What a precious photo this is!! I have a number of photos of The Prince and Princess with this charming chow which I will be adding to this page as I get them scanned in . This particular image is an original 1940’s 8×10 photo I acquired with all the info written on the back. Such a treasure trove of Royal and Chow history all in one photo.
The image below was also from 1940 and I would imagine taken at the same time as the above photo as they are wearing the same clothing
The Duke of Kent (late father of the present Duke) gifted his daughter, Princess Alexandra, first cousin to the Queen, a superb chow chow, who boasted the elegant pedigree name of Choonam Li Wu T’song, but was always called by the young princess by it’s pet name Mouff (pronounced Muff)
