A dog can smell and smell a variety of smells and aromas. The area of ​​the canine brain responsible for the sense of smell is 40 times larger than in humans, and the olfactory receptors range from 125 to 300, depending on the breed. This means that dogs smell thousands of times better than humans.

Knowing such a sensitive sense of smell, people from ancient times used dogs to detect various objects and people. Nowadays, everyone knows that dogs can find illegal substances. But that is far from all. There are other objects and phenomena that can be detected with the help of a dog, only few people know about them. Let's reveal the secret of what it really is.

Emotions

With different physical and mental conditions in the human body, the level of hormones changes, and dogs can easily determine this using their sensitive nose. They perfectly understand when the owner is sad, afraid or unwell. In Western medicine, the term "dog therapist" already exists. Particularly sensitive animals are attacked by people suffering from depression or anxiety disorders in order to help them quickly get rid of these unpleasant phenomena.

Bed bugs

With the development in recent years, the network of bus services, train lines and air transportation bed bugs have the opportunity to travel around the world. The meanness of bedbugs consists in the fact that deep in the night they painlessly bite a person, drink his blood, and then hide in a shelter.In daylight, it is impossible to find them. In some countries, special services have appeared that offer specially trained dogs to detect bugs. Dogs sniff things, furniture or walls of a house and can determine exactly whether bugs live there or not. The services of such agencies are quite expensive, because the accuracy of dog detection of bugs is 96%.

Reagents

Not bad dogs are looking for and water polluting reagents. Animals are trained to find a wide range of flavors emanating from water. They can track the smell if they themselves are in the water, sit in the boat with the owner, or even just go along the coast.

Bacteria

In 1960, a disease was observed in the United States that affected a huge number of bees. However, dogs came to the rescue in the 1970s. It was they who could determine by smelling hives with sick bees that were destroyed so that the disease did not spread further. The thing is that dogs managed to recognize the smell of pathogenic bacteria. Within an hour, the animal can examine more than 100 hives. If a person did the same work, it would take him two whole days. Therefore, the experience of using specially trained dogs is invaluable! Similarly, a dog can be taught to identify fungi and bacteria that cause plant diseases.

Truffles

Most people have heard of truffle mushrooms that grow in the wild underground. It is not possible to grow them in the garden or in forestries, so the price of them is very high. It is the dogs who smell the truffles and dig them out of the ground.Pigs are also used to find mushrooms, but they themselves are not averse to feasting on such a delicacy, so they are not suitable for this. Dogs are more preferred. But, of course, an animal trained to search for truffles costs several thousand dollars.

Diseases

Dogs, as has already been said, can sense a change in a person’s level of hormones. The same can be said about sugar levels. In developed countries, over the past 10 years, dogs have been specially trained to detect epilepsy, cancer, and diabetes in humans. Animals exhibit a unique smell of tumors, low sugar and hormones. They can predict an attack of epilepsy in 10-15 minutes, as a result of which the patient can take measures to protect himself during the attack.

As you can see, a dog’s scent can benefit not only the animal itself, but also humans. You just need to know how to use it correctly.
