The Xoloitzcuintli, also known as the Mexican Hairless, is one of the oldest and rarest dog breeds, dating back over 3,000 years. It originates from Mexico and comes in three sizes: toy, miniature, and standard. The Xoloitzcuintli is known for its distinctive hairless coat, though there is also a coated variety. The hairless version has smooth, exposed skin and is often seen with a unique, smooth texture and a warm, soft feel. This breed can also have a sparse coat of hair in some areas, especially on the head, feet, and tail. The breed is known for its calm, affectionate, and loyal nature. Xoloitzcuintlis are intelligent and adaptable, making them good companions for various living situations. They are generally good with children and other pets and can be reserved with strangers. Due to their hairless nature, they require regular skin care to protect against sunburn and skin irritations. The Xoloitzcuintli has a low-maintenance coat compared to other breeds, and the coated variety requires minimal grooming. Overall, this breed is a unique and devoted companion with a rich history and a gentle demeanor.
