Unit 30 Veterinarians
M: If you like animals and science, you might
want to be a veterinarian. Veterinarians are animal
doctors. They take care of sick and injured
animals. Like doctors, vets perform surgery and give medicine.
When an animal is sick, vets examine it to
find out why. They look for clues in the way an
animal looks and acts. For example, if a dog is
walking in a strange way, it might have injured
its leg. Vets need to observe animals carefully,
since animals cannot speak to tell anyone what
is wrong.
Vets prevent health problems in animals by
giving vaccinations and check-ups and fixing
teeth. They also teach owners how to feed and
train their animals. Vets use special tools to
perform surgery. They fix broken bones, take
out tumors, take X-rays, and treat wounds.
Most vets treat small pets, including dogs and cats. A few vets focus on large animals, such
as sheep, cows, and horses. Large-animal vets
usually drive to ranches and stables where their
patients live. Often, they help when the animals
give birth. Vets who work with large animals
often work outside in all kinds of weather.
A few vets work in zoos and aquariums.
They care for zebras, sharks, and other wild
creatures. Because animals can get sick at any
time, vets often work long hours. Many vets like
their work because they can be with animals every
day, even though sick animals can sometimes bite
or kick their vets.
