Breed History:

The Cão de Castro Laboreiro, also known as the Castro Laboreiro Dog or the Portuguese Watchdog, is an ancient livestock guardian breed originating from the mountainous region of Castro Laboreiro in northern Portugal. For centuries, shepherds relied on these powerful dogs to protect livestock from wolves and other predators in the rugged terrain along the Portuguese-Spanish border.

Developed through natural selection in a harsh mountain environment, the breed became known for its courage, endurance, independence, and unwavering loyalty. It was traditionally used to guard sheep, goats, cattle, farms, and rural properties, often working alone or in small groups.

Today, the Cão de Castro Laboreiro remains one of Portugal's most respected native guardian breeds and is considered an important part of the country's canine heritage.
