1. Xoloitzcuintli

The Xoloitzcuintli, often called the Mexican Hairless Dog, is among the rarest ancient breeds. With a history spanning over 3000 years back to Aztec times, this breed emerged naturally, not through human experiments. The Aztecs revered them as guides for souls in the afterlife. Xoloitzcuintlis come in hairless or coated varieties and in toy, miniature, and standard sizes. Their bare skin demands regular care to avoid sunburn and irritation. These dogs are smart and devoted companions, known for their serene demeanor, keen awareness, and deep loyalty. Their warmer body temperature makes them fantastic therapy dogs, especially for those seeking comfort. Their bold look and storied past make them utterly fascinating.
