plz give me the central idea of the triump of surgery and it should be in 100-120 words

Dear Student,

This chapter tells us how a rich lady pampers her dog and makes it very lazy. She is then worried about it as she thinks it might be sick. Mr Herriott understands the dog's lethargy and treats it at his clinic by giving it proper exercise and monitoring his food habits. The dog becomes active and is returned to its mistress. The central idea of the story is taking care of the pets in a proper way and not pampering them.

Regards
