Have you ever heard a puppy cry?

It has a white hair, soft and fluffy; A big head with two ears on it; A pair of long, thin feet that run like a whirlwind. It has a good temper. Every time he sees other dogs getting angry, he will obediently run away from them and not fight with them. The dog is very active, its favorite is running, every day WHEN I go to the yard running, it will always follow me behind to accompany me to exercise. Once, I took him for a walk, and a man tried to grab him, but he ran out and scared him away.
