Dog
The dog’s nose has a very sensitive sense and can smell and distinguish a variety of different smells. The reason is that the structure of a dog’s nose is much more complex than that of ordinary animal noses.
Advanced animals regard the nose as a respiratory and sensory organ, so there are wrinkles in the nasal cavity, and there is a layer of mucous membrane on the wrinkles. Through the many sensory cells on these mucous membranes, we Talent distinguishes all kinds of atmosphere.
On this layer of mucous membrane, some mucus often leaks out to moisten these sensory cells, so that the cells can more quickly transmit various smells from the olfactory nerve to the brain.
Puppies also have mucous membranes on their sensory organs, but the structure of a dog’s nose is slightly different. On the top surface of its nose, that is, at the tip of the nose, there is a hairless mucosal structure. Mucus is generally seeped here to allow better protection of the sensory cells. There are many protruding objects on it, which are also its most important sensory organs. Therefore, if you accidentally encounter the puppy's nose occasionally, you will feel wet and sticky. Sticky is caused by the infiltrated mucus.
