That depends on what you like. If animals are your passion and you love working with them then yes.You can center your entire career around animals. But also study what kind of income you might make and what's involved in going into an animal profession whether it be dog grooming, animal training, dog sitting or pet sitting, or veterinary medicine. Course if your goal is to become a veterinarian, that's going to take a lot of work, good grades, an excellent background work experience. So good luck in your endeavors.
