The Estrela Mountain Dog is a large, powerful athletic dog, strongly muscled with substantial bone. The body is short backed and the head is in proportion to the size of the dog. The Estrela comes in two coat varieties and coat colors include shades of fawn, wolf gray, yellow, with or without brindling, with or without white markings, or with shadings of black throughout the coat, and with or without a dark facial mask. Estrelas have uncropped, small, triangular rose ears. The thick tail hangs down when at rest and should have a natural “hook” resembling a scimitar. The Estrela Mountain Dog should be evaluated as a working livestock guardian capable of protecting stock in mountainous terrain, and exaggerations or faults should be penalized in proportion to how much they interfere with the dog’s ability to work.

The Estrela Mountain Dog is a faithful watchdog of the herds he protects and a formidable opponent for any predator. This breed is intelligent but independent; loyal and affectionate to owners but indifferent to others; calm but fearless and quick to react to danger. The Estrela Mountain Dog is a wonderful guardian of property and home, and can also be trained as a draft dog.

The Estrela head is long and powerful in appearance but proportionate to the size of the dog. Viewed from the side, the skull and muzzle are of equal length, and joined by a moderate stop. The skin on the skull and cheeks is tight.
Faults: Head too long, narrow or pointed.

SKULL – The skull is slightly domed and broad between the ears, tapering gradually toward the muzzle. The supraorbital ridges are only slightly developed and the occiput may be evident. Cheek muscles are well developed but the cheekbones are flat.
Faults: Skull too flat or narrow.

MUZZLE – Long, tapering towards the tip, but not pointed. Almost straight, but very slightly convex at the tip (aquiline nose). Lips are large and tight, not thick or pendant, and without flews. Mucous membranes of mouth and palate and rims of the lips are preferably intensely black pigmented.
Faults: Snipey or pointed muzzle, over-developed flews and incomplete or absence of pigmentation.

TEETH – The Estrela Mountain Dog has a complete set of evenly spaced, white teeth meeting in a scissors bite.
Faults: Undershot or overshot bite.

NOSE – Nostrils straight, wide and well open. Always darker than the coat, preferably black.
Faults: incomplete or absence of pigmentation.

EYES – Eyes are oval, medium size and set level, preferably dark amber in color. Eyerims are tight and preferably black. Eyebrows slightly marked. Expression is keen and calm.
Faults: Yellow eyes, wall eyes, eyes different in size.

EARS – Ears are rose, moderately high set, and small for the size of the dog (about 4 3/8” length and 4 7/8” width), thin, triangular, rounded at the tip; and carried falling backwards against the side of the head, with a small portion of the inner edge showing.
Faults: Incorrect set on; drop ears; ears too big, too fleshy or too round.

Straight, short and thick; well set into shoulders; with a modest tuft of hair under the throat.

The shoulder blades are long and wide and laid back at an angle of about 65 degrees from the horizontal. The upper arm is muscular and lays at an angle of about 55 degrees from the horizontal. The elbows are close to the body. The forelegs are straight and vertical, with round, sturdy bone and strong, broad, slightly sloping pasterns. The length of the foreleg is about equal to the distance from the withers to the elbow.

A properly proportioned Estrela Mountain Dog is preferably square in outline, but slightly longer than tall will be accepted. Whether the dog is standing or moving, the line of the back is short, strong and nearly level from the withers to the slightly sloping croup. The loin is moderately short, wide, muscular, and deep, with only a slight tuck-up. The ribs extend well back and are well sprung out from the spine, forming a broad, strong back, then curving down and inward to form a deep body. The brisket extends to the elbow. Viewed from the front, the chest between the forelegs is broad and muscular.

The hindquarters are muscular and wide. The rear angulation is in balance with the front angulation. When the dog is standing, the broad rear pasterns are slightly let down, perpendicular to the ground and, viewed from the rear, parallel to one another.

Feet are in proportion to the size of the dog, oval in shape with thick, well-closed toes. Pads are thick and hard with abundant hair between them. Nails are dark, preferably black. Rear legs may have single or double dewclaws, Dewclaws may be removed.

The scimitar-shaped tail is an essential element of Estrela breed type. It is set moderately low. It is thick and muscular at the base and tapers to the tip. A tail of the correct length extends at least to the hock. When the dog is relaxed, the tail hangs down naturally. When the dog is moving or alert, the tail can raise above the horizontal curving upwards, forwards, sideways or even downwards. The tail is well furnished with hair and in the long-haired variety, the tail is well feathered. Faults: Docked, rudimentary, congenitally absent.

The Estrela Mountain Dog comes in two coat types. Both types should have coat resembling the texture of goat hair.

Long coat: The thick, slightly coarse outer coat lies close over the body and may be flat or slightly waved, but never curly. Undercoat is very dense and normally lighter in color than the outer coat. The hair on the front sides of the legs and the head is short and smooth. Hair on the ears diminishes in length from the base of the ears to the tips. The hair on the neck, the buttocks, the tail, and the back side of the legs is longer resulting in a ruff at the neck, breeches on the buttocks and backs of the legs, and feathering on the tail.

Short coat: The outer coat is short, thick, and slightly coarse, with a shorter dense undercoat. Any feathering should be in proportion.

Fault (both coat types): Coat texture too harsh or too soft.

Fawn, wolf gray and yellow, with or without brindling, white markings, shadings of black throughout the coat, and preferably with a dark facial mask. Disqualification: Albinism.

Desirable height for mature males is 25½ - 28½ inches and for mature females is 24½ - 27 inches. Mature males in good working condition weigh between 88 and 110 pounds. Mature females in good working condition weigh between 66 and 88 pounds. Faults: More than 1½ inches in height above or below approved range.

Movement is free and easy. Dogs should not be penalized for carrying the head level with the topline in motion.

Unilateral or bilateral cryptorchid. Extreme viciousness or shyness. Albinism.
