The most influential breeder in the early days of the Shih Tzu in North America was Swedish-born Ingrid Colwell. Noone has equaled her contribution to the breed. She was the daughter of Ingrid Engstrom.
Mrs. Colwell's original stock was 80 percent Scandinavian. Future breedings incorporated English lines.
