Jin Mao was only one month old when he first came back, but this kind of dog is big and grows very fast. When he first arrived at our house, he ran around, smelling here and there, and suddenly ran to the rich tree and jumped on it during the Chinese New Year. Almost five months later, he was very old and stood as tall as I was then. Once my family went out, and I was the only one who took him out to play. I was running with him when I heard a dog barking, which was similar to the barking of a golden retriever. Our Pan Pan also cried at once. When crossing the street, I saw the owner of another golden retriever pulling him. When they meet, it's like seeing their family. Because they are both retriever, they have known each other since then.
