German Shepherd (Definite Introduction)

Sensing can be said to be the biggest advantage of dogs. They can not only smell things coming from a distance It is even more difficult to distinguish the smell coming from a dog, so it is very difficult to escape the pursuit of a dog at night. Therefore, dogs are capable of such tasks as search and rescue dogs, drug detection dogs, and police dogs. Their unique senses play a crucial role. Why are dogs’ senses so good? What are the characteristics of dogs’ senses?

The first is the sensitivity to breath. Dogs' ability to sense odor can reach the molecular level. For example, when 1 cubic centimeter contains 9,000 butyric acid molecules, dogs can smell it. When concentrated sulfuric acid is diluted 10 million times, military dogs can still smell it. Dissolve 1 teaspoon of table salt in 500 kilograms of water, or add 1 tablespoon of acetic acid in 500 kilograms of water, and dogs can also smell it.

The second is the ability to distinguish smells. Dogs have a very strong ability to distinguish odor substances. Dogs that have been trained can distinguish the presence or absence of valeric acid in particularly nearby mixtures of propionic acid, acetic acid, suetyl ketone acid, etc., and can distinguish 200 different odors with different concentrations. .

It feels like it occupies a particularly crucial position in the dog's life. Dogs mainly rely on sensory information to identify their owners, determine the gender of the same species, identify their own children and companions, identify roads, kennels, directions, and find prey and food. When dogs are sniffing, they often flap their noses and take shallow short breaths, trying to inhale more gas and enhance their discrimination of objects. For example, when food is thrown to a dog, the dog will sniff it carefully several times before deciding whether to eat it; when meeting a stranger, the dog will always surround him and sniff his scent. Some people say that a dog's survival depends entirely on its nose, and this is not excessive.

It seems that dogs’ senses play a key role in their lives. It can be said that if there is a problem with their senses, the attack on them will be fatal. Therefore, we must pay more attention to the care of their noses during daily feeding.
