Dogs looking for home is to rely on the scent map in the mind enough to come home on their own dogs can come back relying on more than just the scent, but also a map drawn by the dog in his own mind. Dogs will collect the owner’s scent, the scent of other things on the road and a variety of visual road signs (of course, the dog itself to determine which things as road signs) in the mind to build a map, once lost at a certain moment there is a way to reposition themselves through the scent or road signs back to the map in the brain, the dog is likely to go home. Of course, this also requires the dog to have a concept of “home”, some dogs will think that a certain “geographic location” is his home, which can explain why the dog will easily get lost when moving (to find the original home); some dogs think “This explains why many stray dogs do not get lost. The city is filled with a variety of smells that affect the dog’s sense of smell every day, so it sounds like the dog not only has a great nose, the brain is also very flexible, why can not find their own home? First of all, scent is indeed one of the key factors in guiding a dog home, but scent obviously doesn’t stand still and stay there. Under ideal conditions (cool, humid, shady and windless), scent can last up to 3 to 4 weeks, while in a typical city, it can last up to 3 days. And in places with many cars and people, it will be even shorter.
Modern urban environments change quickly and routes are difficult to remember Secondly, most dogs are not equipped to form a clear map in their heads. The terrain in the city is complex, the environment changes very quickly, every time you go out to walk your dog, the dog is exposed to information that is hardly the same as the last time, the route is not fixed, the people you meet and other dogs are different, and many places the dog can not explore, the superposition of these complex factors makes the dog remember the way home becomes an impossible task. Lost dogs will be dominated by fear, more difficult to find the way home More importantly, when a dog is lost, not only the owner is anxious, the dog will also realize that the person they have been following is gone, suddenly the familiar environment is gone, panic and anxiety ensues, the sudden anxiety will not make them stop and think about how to find the way home, but lead them to run overwhelmed, this run, it is more This running makes it more difficult to find the way home.
