Nolana Sheep The breeding aim of the Nolana sheep is to combine the advantages of hair sheep with the advantages of native wool sheep. Nolana sheep are hair sheep. They don’t produce wool, but carry a smooth coat during summer and a 4-5 cm (1.6-1.8 in) thick pelt during winter which they shed naturally in spring. Therefore, they don’t need to be shorn.

North Country Cheviot Sheep North Country Cheviots are a "hill breed" of sheep. They evolved on the rugged Scotch highlands and of necessity had to thrive unattended by man and search for food on wild unimproved land. In these conditions the ewes usually lambed alone, and the newborn lambs survived by their near-miraculous ability to get-up, nurse, and run just minutes after their birth.

North of England Mule Sheep This medium- sized crossbred sheep, sired by the Bluefaced Leicester, has a Swaledale or Northumberland type Blackface dam. The latter two breeds are born and reared on the Northern fells and moors and noted for their qualities of hardiness, thriftiness, and longevity. The Mule ewe has the ability to produce and rear prolific crops of lambs under any system.

North Ronaldsay Sheep The North Ronaldsay is a small rare breed of sheep of the Northern short-tailed group of breeds. They have remained virtually unchanged.

The animals are primitive and fine-boned and have evolved in a specialized seashore environment on their native island.
