1. The structure of the dog's nose

A dog's nose is not only an external organ, but also has an extremely complex internal structure. In dogs' nasal passages, there are plenty of nasal hair and cilia that help dogs filter out airborne particles and prevent them from entering the esophagus and lungs. In addition, dogs also have a large number of olfactory receptor cells in their nasal cavity, which can sense chemicals in the air and relay this information to the dog's brain through the nervous system.

2. The dog's sense of smell

Dogs have an excellent sense of smell, far surpassing those of humans. Dogs have a much more number of olfactory receptor cells on their noses than humans and can sense odors at very low concentrations, and the dog's olfactory system can classify, recognize, and remember odor information. As a result, dogs can use their sense of smell to identify humans, other animals, and objects, and even use their sense of smell to detect potential diseases.

3. The nose of the dog and the breed of the dog

Different breeds of dogs also have slightly different nose morphology and function. For example, dogs with small, flat noses (such as hunting dogs, ghost-faced dogs, etc.) have relatively weak olfactory ability due to short noses, while dogs with long noses (such as greyhounds, greyhounds, etc.) can use their olfactory abilities better. In addition, factors such as the color of the dog's nose, humidity, and temperature can also affect the dog's sense of smell and health, which requires daily attention and protection.

4. The importance of the dog's nose skin wheel in the dog's life

A dog's nose plays a vital role in a dog's life. A dog's nose can help dogs track prey, find humans, identify burning items, and perceive their surroundings.

2. A dog's sense of smell is more than 1 million times more sensitive than that of a human. Years of town.

3. Dogs have a larger olfactory area, and there are 40 times more brain cells related to smell in the brain than humans.

4. The tip of the dog's nose is kept moist by special secretory cells, and the smell is seen as particles, which will dissolve into the nasal fluid and then bring it to the sensory cells.

5. Dogs generally breathe through the nose, and only breathe through the mouth in hot weather or after exercise.

6. Short-nosed dogs, their oral soft palate is squeezed backwards and close to the head of the larynx, so that the mouth breathing is not smooth.

A dog's sense of smell is about 1,200 times that of a human.

The structure of a dog's nose is much more complex than that of a general animal's nose. Among the higher animals, they use the nose as an organ for breathing air, and also as an olfactory organ for smelling.

There are only 5 million olfactory cells in the human sense, covering a small part of the mucosa in the upper part of the nasal cavity, with an area of only about 5 square centimeters; The olfactory cells of dogs are about 125000 200000, and some breeds have more number, for example, the olfactory cells of a kind of Mushan Song Shepherd Dog have 2200000 olfactory cells, and these olfactory cells occupy an area of about 150 square centimeters in the nasal cavity.

Dogs are a very common canine mammal and the most frequently kept pets.

According to United Nations statistics, the total number of dogs in the world is about 600 million, and there are about 200 million in China. Dogs are the earliest domesticated animals of man. Enlarge.

Dogs' noses are usually damp, because they have a lot of sweat and mucus glands on their noses, and when they breathe, they will vacuumize the odor molecules in the gas and attach them to the mucus, which is one of the reasons why dogs have a particularly sensitive sense of smell.

In addition, the surface of the dog's nose also has a lot of folds and bulges, which can increase its surface area and the number of odor receptors, or further enhance its olfactory sensitivity. Some dog breeds also have a specific shape of nose, for example, the greyhound has a slender and towering nose, and the bull terrier has a flattened and broad nose.

2. The olfactory characteristics of the dog's nose

Dogs' sense of smell is extremely sensitive, broadly speaking, it can be used to find, identify and track odors, canines have a nose bridge more than 20 times larger than humans, there are millions of olfactory receptors in the nasal cavity, they can sniff out very low concentrations of odors in our living environment, and can even identify hundreds of odors, which is why dogs are widely used in security, search and rescue and other fields.

In addition, dogs can distinguish species, sex, health status, mood and behavior by smell. For example, when a dog gets to know a strange dog, it will first sniff its excrement and urine and other secretions to find out if the other person is of the same species, gender, health status, and whether it is the first time they have met.
