Three families arrive at the Animal Welfare League, each looking for a dog for a very special purpose. A couple with cerebral palsy longs to have a dog by their side and a loving labrador named Chai may be the perfect match. A family seeking comfort for their daughter with a heart condition meets an outgoing Jack Russell mix named Digger. And a mom looking for a best friend for her autistic son hopes a playful pug named Kirk is the right companion.
