We usually take picture of things we’re excited about, but what if a dog could do the same thing? Nikon recently created their ‘Heartography’ project to see what gets dogs excited, using a happy dog named Grizzler as the product tester for their special camera mount with a built-in heart-rate monitor. Whenever he saw something that made his heart beat rise, he snapped a picture. Is anyone really surprised by what Grizzler took pictures of?
