Castro Laboreiro Dog
dog breed

The Castro Laboreiro Dog (Portuguese: cão de Castro Laboreiro, 'dog of Castro Laboreiro'), also known as the Portuguese cattle dog or Portuguese watchdog, is a dog breed of the livestock guardian type, originating from Castro Laboreiro in the northern mountains of Portugal.
History
The Portuguese name, meaning 'dog from Castro Laboreiro', refers to a small town in the far north of Portugal, now a parish in the Melgaço urban area. It is in the same mountains as the Peneda-Gerês National Park. Although now served by modern highways, the mountainous, rocky area was once quite remote. The modern breed is descended from a very old livestock guardians, which worked with livestock herders in the mountains, defending against wolves and other large predators.
The origin of the breed is not known, although many legends are given. The Portuguese breed club notes that "Everything that is written about their origins is pure fiction, without any scientific or historical accuracy ... data is rare, or does not exist ... most guardian and herding breeds do not have records before 1900".
There are mentions of the Castro Laboreiro in the 19th century but none before 1800.

Why this record matters
The phrase “dog breed” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 8, 2025. The linked authority identifier is Q38099. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1900 and 1800.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
