Description:

'Every Dondo that has been brought to me or that I have received any report of – and Dondos occur sporadically among the Pekingese – is ultimately descended from a certain pair Ah Cum and Goodwood Meh. Five Pekingese – the first to come to England – arrived after the looting of the Imperial Palace in 1860 – one ‘Sooty’ went to Queen Victoria [note: ‘the Queen, I mean’], was kept in the Royal Kennels & never bred from. Schlorff and Hytien went to Lord John Haye, and formed the basis of his extensive kennel. He has bred once a white [2-3] dog with dark eyes & black nose, but never had an albino. The other pair of the 1860 batch Guh & Meh were rich chestnut brown with black masks & points. They were kept going by direct descent at Goodwood till the early nineties without record of albinism. Then 1896, Ah Cum & Mimosa were brought from the Imperial Palace at Pekin by Mrs Douglas Murray, and from the mating of Ah Cum with Goodwood Meh – a descendent of the 1860 Meh – or from his supposed sister Mimosa – all the albinos that I have been able to trace descended. The only rule to avoid an albino Pekingese appearing sporadically in your kennel is to avoid the Ah Cum & Meh stock, or imported Pekingese, who are likely to come from their ancestry.' (ff. 2-3)
