The 7-year-old puppy was left more than 60 kilometers away from home. How did it come back?

Mr. Qiu, a citizen of Hangzhou, lost his dog and came back more than 20 days later. Mr. Qiu was very excited and introduced the dog to everyone. Mr. Qiu's dog is called Doudou. What kind is it? Mr. Qiu himself can't say clearly. According to Mr. Qiu, his dog is not good-looking. Usually I have a good relationship with my father-in-law. I've had it for seven years.

This dog is a very ordinary dog in Mr. Qiu's eyes. He is timid and usually has no spirit at home. I didn't expect special respect for him this time. Mr. Qiu's family drove to their hometown for their holiday. After passing a service area called Tonglu, the whole family got off and rested in the service area. Everyone thought the dog was still lying in the car. After the rest, the family set out again. No one noticed that the dog was no longer in the car. When I got to my hometown, I found the dog missing. Mr. Qiu's father-in-law was very sad after he reacted. After all, he has been raised for seven years and has feelings.

Mr. Qiu drove to Tonglu service area the next morning to look for it. As a result, he searched many times and didn't see Doudou, so he had to drive away again. A few days later, Mr. Qiu came to the service area again, but he still didn't see Doudou. Mr. Qiu was disappointed, but he was helpless and had to walk away disappointed. After the dog was lost, the family slowly accepted the fact of losing peas. Results More than 20 days later, a stray dog appeared at Mr. Qiu's door. Mr. Qiu repeatedly confirmed that it was the lost peas. At that time, peas were dirty and lost a lot of weight. At first glance, I really didn't recognize this as peas.

Mr. Qiu was stunned when he recognized Doudou. Doudou actually came back from 60 kilometers away. This is incredible. At that time, I was driving all the way, and Doudou didn't get off and leave traces. It's a miracle that he can get it back. Mr. Qiu's father-in-law saw Doudou coming back, and his eyes were red with joy. The family quickly brought food to Doudou and cleaned it again. Mr. Qiu felt that his dog was unusual, so he specially consulted dog trainer. Dog trainer thinks that every dog has its own advantages. Some dogs have a strong sense of smell, while others have a good sense of direction. He thinks that Doudou should have an excellent sense of direction in order to find his home from so far away. Mr. Qiu was very happy after hearing this.
