Nikon has hooked up a heart rate sensor and camera to Grizzler the dog to capture the moments of the day that excite him.

Using a photography method called Heartography, Grizzler the Border Collie would capture an image from a chest mounted camera every time he gets excited or happy, granting viewers an insight into the dog’s daily ups and downs.

On Heartography, a Nikon statement read: “Photos can capture the world's beauty within a single frame, and photographers translate what they feel into what others can see.

"With a device that reacts to increased heart rates, we can literally connect emotions to every photo.”

Grizzle's raised heart rate would set off the chest mounted camera via a Bluetooth connection. Nikon admitted that "due to Grizzler's high energy and active movements, several shots were blurred, so we only picked the best shots to be featured in this video".
