The Special Functions of a Dog’s Nose
📝 Summary
A dog's nose does far more than smell: it works like a GPS for navigation, a living thermometer for testing food temperature, and a unique fingerprint via its nose print. It also drives appetite and greets other dogs, so protect this sensitive sense from strong artificial scents.
1 What Makes a Dog’s Nose Special
1. Wet and dry nose
Generally, dogs lick their noses often to keep them moist, and they are only dry right after waking. But if you notice the nose is frequently dry, it may signal discomfort—such as heat, a cold, or illness—and you should take the dog to a vet for a check-up.
2. Nose-to-nose
When we see dogs touching noses, the scene looks especially affectionate. You may also see a dog sniff another dog’s body and rear—this is actually how dogs say hello!
3. Like a fingerprint
If human identity relies on fingerprints, dogs rely on their nose prints. A dog’s nose print is unique—your dog at home is one of a kind too!
4. Built-in GPS
The most remarkable feature of a dog’s nose is its GPS-like ability: dogs use scent to navigate to where they want to go. For example, they can smell out and find the tasty treats their owner has hidden.
That said, owners should realize that modern life is full of synthetic chemicals—artificial fragrances and the like release scents that can affect a dog’s sense of smell and cause it to decline.
5. A living thermometer
A dog’s nose works like a flesh-and-blood thermometer. Before eating, a dog sniffs to gauge temperature and avoid burns—unlike some owners who are careless and burn their own mouths.
6. Gathering information
Dogs often use urine to mark territory. Their nose tells them whether someone (or some dog) has invaded their space, and it can detect the scent of a dog in heat. When a dog smells a dog in heat, it may try to escape the house or urinate indoors, so owners should pay attention to this.
7. Affecting appetite
Dogs are not very sensitive to taste and cannot really tell sweet, sour, bitter, or spicy. A dog’s appetite is usually driven by what it smells, so when a dog is sick—especially with respiratory infection or a stuffy nose—it loses interest in food. Because dogs are sensitive to smells, they dislike strong odors, which make them uncomfortable or even distressed!
So owners should avoid spraying perfume at a dog, and use fewer strongly scented items like air fresheners at home, to protect the dog’s sense of smell.
Understanding these points gives you a fresh appreciation of the dog’s nose and the secrets it holds.
