Special pet, special care. Diet, provenance, and health analyses of a dog reveal strong ties with humans in Patagonia

The introduction of the dog in Patagonia is recorded from the Late Holocene. Documents from the nineteenth century indicate that dogs had various utilitarian roles among hunter-gatherers, including hunting aids, protection and war, carrying loads, and as exchange goods. Most of them had no special status, typically subsisting on food scraps and hunting leftovers, were in bad or poor physical and nutritional condition, and suffered physical abuse. Nevertheless, a select few dogs, including those of the hairless variety, received special care and attention from humans. They were in good physical and nutritional condition and appeared to have been used as companion animals of people with prestigious positions. These dogs were regularly provided with cooked food, owned horses, and even were offered sacrificed horses as a form of treatment during their illnesses. Through an interdisciplinary osteobiographical study (phenotype, age, stable isotopes –δ¹³C, δ¹⁵N, δ¹⁸O–, microremains of the dental calculus, paleopathology, and entheseal changes), we evaluate whether a dog recovered from a funerary context of Patagonian hunter-gatherers represents the archaeological correlate of a special position animal. The canid exhibited mobility impairments that surely prevented it from hunting large herbivores. Despite this, it was regularly fed meat from human prey and human-made meals containing fruits of Neltuma sp. and underground storage organs. Following its death, the dog was given an individual burial within a mortuary niche located in a dedicated area for human bodies. The results provide evidence that this canid held a special or distinct position, possibly indicating emotional bonds with the hunter-gatherers.
