Prairie dogs are keystone species of North American grasslands whose persecution through poisoning and shooting has cascading welfare consequences for dozens of dependent species.
Prairie dog persecution has caused enormous suffering both to prairie dogs themselves and to the dependent species whose welfare is tied to prairie dog towns. Poisoning using zinc phosphide causes painful deaths. Colony destruction eliminates shelter, food, and social bonds for hundreds of individuals simultaneously. The black-footed ferret came within a few individuals of extinction due to prairie dog decline. Restoring prairie dog populations is simultaneously a welfare intervention and a conservation priority. Social burrowing animals like prairie dogs have complex emotional lives including alarm calls, play, and apparent grief at death of conspecifics.
