Dogs really are man's best friend. New research indicates they can reduce stress, lower blood pressure, and even accelerate healing.

The Swedish Medical Center in Seattle, Wash., has developed a program known as Therapy Pups.

Dogs like Armani visit the surgery floors on a regular basis.

They're also outfitted with cameras. A custom made harness is wrapped around the dog's head.

The pup cams are getting thousands of views online and the pups themselves are a hit with the patients.

The hospital started therapy pups in 2008 and they plan to expand the program.
