Group 7 (Non Sporting)
According to certain experts, this dog was introduced in Peru during the Chinese immigration, soon after the promulgation of the law abolishing the slavery of blacks by the President of Peru, Don Ramon Castilla. On the other hand, other searchers suppose that this dog comes from the African continent through the intermediary of nomads who arrived in America accompanied by their hairless dogs. Another possible explanation is that the presence of this dog would be due to the migration of men and their dogs from Asia to America through the Bering Strait. However, next to all these suppositions, there are certain proofs such as the representations which appear on ceramics of different pre-Inca civilisations (Vicus, Mochica, Chancay, Chancay under Tiahuanacoid influence, Chimu); in many cases the hairless dog has replaced the Puma, the snake or the falcon, this in particular and in a more evident way in the Chancay culture. As we can gather from the reproductions, the hairless dog appears during the pre-Inca archaeological periods, i.e. between the years 300BC and the years 1400 AC.
Going by his general conformation, it is an elegant and slim dog, whose aspect expresses speed, strength and harmony without ever appearing coarse. There are two varieties, the hairless whose main feature is the absence of hair all over the body and the coated variety, that is entirely coated. Another particular feature is that the dentition in the hairless variety is nearly always incomplete associated with the congenital alopecia.
IMPORTANT PROPORTIONS: The ratio between the height at the withers and the length of the body is 1 : 1; the females can be slightly longer than the males.
This breed has, as a fundamental characteristic, the absence of hair all over the body. Another particular feature is that the dentition is nearly always incomplete. Noble and affectionate at home with those close to him, at the same time lively and alert; he is wary and a good guard in the presence of strangers.

Head And Skull:
The head is of lupoid [wolf] like conformation
Skull: Mesocephalic. Orthoid, i.e. the upper axes of the skull and muzzle are parallel; a slight divergence is accepted. Seen from above, the skull is broad and the head tapers toward the nose. The superciliary arches are moderately developed. The occipital protuberance is barely marked.
Stop: Slightly marked (approximately 140°).
Nose: Good pigmentation, the colour of the nose must be in harmony with the different colours of the skin; in the different shades in the hairless variety and with the colour of the hair in the coated variety.
Muzzle: Seen in profile, the nasal bridge is straight.
Lips: They must be as tight as possible and close to the gums.
Cheeks: Developed without exaggeration.
Alert and intelligent expression. The eyes must be of average dimensions, slightly almond shaped, neither deep-set nor prominent, normally and regularly placed, i.e. neither too close together nor too wide apart. The colour can vary from black, going through all shades of brown to yellow, in harmony with the skin colour in the naked variety and with the coat in the variety with hair. In any case, both eyes must be of the same colour. The colour of the eyelids may go from black to pink in subjects with light coloured face. The light pink colours are admitted but not sought after.
The ears must be pricked when the dog is attentive, whereas at rest, they are laid towards the back. The ears are of medium length; broad at the base, tapering progressively towards the tip, ending almost pointed. The ear set starts on the upper part of the skull to end laterally and obliquely. In erect position, the axes of the ears form a variable angle from 50° to near 90°.
Jaws/Teeth: The incisors should fit in scissor bite. In the hairless variety the absence of one or more teeth is accepted. In the coated variety the dentition must be complete with teeth normally developed and in a normal position. The jaw is not strongly developed.
The upper line is curved (convex). The length is approximately the same length as the head. The shape is near to a truncated cone shape, supple, with good musculature. The skin on the neck is fine, smooth and elastic. Really close to the subcutaneous tissues. No dewlap.
Well united with the body. Seen from the front, they are perfectly vertical and the elbows are not turned out. The angle at the shoulders joint varies from between 100 degrees and 120 degrees. Seen in profile, the angle formed by the pastern and the vertical will form 15 degrees to 20 degrees.
Topline: Level, although certain subjects show a dorsal-lumbar convexity, which disappears at croup, level.
Withers: Barely accentuated. Back: Straight, with well-developed back muscles often forming all along the back a muscular bi-convexity, which extends to the lumbar region.
