Dogs are very smart animals. Many dog breeds even undertake "various duties", which we usually call "working dogs"! So, do you know how dogs rely on to identify the direction and owner? Next, let us explore the distinguishing ability of dogs!
1. Sense of smell
This is certainly not surprising to everyone. After all, dogs’ sense of smell is famously effective. It is said that it is generally about 40 times that of humans. It can accurately identify some chemicals, avoid harmful gases in the air, and find lost items and people. When dogs eat, they often sniff first to determine whether they can eat. Dogs can not only identify their owners through their sense of smell, but also identify directions, find prey, and find food.
2. Vision
Many people who know something about dogs believe that dogs have poor vision, cannot distinguish colors, and are even color blind. This view is not accurate enough. In fact, dogs can distinguish colors. From a human perspective, the color world of dogs is very strange; dogs have worse eye adjustment ability than humans, but their field of vision is very wide and they can see farther than humans. In addition, their head rotation is very flexible, and they can basically perceive wherever their vision range reaches.
3. Hearing
In fact, dogs have already identified their owners through hearing when they were very young. They record the owner's voice information in their brains and leave a deep impression. From the timbre and pitch of the voice, they can clearly distinguish the owner from strangers; this kind of auditory memory is long-lasting and will remember this information for decades or a lifetime. When hearing the owner's voice in the distance or near, they will immediately distinguish it.
4. Touch
There are many nerve endings distributed in the soles of dog's feet, which can well sense changes in temperature of the outside world and can also sense external information well; when someone moves around, the frequency and number of moves will be recorded to remember this person. Dog fur is also very sensitive, and the way and method of petting by the owner will also be recorded by the dog when touching the skin. Therefore, touch is also one of the ways to identify the owner.
