Dexter

Cattle

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 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 originates from Ireland.
