Portuguese Cattle Dog

Dog breed · Portugal

Overview

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.

Appearance

Appearance: The standardised appearance for which the Castro Laboreiro Dog has been bred is somewhat wolf-like in outline. It is a large dog, but not oversize. Height should not be above 60 cm (24 in) at the withers and weight should not be more than [dose — ask your vet] (88 lbs); females somewhat smaller. Coat colours are often described in wolf terms: "dark wolf colour", "light wolf colour". Most breeders prefer what is considered the most authentic, called "mountain colour" (cor do monte), also described as similar to the coat of a wolf, but a mixed light and dark grey interspersed with individual hairs (not spots) that are brown (called "pine-seed") or dark red (called "mahogany"), forming overall a brindle pattern.

Health

Health Issues: Health issues specific to the breed have not been documented. Dogs represented as Castro Laboreiros may be mixed with other breeds, which may have other genetic health problems. Puppy buyers should enquire of breeders about types of health testing done on the sire and dam; responsible breeders will be able to provide information. Being a "rare breed" does not guarantee immunity from inherited disease or disability.

History

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. Camilo Castelo Branco in his novella A Brasileira de Prazins (1882) mentions "the dogs of Castro Laboreiro, very fierce ..."
