were often held in the name of his employer, Sir George Armitage. Dorah was descended in part from animals owned by Thompson's grandfather Commissioner Thompson at the beginning of the century, as well as a Mastiff of the Bold Hall line (recorded from 1705), a bitch purchased from canal boat men, another caught by Crabtree in a fox trap, a dog from Nostal priory and another dog from Walton Hall, owned by the naturalist, Charles Waterton. J. W. Thompson's first stud dog, Hector, came from crossing a bitch, Juno, bought from animal dealer Bill George, to a dog, Tiger, owned by a Captain Fenton. Neither of these had any pedigree, as was normal for the period. Between 1830 and 1850 he bred the descendants of these dogs and some others to produce a line with the short, broad head and massive build he favoured. In 1835, T.V.H. Lukey started his operations by breeding an Alpine Mastiff bitch of the Chatsworth line, Old Bob-Tailed Countess (bought from dog dealer Bill White), to Pluto, a large black Mastiff of unknown origin belonging to the Marquis of Hertford. The result was a bitch called Yarrow, who was mated to Couchez, another Alpine Mastiff belonging (at the time) to White and later mated to a brindle dog also in White's possession. Lukey produced animals that were taller but less massive than Thompson's. After 1850, Thompson and Lukey collaborated, and the modern Mastiff was created, though animals without pedigree or of dubious pedigree continued to be bred from into the 20th century. Another important contribution to the breed was made by a dog called Lion, owned by Captain (later Colonel) John Garnier of The Royal Engineers. He bought two Mastiffs from the previously mentioned dealer Bill George. The bitch, Eve, bought by George at Leadenhall Market, was old enough to be grey-muzzled, but of good type. The dog, Adam, was of reputed Lyme Hall origin, but bought at Tattersalls and suspected by Garnier of containing a "dash of Boarhound", an ancestral form of Great Dane. Garnier took them with him when he was posted to Canada and brought back their puppy, Lion. He was bred to Lukey's Countess to produce Governor, the source of all existing male Mastiff lines (Lion was also mated to Lufra, a Scottish Deerhound, and their puppy Marquis appears in the pedigrees of both Deerhounds and Irish Wolfhounds).
