He was trained at Purdue University where he obtained his DVM degree. At Purdue, Dr. Whitebone concentrated his studies on small animal medicine and exotics. His special interests were in animal behavior, dentistry, and cardiology.

He routinely performed innovative procedures including laparoscopic surgery, ultrasound, and laser surgery at his former practice. He was a member of AAHA where he learned to practice the highest quality medicine and surgery including the use of advanced pain management measures.
