Dr. Sarah Kowalski received her Doctor of Veterinary Medicine from the University of Minnesota College of Veterinary Medicine in 2013, where she focused her clinical rotations on small animal internal medicine and nutrition. After graduating, she completed a one-year internship at a large companion animal practice in Minneapolis before joining a multi-specialty practice in Denver, Colorado, where she worked for seven years.
Her interest in canine nutrition developed through clinical observation: a significant proportion of the dogs she saw for recurrent GI issues, skin problems, and weight concerns had dietary factors at the root of their problems. She pursued additional continuing education through the American College of Veterinary Nutrition and developed a practice specialty in food sensitivity diagnosis, elimination diet protocols, and weight management in companion animals.
She now works as a freelance veterinary consultant, reviewing pet food and treat products, writing nutrition-focused content for pet owners, and providing second-opinion consultations for complex dietary cases. The Liver Treats Lab project focuses on one of the most commonly recommended training treats in professional dog training — freeze-dried beef liver — and provides the specific, practical information that dog owners need but rarely find on product pages.
