List of domestic dogs

The Peruvian Hairless Dog ( Spanish Perro sin pelo del Perú ) is a breed of dogs from Peru recognized by the FCI ( FCI Group 5, Section 6, Standard No. 310 ). In Peru, the dog breed is also known under the name Viringo .

Origin and history

The origin of the Peruvian hairless dog is still largely unclear. According to images on archaeological finds and old dog skeleton finds, it is assumed that the breed has existed in South America for over 1000 years. The dogs, now a national cultural asset in Peru, were already considered to be special pets at that time and were revered and valued for their healing properties against diseases. They are closely related to the Mexican hairless dogs and the Chinese Crested Dogs .


The Peruvian Hairless Dog is a slender, elegant dog with a greyhound-like appearance. The FCI divides this breed into three size classes, each with an adapted weight:

  • Small: from 25 to 40 cm, up to 8 kg,
  • Medium: from 40 to 50 cm, up to 12 kg,
  • Large: from 50 to 65 cm, up to 25 kg.

The furlessness of the breed resulted from a spontaneous mutation , which in the course of evolution did not give the naked dogs any disadvantages or possibly even advantages (e.g. lower susceptibility to parasites ) compared to their hairy relatives. Due to the early use as domestic animals, there could also have been a human advantage beyond natural selection.

The breed standard permits the presence of some hair residue on the head and at the ends of the limbs and tail , with the breeding aiming for complete hairlessness. The color of the smooth, thick and elastic skin ranges from black to gray in different tones through dark brown to light blonde. All of these colors can be monochrome or spotted with white. While the dark breed representatives just get "brown" in summer, the light-skinned and spotted ones have to slowly get used to the sun's rays and, if necessary, protect them with sunscreen.

The medium-sized ears must stand upright in the attentive dog, when they are at rest they are often placed backwards.

The mutated allele that causes furlessness (H) is dominant for this trait , but leads only heterozygous ( genotype Hh) to viable offspring. The embryos that are homozygous (HH) for lack of fur do not develop any further shortly after conception and are resorbed in the womb ( recessive lethal factor ). Because naked dogs only exist with heterozygous genotypes, they cannot be bred purely: During breeding, hairy Peruvian naked dogs (genotype hh) are also produced, which, like the South American mountain goelots, are called "peludos". The mutated allele also appears to be linked to the predispositions for tooth development. Naked dogs almost always have incomplete dentures.


Peruvian hairless dogs are one of the archetypal dog breeds and have therefore retained some of the original behaviors. The dogs are attentive, intelligent, self-confident, independent and agreeable. They bond closely to their owners. They are often reluctant to react to strangers, but not fearful or aggressive. Typically sighthounds, Peruvian hairless dogs are very calm and adaptable in the house, but also vigilant.
