Tom Horner says in his book "Terriers of the World" that without no doubt the Dandie Dinmont was used to shorten the legs. The Cheshire Terrier, a small Bull Terrier was probably used for gameness. But here again there is disagreements among the historians. Sir Jocelyn Lucas, who kept , bred and worked with Sealyhams for many years , suggests in his book "The new book of the Sealyham" (1929) that the white, smooth-coated breed known as the Cheshire Terrier was the natural choice for Mr Edwards to use. It had the points he wanted and lived fairly close by.
