A remarkable new study from the University of Calgary has revealed that the ancient Maya were not just trading jade, cacao, and obsidian across vast distances. They were also trading live dogs, selectively bred, specially fed, and transported hundreds of kilometres as valued commodities and possibly even as royal gifts.
Dr. Elizabeth Paris and her international team studied the bones and tooth enamel of dogs and deer excavated from two Maya highland sites in Chiapas, Mexico: Moxviquil and Tenam Puente. Using strontium isotope analysis, a technique that reads the chemical signature of the soil and water an animal consumed while its teeth were forming, the researchers were able to identify precisely where each animal had spent its early life. The deer tested as locally sourced wild animals, but the dogs were a different story entirely. Their strontium signatures pointed unmistakably to distant lowland Maya kingdoms on the Yucatan Peninsula, hundreds of kilometres away from where their bones were found.
Even more striking was the diet these dogs received. Stable carbon and nitrogen isotope testing revealed that the traded dogs were fed an unusually rich diet heavy in corn and meat, essentially the same food their human owners were eating. This deliberate, specialised feeding strongly suggests these were not strays or working animals but prized possessions raised with care and intention. The dogs may have belonged to the mysterious Xoloitzcuintli breed, a hairless dog sacred to Mesoamerican cultures, a theory supported by unusual tooth shapes in the specimens that are characteristic of this breed's genetic mutations.
Maya artwork from the lowland kingdoms depicts rulers reclining in hammocks with small dogs resting beneath them, suggesting these animals were symbols of status, alliance, and royal identity. The distances involved in trading them alive speak to the extraordinary reach and sophistication of ancient Maya commercial and diplomatic networks. 🌿
