What is the sense of smell’s features in dogs?

Dogs have a well-developed olfactory organ and are 40 times more sensitive to odors than humans.

According to the measurement, there are 5 million olfactory cells in humans, while dogs have 220 million, and can distinguish more than 20,000 kinds of odors.

The dog’s sense of smell plays an important role in its life. It identifies its owner, identifies its location, identifies the sex of the same kind, identifies mother and child, finds food and prey, and so on, all through the sense of smell.

  • He always smells before he eats, and as long as he smells something strange in the food, he will hesitate or not eat it at all.
  • When a puppy is born, it can neither hear nor see, it relies on touch and smell to determine the location of the mother dog.
  • When the dog touches a stranger, it first circles him and smells him to identify whether the person is familiar. It rubs on the person, both to show friendliness, and to leave a scent on you and classify you as a friend.
  • Male dogs like to leave a little urine in corners, under trees, and other places to determine their territory, and when out for a walk with their owners, they often walk while sniffing the ground, as they search for their mark. The scent secreted by a female dog in heat can travel a long way and attract male dogs to come and mate.
  • If a person has a smell the dog does not like, it will attract its bite. If your dog is sniffing a part of your body from time to time, as if it has a great interest in the new abnormalities there, and even wants to bite that place, then you should pay attention to whether you are sick.

Humans use dogs’ acute sense of smell to train working dogs, police dogs, sheepdogs, hounds, etc. to participate in search and rescue work, helping to find victims buried in snow, desert, and earthquakes.
