This is Ch. Chik T’Sun of Caversham, 1960 BIS Westminster Winner, the first Pekingese to achieve top dog.
This dog was so radically different from American bred Pekingese that Life Magazine did a story, complete with an X-Ray, to show the American public what exactly was lurking under that massive hair coat.
Giant head, Brachycephalic face, crooked front legs and a crooked spine make up a Westminster Champion. Nice job.
Thanks to Border Wars for digging up the picture.
