Veterinary medicine is something that helps keep animals healthy and takes care of them when they are sick. When something is wrong with an animal, like a dog or a cat, a veterinarian is like a doctor but they help animals instead of people. They can check an animal's body, give them medicines and do special surgeries if needed. They may also advise pet owners on how to take care of their pet. Taking a pet to the vet can help make sure they stay healthy and happy.
