475 remaining beagles from Ridglan Farms will be transferred to Big Dog Ranch Rescue and partner groups, completing the shutdown of the Wisconsin breeding and research facility.
1,500 dogs had already been bought from the site after spring protests, and the latest agreement means, as the rescue group put it, "not one dog will remain."
1,000 activists clashed with police during an April rescue attempt that led to 29 arrests, intensifying pressure after years of criticism from Peta and other animal-rights groups.
October's settlement over criminal animal-abuse allegations forced Ridglan to surrender its breeding and sales license, and the rescued dogs are now headed to Florida and Alabama for sterilization and adoption.
