Grizzler the 'pho-dog-rapher'

A dog named Grizzler became a pioneer "pho-dog-rapher" when Nikon strapped a camera in a special case to his chest. The camera is triggered when his heart rate rises.

Grizzler's photos include images of other dogs, people's feet and cats that aren't happy to see him.

Van full of food

Grizzler's interests are varied, ranging from other dogs to cats to anything that is potentially edible. This van full of oil and canned beans ramped up his excitement level, triggering his chest-worn Nikon camera to take a photo.
