The Bergamasco is calm, watchful and steady, forming close bonds with its household and tending to be reserved rather than hostile with strangers. It tends to weigh up a situation before acting and responds better to cooperation than to repetition. The mats are not brushed out but separated by hand as they form, and take several years to reach full length.
It is a muscular, rustic dog with a large head, a strong muzzle and a tail that hangs low at rest. The coat combines a fine undercoat, harsh outer hair likened to goat hair, and woollier hair that knots with the rest into broad, felted mats over the body and legs, while the hair on the head falls over the eyes. Its colour is mostly grey, from pale to black, and merle also occurs.
The Bergamasco Sheepdog came close to disappearing in the twentieth century, as seasonal droving declined after the Second World War and demand for working dogs fell away. Its revival is credited largely to Maria Andreoli, an Italian breeder who built a breeding programme from the remaining dogs. Bred to move and watch over large flocks with little direction from the shepherd, the breed was expected to think for itself.
