From sled teams working on snowy flats to puppies disrupting yoga classes and truffle hunters digging through Italian forests, dogs help humans every day with jobs large and small.

Traveling the world, John Fabiano snaps pictures of these canine professionals, who he introduces readers to in his debut photo book. In Working Dogs, meet pooches working on boats, in therapy sessions, on the sheep farm, rescuing people in avalanches and beyond, and learn about all the incredible work man's best friends are capable of with their own four paws.
