Castro Laboreiro Dog

The Portuguese Cattle Dog is one of the rarest breeds in the world, with currently only between 200-500 canines documented. At times, this breed is called a herding dog, however this isn’t his first job. The Portuguese Cattle dog is more of a livestock guarding dog. In this role, he is fearless, intelligent and protects any herd or flock he is given to guard, no matter during the day or at night.

    This hardy breed of canine has a noble and pleasant appearance. The Portuguese Cattle dog is a mastiff type, with a short loin, a deep, oval shaped chest and a strongly built body. His hind legs and forelegs are very muscular and strong. He has a rectangular-shaped head and a long muzzle. The dog’s eyes have a very serious expression which makes him look rather fearsome and unfriendly.

    Good to know

    The Portuguese Cattle dog is still a working breed in Europe, especially in the Azores region. In recent years, the breed almost disappeared, due to modern agricultural farming methods having been introduced. Additionally, many individuals were killed off by farmers accidentally poisoning them instead of the wolves they were targeting. Today, the Portuguese Cattle dog is sometimes employed in the military forces and also as a home companion.
