Dr. Robert Duquette


Associate Director,

Veterinary Professional Services West Area

Dr. Robert Duquette is the Associate Director of the West Zone for Merck Animal Health Veterinary Professional Services. He earned his PhD in veterinary physiology and doctorate degree in veterinary medicine, from the University of Liverpool in England. During his graduate studies, he lectured and tutored in the university’s veterinary, medical, and dental faculties. Dr. Duquette then practiced companion animal medicine, surgery, and shelter medicine for 10 years in both the United Kingdom and United States and served as the head veterinarian for a large municipal shelter in California.

In November 2014, he joined Merck Animal Health and was appointed Senior Technical Services Veterinarian for the Northern California and Pacific Northwest regions. Dr. Duquette has authored and co-authored papers, publications, and book chapters, and has presented his work at numerous conferences in Europe and North America. His practice interests include dermatology as well as preventative and shelter medicine. Dr. Duquette is a member of the American Veterinary Medical Association, California Veterinary Medical Association, the American Academy of Veterinary Pharmacology and Therapeutics, and PrideVMC.

“It’s an honor to be part of such a diverse and talented Team. Not a day has gone by that I haven’t learned new and exciting innovations across the veterinary field – not only in companion animals, but for all animals.”

Prior to his work at Merck, he served as senior veterinarian at a municipal shelter in California, where his team decreased the prevalence of canine parvovirus and infectious diseases overall, and drastically reduced the euthanasia rate.

Dr. Duquette believes that Merck is an incredible company on many levels: the quality of leadership, its research capabilities, charitable giving, and the message it conveys internally as well as to the public.

Outside of work, Dr. Duquette enjoys gardening, photography, and spending time with his family and many rescue pets; he is also a supporter of animal rescue organizations. When time permits, Dr. Duquette also volunteers as a supervising veterinarian at student-run veterinary clinics that serve underprivileged communities in Northern California as well as being a voluntary veterinarian for the Street Dog Coalition.
