20 Rare Dog Breeds You Probably Never Knew Existed

1. Xoloitzcuintli

The Xoloitzcuintli, or Mexican Hairless, is among the oldest and rarest breeds, tracing over 3,000 years to Aztec times. It arose naturally, not by modern tinkering. Ancient people believed it guided spirits to the afterlife. It may be hairless or coated, and appears in toy, miniature, and standard sizes. Bare skin needs steady care to avoid burn and irritation. Xolos are bright, loyal, calm, and watchful. Their warm bodies soothe people in need of heat. Their bold outline and deep heritage make them singular.
