Prairie dogs live in highly complex social colonies and serve as keystone species; their persecution through poisoning and shooting has reduced their range by 98% and impoverished the grassland ecosystem.
Prairie dogs experience welfare harms at both individual and community levels. Mass poisoning kills entire colonies, causing rapid death but not without suffering. Survivors of colony destruction lose the complex social relationships and shared burrow systems central to their lives. Plague sweeping through a colony causes suffering across hundreds or thousands of individuals. They are highly social animals whose colony structure provides predator detection, communal raising of young, and complex communication — the loss of social bonds is a real welfare cost for individuals.
