A dog is showing his appreciation to his new master by collecting empty bottles for him in Dalian city, Liaoning Province.

Wang, who makes a living by collecting and selling empty bottles, saw the small dog sobbing outside his house one morning in April.

After Wang gave the dog some food and water, it refused to leave and struck with him.

The dog is also a good guard. If anyone takes a bottle from his truck, the dog chases after them and barks until the bottle is retrieved.
