Why is the dog's nose always wet? That's because the dog's wet nose can be contaminated with more odor molecules in the air, and there are many protrusions in the hairless part of the nose. When odor molecules enter the dog's nose, they will complete a series of analysis in the dog's brain. Dog nose is the most intuitive organ to measure the normal body temperature of dogs. A normal dog nose should be moist and cold. In order to keep a keen sense of smell, it is indispensable for dogs to do anything. If the inhaled air is humid, dogs will feel the smell more easily. There are many tiny particles floating in the air, which are the source of odor and will enter the nose with breathing. In order to smell the smell in the air, the tiny particles that make up these smells will be adsorbed on the mucosa in the nostrils. If the mucosa is wet, tiny particles are more likely to be adsorbed on it. So the dog's nose will naturally secrete some water to make it moist. When the weather is hot, they often lick their noses with their tongues to keep them moist.

Why the dog's nose is dry can explain to some extent whether the dog is sick.

Because the dog's nose is wet, it licks with its tongue, so at some point, when the dog is sick, it will have no energy to do this simple action. Just like people are sick, we may wash our faces and brush our teeth because we are unwell, just like dogs are not in the mood when they are sick. Not licking for a long time is one of the reasons why the dog's nose is dry when it is sick. Dog's fever is also a cause of dog's dry nose, because the temperature rises and the nose does not lick, so the nose is easier to dry. There is also a fatal pre-illness symptom like canine distemper, which is also a dry nose and a cracked meat pad with claws.

Under normal circumstances, the dog's nose should be wet and cold. In one case, the dog's nose is dry, but it has nothing to do with the dog's health. That is, dogs don't lick their noses when they just wake up, so they are naturally dry when they wake up. Don't be nervous about it.

Under normal living conditions, the body temperature of healthy dogs is kept within a certain range, usually the lowest in the morning and slightly higher in the afternoon, and the temperature difference between day and night generally does not exceed l℃. If it exceeds l℃ or the body temperature is high in the morning and low in the afternoon, it means that the body temperature is abnormal. The normal body temperature of healthy dogs is 38.5 ~ 39℃ in childhood and 37.5~ 38.5℃ in adulthood. A simple way to judge a dog's fever is to analyze the dog's nose, ears and mental state. The nose of a normal dog is cool and moist, and the skin temperature of the ear root is the same as that of other parts. If the dog's nose (nasal mirror) is dry and hot, the skin temperature at the root of the ear is higher than other parts, the dog is listless, has poor appetite and is thirsty for a long time, which indicates that the dog's body temperature is high. In most infectious diseases, inflammation of respiratory tract, digestive tract and other organs, heatstroke, heatstroke and body temperature rise. In the case of poisoning, severe failure, malnutrition and anemia, the body temperature often drops.

The most accurate way to measure body temperature is to use a thermometer.

When measuring the temperature, the operator throws the mercury column of the thermometer below 35℃, wipes it with an alcohol cotton ball for disinfection, and applies a small amount of lubricant (liquid paraffin). The dog is properly guarded by the assistant, and the thermometer slightly raises its tail and slowly inserts the thermometer into the anus. In order to prevent the thermometer from falling off after insertion, it can be taken out in about 3 minutes and read the degree. When the dog is excited, nervous and exercising, the temperature of the rectum can be slightly increased. Yidu shopping mall
