A Dog. A man brings a dag with him saying furiously to the boss of a pet store:"you sold this dog to me for the aim of watching door, but it without barking a sound when a thief came in my house and stole 300 RMB from my house!" The boss rolled his eyes and said:"the previous owner of the dog is a multimillionaire; 300RMB was not in its eyes." Please correct my sentence if there is a problem.
