Dexter is the smallest type of cow. This cow was bred to be a small size for household living

Dexter cattle are the smallest of the European cattle breeds, being about half the size of a traditional Hereford and about one third the size of a Friesian(Holstein) milking cow. They were considered a rare breed of cattle, until recently, but are now considered a recovering breed by the American Livestock Breeds Conservancy. The Dexter breed originated in Ireland.

The Dexter breed originated in southwestern Ireland from which it was brought to England in 1882. The breed virtually disappeared in Ireland, but was still maintained as a pure breed in a number of small herds in England. The Dexter is a small breed with mature cows weighing between 600–700 pounds (270–320 kg) and mature bulls weighing about 1,000 pounds (450 kg). Considering their small size, the body is wide and deep with a well-rounded hindquarter. Although usually black, a dark-red or dun Dexter is sometimes found. All animals are always solid, with only very minor white marking on the udder or behind the navel. Horns are rather small and thick and grow outward with a forward curve on the male and upward on the cow. The breed is typically a dual-purpose type, although individual herd owners often concentrated on growing either a beef or a milk animal.
