The Rat Terrier is an American dog but was created from a mix of Fox Terrier, Beagle, Manchester Terrier, Old English White Terrier, Toy Fox Terrier, Italian Greyhound and Whippet. From 1910 through to the 1930s, he was among the most popular farm dogs and was used to hunt, catch rats and other creatures and other farm work. He can hunt below and above ground equally well and deal with vermin, rodents and small game.

His coat colour can be any type of pied patterns. Pied is when large coloured patches are mixed with white.
