The PIO comes in the coated and the hairless varieties. The hairless though are more preferred. Peruvian Hairless dogs come in three sizes:
the small which stands 10 to 16 inches, the medium which are 16 to 20 inches and the grande or the large that are known to measure from 20 to 26 inches tall. Skin
colors would range from elephant gray, copper and chocolate brown. Some dogs are mottled, others have one distinct color and a number of dogs would have pink spots.
Eye color would depend on the color of the skin. Hairless PIOs have wrinkled lips. The candle flame shaped erect leathery ears are at times covered with wisps of hair.
Some dogs would also grow crew cut hair on top of the head. Skin is pliable and soft. The hairless variety lack premolars and most of these dogs would become toothless
Coated PIO’s hair is at times the same as a Doberman’s in length. Some powder puff PIOs would have longish hair similar to that of a Collie’s. The
most common color is white with variedly colored and shaped patches. This hairy version of the PIO breed has rose ears. Because of the dense hair covering, the ears are not
pricked. The coated variety has full dentition.
Both the hairless and the coated Peruvian Inca Orchids are lithe with light boned and well muscled bodies. Both
have long tapered tails.
Head: Lupoid in structure. Broad skull. Stop not very
pronounced. Straight nosebridge. Tight-lipped. Dentition almost
always incomplete (missing one or all premolars and molars). Nose
matches coat color.
Ears: Medium in length, nearly
pointed at the tips. Erect in action. Lying back against the head at
Eyes: Medium-sized, slightly almond-shaped.
Ranging from black to brown to yellow, depending on coat color.
Body: Medium-sized. Domed topline. Withers not very pronounced.
Chest of good width. Ribs slightly well-sprung. Straight back.
Rounded, solid croup.
Tail: Set on low. Fairly thick at
the base, tapering toward the tip. In action, raised in a curve
above the topline but not curled. At rest, hanging down with a
slight upward hook at the tip.
Hair: Vestiges of hair
allowed on the head, lower legs, and tip of the tail. Sparse hair on
the back also allowed.
Coat: Hair is black in the black
variety. In other varieties, hair is slate black, elephant grey,
bluish-grey, any other shade of grey, or dark brown to light blond.
All colors solid or with pinkish spots anywhere on the body.

Weight: Large: 12 to 23 kg. Medium: 8 to 12 kg.

The origins of this very ancient breed are hotly debated. The
Peruvian Hairless Dog may have been brought to Peru by Chinese
immigrants or by groups migrating from Asia to the Americas via the
Bering Strait. Others believe he comes from Africa. Nevertheless,
there is irrefutable evidence, including representations of the dog
on pottery, that the breed has inhabited Peru for many centuries and
existed even before the Incas. The Peruvian Hairless Dog was once
the favorite pet of Incan royalty. He is now rare in his native
country. The breed comes in three sizes with fairly similar body
Lively, alert, and fast, this calm, intelligent, affectionate dog is
a good pet. He is distrusting of strangers and therefore makes a
The genes that cause hairlessness also result in the breed often having fewer teeth than other breeds, mostly lacking molars
and premolars. Some are born with more dentition than others.
One theory is that the hairlessness trait is recessive-lethal, which means
that homozygotic hairlessness doesn't exist. This results in an average birthrate of 2:1, hairless : coated.
While they are recognized by
the American Kennel Club (AKC) for its Foundation Stock Service as Peruvian Orchid dogs, they cannot be shown at AKC shows, they are also registerable
with FCI, UKC, NKC,APRI, ACR. Some breeders think that interbreeding with coated (Peruvian) dogs is required to maintain functional teeth and nervous system
health in subsequent generations. They say that breeding of hairless with hairless (and common but unacknowledged culling of hairy pups from litters to maintain
a "pure" image) leads to short-lived dogs with serious health problems. However, other breeders (especially in Peru) think the opposite, and are doing well (for
centuries already), too.
Like all breeds there are some health problems. These include IBD, seizures, stroke, and skin lesions. They are very sensitive
to toxins and care should be taken in use of insecticides. Insecticides are absorbed through the skin, and body fat keeps these toxins from entering the liver
too quickly. Since these dogs have very low body fat, toxins are absorbed too quickly and cause severe damage to the nervous system and GI tract.
An indoor dog, he cannot tolerate bright sunlight and cold
temperatures. His skin must be rubbed with a moisturizer.
