A great chew for all sizes! These dehydrated chews come from 100% pasture-raised pork. Hormone-free and certified humane. No antibiotics, No chemicals, No pesticides. Sourcing: White Oak Pastures in Bluffton, Georgia and Joyce Farms in Winston Salem, North Carolina. ***We choose to source from working farms which means animals may not mature on our timetable. At times, this means we will not have access to unlimited inventory.
