Making dogs

Man today uses not all the possibilities of dogs. Our four-legged friends convincingly proved their abilities in various fields of activity.

While they can not replace any machines. There are a lot of examples: from hunting dogs looking for shot animals; from dogs, dragged on drugs, explosives, smelling the smell of criminals on the sidewalks of even the most populous cities, to dogs used in the diagnosis of various serious human diseases.

Dog smelling is their most important quality. It comes to her aid in the very first minutes of life. Barely born puppy is able to find his mother, guided by the smell of milk. Sense provides the dog with basic information about the world. Warns about dangers, indicates enemies, helps to find food and make friends.

The ability of dogs to distinguish odors has long been studied by man, but each time this study has a specific goal. So it’s too early to draw final conclusions about the possibilities of dogs in this area. In addition, it is necessary to take into account differences in the groups of breeds. For example, hunting dogs are difficult to compare with the police. But it is already clear that when using a dog, it is important not only the intuition itself, but also its whole character - with its bad and good sides. Therefore, it is impossible and unambiguously to answer the question of which breed is best used in terms of instinct.

Here you can only build on experience. Without a doubt, when it comes to service dogs, we prefer the shepherd, for example, boxer. However, there are exceptions. Canine professionals still remember how many years ago competitions, in which flair was tested, it was the boxer who won. So the saying about exceptions confirming the rule did not come about by chance. So far it is only clear that among representatives of the same breed in terms of instinct there are significant differences.

But no matter what breed is discussed, the possibilities of a dog compared to a man are enormous. Sniffing the air with the nose, the dog draws in fragments of odorous substances. They reach sensory receptors located in the back of the nose. The dog's nasal apparatus is generally very complex. It consists of many thin ossicles and cartilaginous partitions covered with a mucous membrane. Most of this shell is provided with microscopic odor-sensitive receptors.

We are talking about cells with fan-shaped protrusions that catch fragrant particles. Then the information about the smell in a difficult way is delivered to the brain of the animal.

Let us give some data to compare the capabilities of humans and dogs in the field of distinguishing odors. These data convince us that we will never penetrate the world of flavors in which every normal dog lives.

The area of ​​a person’s nose susceptible to odors is about 5 cm2, and in a German shepherd dog it is about 150 cm 2, that is, thirty times larger. In humans, about 2 million sensitive cells are located on an area of ​​5 cm2, and about 225 million in a German shepherd 150 cm2.
