A person uses today not all the possibilities of a dog. Our four-legged friends convincingly proved their abilities in a wide range of activities.

While they can not be replaced by any machines. Examples can be given a lot: from hunting dogs, searching for the animals shot; From dogs, trained on drugs, explosives, smelling criminals on the sidewalks of even the most crowded cities, to dogs used in the diagnosis of various serious human diseases.

The smell of dogs is their most important quality. It comes to her aid already in the very first minutes of life. A barely born puppy is able to find his mother, guided by the smell of milk. The flair supplies the dog with basic information about the surrounding world. He warns of dangers, points to enemies, helps to find food and find friends.

The ability of dogs to distinguish smells has long been studied by man, but each time this study pursues a specific goal. So it's too early to make final conclusions about the capabilities of dogs in this area. Among other things, it is necessary to take into account the differences in the groups of rocks. For example, hunting dogs are difficult to compare with policemen. But it is already clear that when using a dog it is important not only in itself a flair, but also all of its character - with its bad and good sides. Therefore, it is impossible to unequivocally answer the question of which breed is best used from the point of view of intuition.

Here it is possible to be based only on experience. Without a doubt, if we are talking about service dogs, we will prefer a shepherd, for example, a boxer . However, there are exceptions. Professional cynologists still remember how many years ago the competition in which the flair was experienced won the boxer. So the saying about exceptions, confirming the rule, arose not by chance. While it is clear only that there are significant differences among representatives of the same breed in terms of flair.

But no matter what kind of breed we were talking about, the possibilities of a dog are enormous compared to a man. Sucking the air with his nose, the dog with him draws in particles of odorous substances. They reach receptive smells of receptors located in the back of the nose. The dog's nose apparatus is generally very complicated. It consists of a set of thin ossicles and cartilaginous membranes, covered with a mucous membrane. Most of this shell is equipped with microscopic receptors, sensitive to odors.

These are cells with fan-shaped projections that capture fragrant particles. Then the information about the smell is delivered in a complex way to the brain of the animal.

Here are some data to compare the capabilities of humans and dogs in the sphere of odor discrimination. These data convince us that we will never penetrate into the world of fragrances in which every normal dog lives.

Susceptible to smells, the area of ​​the nose of a person is about 5 cm2, and the German shepherd - about 150 cm 2, that is, thirty times more. At the person on the area in 5 sm2 it is located approximately 2 million sensitive cells, at the German sheep-dog on 150 sm2 - approximately 225 million.
