Notice that the Pug below has a bobtail. Renée Willes writes under a Photo of two Happa dogs with bobtails in the book Allt om mops that “reportedly the tails were not cropped but natural bobtails. It still happens today that Pugs are occasionally born with a bobtail” (2006: 112).
The following photo of a Pug is found in the book The new book of the dog; a comprehensive natural history of British dogs and their foreign relatives, with chapters on law, breeding, kennel management, and veterinary treatment that was published 1907.
The picture of the black Pugs below is found on on the front of Mrs. Leslie Williams’ book A Manual of Toy Dogs that was published in 1910.
The below Pug is a stuffed exemplar seen on a postcard from the British Museum. It was owned by Miss G. Bellamy when alive, and stuffed it was owned by the British Museum. Regrettably it was stolen on its way to an exhibition. Note that it is said to be blue.
