A veterinarian is defined as someone qualified and authorized to practice veterinary medicine. They are medical doctors for animals, and have been trained to diagnose and treat disease and injuries in animals. They administer medication, devise treatments, vaccinate, perform surgery, advise on dieting, and provide general health care.
Veterinarians care for companion animals (dogs, cats, birds, rabbits, hamsters, etc.), horses, production animals (pigs, cattle, sheep, etc.), aquatic animals, and even zoo animals. Different veterinarians may specialize in one area or another. For instance, one veterinarian may be an expert on bird health, while another may specialize in canines. Don’t be afraid to ask your veterinarian if they have a specific expertise.
