I was saddened to learn about the sudden death of veterinary behaviorist Dr. Sophia Yin. She made a huge mark on the world of companion animal training and behavior with her writings, seminars and private practice. She was generous, humorous and kind and treated all animals and humans with respect. I worked with her personally on a severe separation anxiety case and I am convinced, without her efforts, Bean probably would not be here today. For all her contributions, great and small, Bean and I say Thank You, Dr. Yin. You will be missed.
