Girt dog of Ennerdale

The Girt Dog of Ennerdale (also known as the Vampire Dog of Ennerdale or Demon Dog of Ennerdale) was a dog believed to have killed between 300 and 400 sheep over a four-month period in the fells of Cumberland, England, in 1810. The dog was a mongrel, variously described as a "large, brindled, tiger-striped dog" and "a smooth haired dog of a tawny mouse-colour, with dark streaks in tiger-fashion over its hide." Its origins are uncertain, although it was speculated that the dog had escaped from "some gipsy troop" and was perhaps a cross between a mastiff and a greyhound.
The dog was first observed by Thornholme resident Mr Mossop on 10 May 1810, and began killing and eating local sheep shortly afterwards. In September 1810, the dog was shot and killed by John Steel, a resident of Asby. Until the late 1800s, the animal's taxidermied skin was on display in the Hutton's Museum at Keswick, Cumbria.
