Pottok the Losino, the Galician, the Landais, and the Monchino horses. Tests have revealed considerable genetic differences between populations in the Northern Basque Country and the Southern Basque Country, leading some to consider them separate breeds. Some claim the Pottok's origins derive from the horses on ancient cave paintings in the area and thus claim to descend from the Magdalenian horses of 14,000–7000 BC. Other link its origins to an influx of horses during the Bronze Age. However, neither of these theories has to date been scientifically verified.

Shetland animal breeds dairy and beef. Modern Shetland cattle are usually pied black and white, although other colours were common in the past and sometimes still occur. These cattle are similar in type to other European traditional cattle breeds, and are sometimes used for conservation grazing (the management of natural habitats using grazing animals). Sheep have been kept on the Shetland Isles for at least a thousand years. They are one of the Northern European short-tailed sheep group of breeds, and were regarded as a local type of the extinct Scottish Dunface, which was found throughout the Highlands and Islands of Scotland (and