Loin: Strong and well-muscled. Its length reaches approximately 1/5 of the height at the withers.
Croup: The superior profile is slightly convex, slanting approximately 40° to the horizontal. Solid and well-muscled giving a good push.
Chest: Seen from the front, the chest must have good amplitude, but without excess; reaching almost to the elbow. The ribs must be slightly sprung, never flat. The chest, measured behind the elbows, must exceed the height at the withers with approximately 18%.
Underline and belly: The lower profile presents an elegant and well-marked line which goes from the lower part of the chest and rising to the belly which must be well tucked up, but without excess.
The muscles are rounded and elastic. The curve of the buttocks is well marked. The coxal-femoral angle varies between 120° and 130°. The femoral-tibial angle must be of 140°. Seen from behind the hindquarters must be upright.
Forefeet: Are semi-long and look like hare-feet. The pads are strong and heat-resistant. The inter-digital membranes are well developed. The black dogs have preferably black nails and the lighter coloured dogs light nails.
Hind feet: Same as forefeet.
The tail is set on low. Of good thickness at its root, it tapers towards its tip. When excited, the dog can carry the tail raised in a round curve above the backline, but never as curved as being rolled up. At rest, it hangs with a slight upward hook at the tip. Sometimes carried tucked in towards the abdomen. In length it almost reaches the hock. The tail must not be docked.
Due to the angulations defined at the description of the limbs, some of these dogs move with shorter steps but faster and at the same time quite soft and flexible. The limbs, seen from front or behind must move in a single line (i.e. single tracking).
Hairless variety: Without hair, only very few hairs on the head and at the extremities of the legs and the tail are admitted, and sometimes sparse hair on the back. These hairs can be any colour or combination of colours.
Coated variety: Smooth, short and tight coat. The hair can be any colour or combination of colours.
SKIN: The skin must be smooth and elastic all over the body, but can form a few rounded almost concentric lines on the head and round the eyes and the cheeks in the hairless variety. It has been verified that the internal and external temperature of the hairless dogs is exactly the same as that of other breeds (coated or not). The absence of hair leads to an immediate and direct emanation of heat, different from the coated subjects, where the heat filters through the coat by natural ventilation.
The colour of the skin in the hairless variety can vary from black, slate black, elephant black, bluish black, the whole scale of greys (diluted black), all nuances of genetic blue, dark brown going to light blond. All colours can be either uniform or show pinkish or white patches on all parts of the body. White or pink spots must not cover more than 1/3 of the body. Solid colours are preferred.
There are three sizes in the males and females -
Small from 25 to 40 cm (9 ¾ to 15 ¾ inches)
Medium from 40 to 50 cm (15 ¾ to 19 ¾ inches)
Large from 50 to 65 cm (19 ¾ to 25 ¾ inches)
The weight is in the size of the males and females -
Small from 4 to 8 kg (8.8 to 17.6 lbs)
Medium from 8 to 12 kg (17.6 to 26.4 lbs)
Large from 12 to 25 kg (26.4 to 55.1 lbs)
Any departure from the foregoing points should be considered a fault and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog.
• Semi-erect ears, one or both. • Pincer bite. • Absence of PM1 in the coated variety. • White or pink spots covering more than 1/3 of the body in the hairless variety. • Presence of dewclaws.
• Aggressive or overly shy dogs. • Any dog clearly showing physical or behavioural abnormalities shall be disqualified. • Over or undershot bite. • Deviated jaw (i.e. wry mouth). • More than one teeth missing in the coated variety. • Hanging or cropped ears. • Tongue normally hanging outside of the mouth (paralyzed). • Eyes of different colour (heterochromatic). • Tail-less, short tail or docked tail. • Presence of hair in the hairless variety on parts of the body not indicated in the standard. • Total or partial de-pigmented nose. • Height more than 65 cms and less than 25 cms. • Albinism.
Male animals should have two apparently normal testicles fully descended into the scrotum.
Only functionally and clinically healthy dogs, with breed typical conformation, should be used for breeding
