Italian Greyhound (definite introduction)

We all know about dogs Dogs have a very good sense of smell. They can distinguish more smells than us, and they can smell farther. Moreover, dogs often have the habit of marking when walking, but even so, why can’t a lost dog go home smelling the scent? Let's make some plans on this issue.

The reason why dogs who can go home by themselves rely not only on the smell, but also on a map drawn in the brain by the dog itself. The dog will collect the owner's scent, the scent of other objects on the road, and various visual landmarks (naturally, the dog itself determines which objects serve as landmarks) to build a map in the brain, and once there is a way to find it at a certain moment after getting lost, If you then locate the map in your mind through smell or road signs, the dog will be more likely to return home successfully. Naturally, this also requires the dog to have a concept of "home". Some dogs will think that a certain "geographical location" is their home. This may explain why dogs easily get lost when they move (find their original home). ); some dogs think that their “owner” is their home, which explains why many homeless dogs never get lost.

So it sounds like dogs are not only powerful with their noses, but also have smart brains. Why can’t they still find their way home on their own?

First of all, breath is indeed one of the key factors in leading your dog home, but breath obviously does not stand still and is always there. Under ideal conditions (cold, moist, green, shaded, and windless), the breath can last up to 3 to 4 weeks, and in the average American city, the breath can last up to 3 days. But in domestic places where there are many cars and people, it will be even shorter.

Secondly, most dogs are not equipped to create a clear map in their minds. The terrain in the city is complex and the environment changes very quickly. Every time you go out for a dog walk, the information the dog interacts with is difficult to be the same as the last time. The road is not fixed, and the people you encounter are different from other dogs. In many places, dogs The dog cannot explore. The superposition of these mixed factors makes it an impossible task for the dog to remember the way home.

What’s more important is that when a dog gets lost, not only the owner is anxious, but the dog also realizes that the person it has been following is gone, and the familiar environment is suddenly gone, and fear and fear Anxiety ensues. The sudden anxiety will not make them stop and think about how to find their way home, but will lead them to run around at a loss. This time they run, it becomes more difficult to find their way home.
