Rescue the little dog from man who wants to eat him

We were on our way to work when we spotted a man riding a motorcycle tied the dog behind. Poor little dog's head dangling. We were about to rescue it but he ran away. In the end we managed to chase him into a people's house. He is a dog dealer for people to eat meat. Poor dog. The host is a drunk man who wants to kill the dog. We had to buy other food for him to drink and more money to redeem the dog.
