Dr. Chris Newton with a patient during a farm call. Dr. Newton is one of the ambulatory, or field, veterinarians at Rood & Riddle Equine Hospital. To say he's busy is an understatement. The iconoclastic doctor and champion equestrian (who meditates and yet is also addicted to his Blackberry) specializes in reproduction, but does a multitude of other things: lameness treatment, physical therapy, acupuncture, chiropractic, and special projects such as consulting on the design of a prosthetic hoof.
