The Xoloitzcuintle (Mexican Hairless) Standard is the largest variation of the ancient Xoloitzcuintle breed, known for its unique appearance, intelligence, and loyalty. Originating in Mexico over 3,000 years ago, this breed was highly valued by the Aztecs, Toltecs, and Maya for its spiritual significance, companionship, and supposed healing properties. The Standard Xoloitzcuintle has maintained its status as a symbol of Mexican heritage and a beloved companion for many. The Standard Xoloitzcuintle typically stands between 18 to 23 inches tall at the shoulder and weighs between 30 to 55 pounds. They have a lean, muscular build that highlights their natural agility and athleticism. Their skin is smooth and tough, and can come in a range of colors including black, gray, slate, red, bronze, and liver. Some individuals may have small patches of hair on their head, feet, or tail. Their large, upright ears and almond-shaped eyes give them an alert and intelligent expression. The Standard Xoloitzcuintle is known for being intelligent, loyal, and calm. They form strong bonds with their families and are affectionate and protective, making them excellent companions. Though reserved with strangers, they are not aggressive and typically warm up once they feel comfortable. Their natural alertness and protective instincts make them effective watchdogs. Early socialization and consistent training are essential to help them develop confidence and adapt well to different environments. They are intelligent and respond well to positive reinforcement, making training both effective and rewarding. The Standard Xoloitzcuintle has moderate energy levels and requires regular exercise to stay healthy and content. Daily walks, play sessions, and mentally stimulating activities, such as training and puzzle toys, are important for keeping them engaged. They enjoy spending time with their owners and are happiest when they can participate in family activities, whether indoors or outdoors. Grooming a hairless Standard Xoloitzcuintle involves specific care to maintain healthy skin. Regular bathing with a gentle, non-irritating shampoo helps keep their skin clean, and moisturizing may be necessary to prevent dryness. Sunscreen is recommended when they spend extended time outdoors to protect their skin from the sun. Routine ear cleaning, dental care, and nail trimming are also important for overall health. If they have small patches of hair, occasional brushing can keep those areas tidy. Standard Xoloitzcuintles have a lifespan of around 12 to 15 years and are generally healthy. However, like other breeds, they can be prone to certain health issues, such as skin conditions and dental problems. Regular veterinary checkups, a balanced diet, and responsible breeding practices contribute to their long-term well-being.
