Sometimes, we think of veterinarians as being the poor cousins of doctors. Most of them are driven by a passion for taking care of animals, and passion projects rarely bring in big money. You'll know from your own insurance and medical bills that treatment and surgery for animals cost a lot less than treatment and surgery for people, so how is it that some veterinarians are earning more than doctors?
The answer lies in the 'research' side of the industry. A research veterinarian will have years of experience, and a scientific understanding of medications and treatment programs. Only those with a Doctorate in Veterinary Medicine need apply for this role, as well as the mentality to cope with the potential consequences of attempting experimental procedures on sick animals. Several years of hands-on experience as a regular vet are needed before you can even consider reaching for greater heights.
