogs often lick their tongues on their faces as a greeting, and it can also be a way to identify dominance and position in a social interaction. Dogs may lick their owners as a sign of affection.

The Science of Wet Noses

According to Victoria Stilwell, author of the book The Dog Owners' Handbook, "The reason dogs have wet noses is to cool them down and keep their nose clean." Dogs naturally have a saliva layer that keeps their tongue from sticking to their nose, and "if a dog is hiking and the heat of the day gets too hot for them, it cools the air down in a way that doesn't dry them out." The pups can also smell out changes in the weather, which helps them navigate. "They use their nose and their keen sense of smell to determine the temperature and the amount of moisture in the air," explains Stilwell. When you take your pup for a walk, you can make sure they have adequate fluids and enough fluid retention with these simple steps.

What Else Do We Know About Wet Noses?

Dogs' noses have evolved to work in extreme conditions. Because dogs pant to cool their bodies, their noses are very active, which allows them to absorb huge volumes of scents, particularly from prey. They have three glands in their faces that are active during hot weather. These are called the parasympathetic, sympathetic, and cerebrospinal glands. When these glands are working in response to cold, they signal for the dog to shiver. Because they are not shivering, dogs' bodies stay cool even when they have a hot, wet nose. This may be why dog noses are found in many cold environments, like in glaciers, and can stay at a cool temperature for hours. In some wild animal species, their noses are grown before they are born.


There you have it! The reason dogs have wet noses is because of the natural abilities that God has gifted them with.
