The nature of sheep farming (on open moorland) and public rights of access mean that the Maremma is rarely, if ever, used as a livestock guardian in the UK. However, the breed is still used for flock guarding in Italy and has been introduced with success as a livestock guard to the United States and to Australia.

The Coppingers brought Maremmas from Italy, two from working Abruzzi stock and two from Delle Grandes Murailles lines, for their Livestock Guarding Dog Project. Sommerville Sheep farms took stock from the UK (summer, Window and Abruzzi lines) with the aim of establishing a pair of Maremma guardians on each of their fifteen sheep stations in the US. In Australia, Peter and Gladys Cookson imported a bitch in whelp from the Roes in the UK (Sunshoo) and puppies from this litter established themselves successfully as livestock protectors.

Maremmas today guard a whole range of livestock including sheep, goats, donkeys, chickens and llamas! They have proved themselves to be versatile and adaptable, and make loyal guardians and companion dogs. The true Maremma temperament is calm and courageous. There should be no tendency to nervousness or unprovoked aggression.
