In a recently published paper entitled "Burying Dogs in Ancient Cis-Baikal Siberia: Temporal Trends and Relationship with Human Diet and Subsistence Practices" Losey, Garvie-Lok, et al, study ritual burials of domesticated dogs in Siberia.
The paper provides the first in-depth analysis of the archaeological context, age, and diets of an array of ancient Cis-Baikal dogs in order to asses how the practice of dog burial relates to the chronology of human mortuary practices, dietary patterns, and subsistence strategies over the course of the last ~12,000 years.
