Businesses in the animal health category help to prevent, identify and manage health problems in domestic animals, livestock and other animals. They may include veterinary practices, animal health product suppliers, laboratories and specialist providers. Depending on the business, customers can expect services such as health checks, diagnosis, treatment, vaccinations, parasite control, routine procedures and advice on caring for an animal's health. Products and support may include veterinary medicines, wound-care supplies, diagnostic tests, nutritional products, supplements and equipment for monitoring or treating animals. Some businesses focus on particular species or needs, such as farm animal health, pet care, dental health or animal nutrition. Veterinary surgeons and veterinary nurses working in clinical roles are regulated through the Royal College of Veterinary Surgeons; the range of services offered by other businesses depends on their role and qualifications.
