What are the three distinct size classifications recognized within the Xoloitzcuintli breed standard?
Answer
Standard, Miniature, and Toy
The breed standard for the Xoloitzcuintli formally recognizes three distinct size categories. These are the Standard, Miniature, and Toy classes. While specific measurements regarding height and weight are used to officially differentiate between these three groups, the fundamental structural proportions and the characteristic head shape are maintained across all size variations. This dimensional flexibility is noted as unusual for many ancient breeds, which often stabilized into a single utilitarian size over millennia of development.
