This includes pit bulls, Rottweilers,
most other
molosser breeds, and
most of the northern breeds, including huskies, Malamutes, and Akitas.
Due to the remoteness of the various areas of the Pyrenees Mountains and the rest of the region now known as Spain, the original
molosser dogs developed divergently by region into several livestock guardian breeds, the Pyrenean Mastiff, the Spanish Mastiff, and the breed
most closely related to the Pyrenean Mastiff, the Pyrenean Mountain Dog, which is also known as the Great Pyrenees.
