Veterinarian is a very demanding profession; some veterinarians do house calls if they practice in the country. Many vets specialize in different areas. There are three areas that they work in: small animals, exotics and large animals.
Veterinarians who specialize in large animals do their work on farm animals like horses, sheep, cows, and goats. They may specialize in animal orthopedics for large animals.
Veterinarians that treat small animals might treat dogs and cats, guinea pigs, hamsters and other small animals. Veterinarians would offer regular exams, shots, surgeries and so forth. Veterinarians that deal in exotic animals treat snakes, giraffes, elephants, mainly in zoos. They may also have their own private practices and treat exotic pets like lizards and snakes.
Some veterinarians specialize in areas like radiology, oncology or orthopedics. Veterinarians in these specialties usually have their own practices and they offer consulting for vets in general practice.
General practice veterinarians do the following: basic surgeries, well health exams, neutering, vaccinations, setting bones, treatments of bacterial and viral infections, kidney failure.
Like a physician, a veterinarian has to go to school for many years then do residency.
