  • Not well suited to apartment living : His size, his territory and his need for space make urban life difficult for him.
  • Socialization is essential : His natural wariness toward strangers must be channeled early and seriously.

Origins

Where does it come from?

The Mâtin de l'Alentejo is an ancient Portuguese guard breed, traditionally used to protect herds and farms in the plains of Alentejo. According to various sources, it is said to descend from molossers that came from the Middle East. Its courage, its frugality and its great reliability have forged its reputation as a rural protection dog. The breed is recognized by the FCI in group 2 under number 96 since 1954.

Appearance

What does it look like?

The Mâtin de l'Alentejo is a large-sized dog, powerful, rustic and well muscled, whose body fits into a rectangle. The topline is straight, the chest is well let down and the head, massive without excessive heaviness, remains proportionate to the whole. The coat is short to medium-length, thick, dense and smooth. The coat can be black, wolf grey, fawn or yellow with white markings, or white with markings of these colors, with or without brindling.

Temperament

Temperament and personality

Calm, self-assured and protective, the Mâtin de l'Alentejo has a very strong sense of territory. He is affectionate and deeply attached to his family, while naturally remaining wary of strangers. His temperament makes him a very good guardian, vigilant without being needlessly aggressive.

Affectionate Intelligent Protective

Living together

Living with children and animals

On a daily basis, this dog appreciates a stable setting, space and clear reference points. He is not hyperactive, but he needs regular outings to let off steam and stay balanced. His gait is rather heavy and composed, and he often prefers to observe and control his environment rather than multiply demonstrations of excitement.

Training

Training and socialization

His training must be conducted with firmness, consistency and gentleness. Intelligent and courageous, he learns well when he is encouraged and rewarded, but his natural wariness and his independence require serious socialization from the earliest age. Brutality is counter-productive with this strong-willed breed.
