If you want to be a legal pet doctor, you must obtain the Veterinary Qualification Certificate of People's Republic of China (PRC). To obtain this certificate, you must sign up for the national unified examination (the annual examination pass rate is 6-8% of the applicants), and you must have a college degree or above in animal medicine, animal husbandry and veterinary medicine and other related majors.

At present, there are no training institutions for pet doctors everywhere. They all get diplomas by studying the corresponding majors in relevant colleges and universities, choose the direction of pet medical treatment according to their hobbies, and then obtain qualifications and go to the corresponding pet hospital for internship study.

I suggest you apply for a five-year animal husbandry and veterinary college or technical secondary school first, then get a college diploma through higher vocational education and correspondence, and then go to the pet hospital to study after learning the corresponding education. Like pets, there is also learning pet grooming, and there is no academic requirement.
