Animal hospitals and clinics deal with the treatment of animals or pets. They also provide pet training tips, information on pet grooming, as well as immunization of pets from different animal diseases and infections, done by a veterinary doctor. In Appleton, animal hospitals meet stringent professional regulations and are subject to regular inspections of their property and records. Most veterinarian hospitals or clinics in Appleton offer low-cost services at least once a year in conjunction with a local animal shelter or other worthy cause. These clinics are usually just small-animal vaccination opportunities. In Appleton, even some animal hospitals act as rescue groups for a discount program. Most of the rescue groups' members also come to the hospital with their own pets. A few clinics provide free sterilization, vaccination and flea treatment and prevention, with the aid of volunteer animal hospitals. Some registered animal hospitals, work round the clock to respond to emergencies, even provide vets on a 24-hour service. There are some hospitals that treat stray and wild animals that are brought by their field staff, such as inspectors and animal welfare officers.
