The Maremmano-Abruzzese Sheepdog, Italian: Cane da pastore Maremmano-Abruzzese, also called Maremmano, Maremma Sheepdog or Abruzzese Sheepdog, is an Italian breed of livestock guardian dog. It is indigenous to central Italy, particularly to Abruzzo and to the Maremma region of Tuscany and Lazio. It has been used for centuries by Italian shepherds to guard sheep from Wolves . The literal English translation of the name is "shepherd dog of the Maremma and Abruzzo". The English name of the breed derives from that of the Maremma marshlands where, until recently, shepherds, dogs and hundreds of thousands of sheep over-wintered,
and where the dogs are still abundant although Sheep-farming has decreased substantially. It is widely employed in Abruzzo, where sheep herding remains vital to the rural economy and the wolf remains an active and protected Predator .The Maremmano has a solid, muscular build, a thick white coat, a large head and a black nose. According to the breed standard, males should weigh 35–45 kg and stand 65–73 cm at the shoulder, while females weigh 30–40 kg and stand 60–68 cm. Some dogs may be considerably larger. The coat is long and thick; it is rough to the touch, and forms a thick collar around the neck. It should be solid white; some minor yellowing may be tolerated.
Some divide the breed into various subtypes, largely based on small differences in physical attributes and with subtype names based on village and provincial names where the dogs may be found, e.g. the Maremmano, the Marsicano, the Aquilano, the Pescocostanzo, the Maiella, and the Peligno.
However, biologists dispute this division, as well as over-reliance on minor physical differences, as the dogs were bred over the centuries for their behavioral characteristics as flock guardians.
