Veterinarians provide medical care to and look after the well-being of animals. They work in veterinary clinics across the country, handle emergencies when they come up and speak with owners about proper animal care. They usually specialize in small animals (dogs, cats and other household pets) or large animals (livestock, horses, etc.). There are also exotic vets that work for zoos and other conservation organizations in dealing with exotic species.
Some veterinarians work in food safety and inspection or in formulating animal nutrition. The job can be physically and emotionally demanding and all vets run the risk of being scratched, bitten or catching communicable diseases from animals.
