Because of the urban transformation, the branch of the pet hospital moved to a new residential area, and the excellent doctor Ma Yuan was transferred to be the person in charge. But Ma Yuan refused again and again, because he was worried that the conflict with his father Ma Lao would escalate, because Ma Lao used to be a security guard in the unit, and he was also a volunteer dog fighter. He has always disliked all kinds of pets, but now he has been actively enthusiastic about social welfare undertakings and is a supernumerary health Committee member of the neighborhood Committee. Lao Ma treats all pet owners unprofessionally, and often has conflicts with Aunt Feng, who loves animals. There are all kinds of visitors in the pet hospital, and there are all kinds of contacts with medical staff such as pony, including misunderstandings and troubles, as well as understanding and communication. Everyone had a positive exchange and beneficial discussion on how to raise pets in a civilized way and coordinate the relationship between people, nature and society. Pony finally reached a communication with his father after a rough time, and became a happy lover with a beautiful pet beautician in Behind the Dark Clouds. The war with Aunt Feng was ups and downs, and finally the dust settled and a happy ending was obtained.
