From the WSJ:
Walk into psychiatrist Drew Ramsey's office in Manhattan and you'll likely be greeted by Gus, a four-year-old shih tzu.
Some patients pat Gus while they talk to Dr. Ramsey. A few talk to Gus instead. And if they get emotional, Gus provides physical comfort that therapists can't offer. "We can't hug patients, but patients can hug Gus," says Dr. Ramsey, who began bringing his dog to his office two years ago.
