An unusual breed where the breed standard lists the most important characteristic as having no hair; though some short hair on the top of the head, feet and tip of tail is allowed.
Some time ago the breed was in decline and risked becoming extinct. Recognising the importance of the breed to the cpuntry, the Peruvian Government afforded the breed special protections. What these protections mean in practice is uncertain except that many lowland archaeological sites seem to have one of the dogs wandering around (which is surprising given their character is generally affectionate with family but wary of strangers (from Wikipedia, Peruvian Hairless Dog)).
Interestingly, the gene that makes the dogs hairless also causes them to have fewer teeth (puppies have a full set but adults don’t, mainly missing molars and premolars). Additionally, the hairless gene is double dominant lethal i.e. two copies of the hairless gene (one from father, one from mother) is fatal and embryos do not develop in the womb. This means that around 33% of puppies are born “coated”.
Unfortunately, the breed does have various health issues including IBD, seizures, stroke, and skin lesions as well as being particularly sensitive to toxins.
