About the Breed
The 3,000-year-old Xoloitzcuintli (pronounced "show-low-eats-QUEENT-lee"), the ancient Aztec dog of the gods, is today a loving companion and vigilant watchdog. The alert and loyal Xolo comes in three sizes, and in either hairless or coated varieties.
The Xoloitzcuintli  comes in three sizes (toy, miniature, and standard), and two varieties (hairless and coated). The hairless has tough, smooth, close-fitting skin. The coated variety is covered by a short, flat coat.     Both varieties come in dark colors, ranging from black, gray-black, slate, to red, liver, or bronze. The face is thoughtful and intelligent, and a Xolo's forehead will wrinkle when he's deep in thought. The Xolo's graceful, elegant body is surprisingly strong and rugged.
General Appearance: The Xolo is an ancient, natural breed, molded by evolution rather than selective breeding. A Xolo is moderate in all aspects of type and conformation, never extreme or overdone. Today the breed serves as a guard and companion. The Xolo possesses a clean, graceful outline, equally combining elegance and strength. There are two varieties, hairless and coated, identical except for coat and dentition. In the hairless variety, the principal characteristic is the total or almost total absence of hair. The coated variety is covered by a short, flat coat. In conformation, all three sizes are lean, sturdy, well muscled with a spacious ribcage, and moderate bone. The Xolo outline is rectangular, and the distance from the elbow to ground is equal to, or slightly greater than, the distance from the withers to the elbow. Typical Xolo temperament is calm, tranquil, aloof and attentive.
Size, Proportion, Substance: Height is measured at the highest point of the withers. Toy - Height at withers at least 10, and up to and including 14 inches. Miniature - Height at withers over 14 inches, and up to and including 18 inches. Standard - Height at withers over 18 inches, and up to and including 23 inches. Dogs less than 10 inches, or over 24 inches are disqualified. The body is slightly longer than height, in a 9/10 ratio measured from the point of the shoulder blade to the end of the rump. Medium, oval shaped bone is desirable. All three sizes exhibit moderately balanced proportions, and appear strong, sturdy, and well covered with smooth, flat muscle, but never coarse, heavy or over-muscled.
Head: Expression - Thoughtful and intelligent, vivacious, conveying the noble and faithful character of the breed, will show distinctive brow wrinkles when at attention. Eyes are almond shaped, medium size, neither sunken nor protruding. The color varies from yellow to black, the darker being preferred, but lighter color is acceptable. Both eyes must be of the same color. The eye rims may be less pigmented on light colored dogs. Light or spotted eye rims are tolerated but not preferred.
