The Patterdale Terrier is more of a "type" rather than a "breed", being the result of a culmination of working terrier breeds indigenous to the United Kingdom. Patterdale Terrier Type dogs were bred by poachers across northern England. As well as others, for the hunting and dispatch of the red fox in the rocky fells around the Lake District, North West and North East of England where a traditional digging dog was not always of great use. Patterdale Terriers have also been used for Eurasian badger control throughout the UK. The Patterdale was developed in the harsh environment in the north of England, an area unsuitable for arable farming and mostly too hilly for cattle. Sheep farming is the predominant farming activity on these hills. Since the fox is perceived by farmers as being predatory with respect to sheep and small farm animals, terriers are used for predator control. Unlike the dirt dens found in the hunt country of the south, the rocky dens found in the north do not allow much digging. As a consequence, the terrier needs to be able to bolt the fox from the rock crevice or dispatch it where it is found.
