Coprophgia: Why does my dog eat poo?Lindsay proposes that as a consequence of changes in fortune over the period of domestication, dogs would have experienced hard times requiring them to survive on human garbage and faeces.This he claims may have “…been encoded over time as a genetic trait. Dogs that could subsist on such a diet would have had a distinct survival and reproductive advantage over dogs that refused to eat such things”. Subsequently, dogs that fed on refuse acquired a tolerance to the illnesses that could be caused by the ingestion of unhealthy food and faeces.
