After the war "there were some extreme examples of repeat matings and some close 'in-breeding'. For instance between Aug 1939 and Dec 1943 Mme J Harper Trois-Fontaines' blenheim bitch Freckles of Ttiweh had seven litters, totalling 39 puppies, by the same dog, namely Plantation Banjo, her own black and tan. Banjo also sired two litters, totalling 13 puppies, by his own daughter, Princesse Celia de Fontenay, in March and October 1943. Another of his daughters, Princesse Bianca de Fontenay, had one puppy by him in Jan 1943. A full brother and sister mating, namely Prince Carol de Fontenay and Princesse Bianca de Fontenay, produced three puppies in May 1944.
It has to be clearly pointed out that close inbreeding such as this should only be practised by breeders with considerable experience and who know their stock's genetic makeup very thoroughly. Whilst there can be advantages, the dangers are considerable. One can understand in those early days in the breed the need to try and 'fix' particular features by in-breeding. Less understandable is the frequent mating of poor Freckles...
