Dr. Burton has published in numerous areas of large animal medicine, especially in the fields of infectious disease and pharmacology. Her current research interests are in the areas of equine pharmacokinetics and the history of large animal veterinary medicine in the context of present-day antimicrobial stewardship and biosecurity. Her current projects include examining the effect of body condition score on the pharmacokinetics of gentamicin in horses.


Dr. Burton is responsible for clinical service in large animal medicine (LAM) at the UW Veterinary Care Large Animal Hospital, working closely with the other LAM senior clinicians (Dr.’s Peek, Holschbach, Breuer, Powers and Kowalski). She is actively involved in the didactic and clinical instruction of veterinary students and with mentoring the UW-Veterinary Care LAM clinical residents.

Clinical Interests

Dr. Alexa Burton has broad clinical experience in large animal medicine, with a strong focus on individualized patient-centered care. Every patient is unique - no single treatment plan fits all animals and all owners! In particular, Dr. Burton has interests in critical care of all large animal species, gastrointestinal disorders and metabolic disease. She also has a strong interest in the medical care and management of older-age large animal species, especially senior and geriatric equine medicine. Additionally, Dr. Burton enjoys working with camelids (alpacas and llamas) and has extensive experience in the advanced veterinary care of neonatal and adult camelids.

Graduate Training

Dr. Alexa Burton received her veterinary degree from the University of Liverpool in the United Kingdom. She completed an internship in large animal medicine and surgery at the Ontario Veterinary College, University of Guelph, Canada. She then went on to a 3-year clinical residency in Large Animal Internal Medicine at Cornell University followed by the 2-year Cornell Clinical Fellowship program. Subsequently, Dr. Burton completed a PhD in Infectious Disease with Dr. Steeve Giguère at the University of Georgia (UGA) College of Veterinary Medicine, while also serving as a senior clinician in Large Animal Medicine at the UGA Veterinary Teaching Hospital.
