Dogs are one of man's most loyal friends. However, whether dogs know their way home has long been a concern.

First, we need to understand the memory and cognitive abilities of dogs. Dogs have a strong memory and can remember information such as their owners' faces, voices and smells. In addition, dogs also have a very keen sense of smell and hearing, which helps them to recognize their surroundings and find their way home. But do dogs really know their way home? Studies have shown that dogs can indeed find their way home in a natural environment. This is because they use multiple senses to recognize cues in the environment, such as smell, hearing, and sight. Dogs can find their way home by sniffing other dogs' urine, smells on the ground, and the scent of their owners. In addition, dogs can also recognize their surroundings through auditory cues, such as the sound of cars, other dogs barking, and so on. However, in an urban environment, dogs may not be able to easily find their way home. This is because urban environments are complex and changeable, and dogs can get lost or disturbed by other factors, such as vehicles, people, and buildings. Additionally, smells and sounds in cities are more complex, which can interfere with the dog's ability to recognize the route home. Therefore, although dogs have strong memory and cognitive abilities, whether they know their way home depends on a variety of factors, such as environment, training, and experience. In urban environments, owners should take care to walk their dog on a lead or use a leash to avoid getting lost or lost. At the same time, the owner can also help the dog better recognize the route home through training and experience.

All in all, whether a dog knows his way home depends on a variety of factors. Although they have strong memory and cognitive abilities, they can get lost or disturbed by other factors in complex environments. Therefore, owners should take care to keep their dogs safe and help them better identify the route home.
