Ever since she was a child, Sophia wanted to be a veterinarian, and in 1993, her dream came true. But once out in private practice, she quickly realized that more pets were euthanized due to behavior problems than medical ones. She went back to school to study animal behavior, and earned her Master’s in Animal Science in 2001 from UC Davis where she studied vocal communication in dogs and worked on behavior modification in horses, giraffes, ostriches, and chickens. During this time she was also the award-winning pet columnist for the San Francisco Chronicle. Upon receiving her degree focused on animal behavior, Dr. Yin served for five years as a lecturer in the UC Davis Animal Science Department. Through these and an eclectic collection of other animal behavior experiences, she came to realize the true secret to successful behavior modification.
On Sept. 29, 2014, Dr. Yin passed away. News of her death elicited an outpouring of sorrow in veterinary circles and expressions of profound admiration for Dr. Yin, a superstar in the animal-behavior arena. Whether they knew her personally or only knew of her, veterinarians around the world have said Dr. Yin strongly influenced their practice.
