History of Herding Dogs and Mastiffs
Thibet Mastiff c 1700
In Eurasia (Asia + Europe) glaciers receded and gave way to fertile forests. Once large dinosaurs had disappeared, stag, wild boar, deer and animals that were the ancestors of today's sheep and goats became more prevalent. Domestication provided both man and dog with a more reliable food source. 'Pile dwellers' could then live in somewhat more permanent settlements like those in the "Fertile Crescent" with dog forming a convenient bond with man. These dogs were used for hunting, as well as guarding the developing settlements. As sheep and goats became domesticated so they formed flocks, these guard dogs were adapted as Livestock Guardians.
