In addition to completing undergraduate training and four years of veterinary school, Board Certified Veterinary Specialists are similar to their human medical counterparts in that they have completed an internship and residency in their specialized field (an additional 3-5 years training). Specialists bring a greater understanding in the area of internal medicine, cardiology, oncology, or neurology, and have a greater knowledge of the unusual, the uncommon, or rare. In addition, a Specialist may have diagnostic equipment not generally used by a general practice veterinarian.
