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.

Bulldog breeds Bulldog got interbred with the Old English Bulldog from the 1600s. This breed was bred to guard, hunt and herd. It is a social dog breed with excellent skills for guarding much like the American Bulldog, with a similar body type. This breed is also lesser known than the American Bulldog and the Old English Bulldog. In response to the health problems associated with many short-muzzled dog breeds, particularly the Bulldog, a number of breeders offer alternative bulldogs, some of which are true-breeding lineages, and some are first-generation crosses between two established breeds. Some of these breeders aim to recreate
