Cindy Marabito runs a pit bull rescue out of her house in Austin, Texas. "We're the only raw-feeding, holistic, completely no-kill pit bull refuge and rescue in the United States," she says. She currently has nine dogs that roam her big, mulched backyard by the banks of the Colorado River.

The philosophy of her rescue is to give "low to no vaccines."
