Camera takes a photo every time dog gets excited and the results are hilarious

A series of photographs has given an insight into the variety of things which get dogs’ hearts racing through an innovative camera system. The pictures were taken by a sheepdog called Grizzler.

As any dog owner will tell you, it doesn’t take much to send our four-legged companions into a frenzy of excitement. From the postman’s arrival to their human’s return from the office, or simply hearing the magic word “walk”, they display boundless enthusiasm for virtually everything.

A collection of snapshots has offered a fascinating glimpse into the range of things that set dogs’ pulses racing, thanks to a groundbreaking camera innovation. The images, shared on Instagram, were captured using technology created by camera manufacturer Nikon, which works by fixing a camera to a dog and snapping a picture whenever their heart rate spikes.

The photographs were shot by a sheepdog named Grizzler, with thishowthingswork posting them on Instagram alongside the caption: “This dog wore a camera that snaps photos whenever its heart rate jumped due to excitement, and the results are fantastic!”

According to the post’s description: “The system was developed by Nikon and is called Heartography, a new technology that combines a heart rate monitor with a camera. When the monitor detects a surge of excitement or even fear, it automatically triggers the shutter, freezing that exact moment in time without any human input.

“The idea works perfectly for a dog like Grizzler, who gets excited about nearly everything around him. Walks, people, smells, and surprises all send his heart rate soaring.

“During early tests, Grizzler wore the camera throughout his day, unknowingly capturing moments only a dog could notice.”

The images reveal other cheerful dogs approaching to greet Grizzler, as well as his feeding dish – along with some more unexpected sights, including a tank full of crabs, and a turtle paddling near the banks of a stream, lake, or river, reports the Mirror.

Several more shots capture something that gets any dog worked up – cats peeking out from amongst plant pots, through a window, and beneath a pile of chairs.

Grizzler also seemed thrilled to spot a pigeon making its way towards what appears to be a mound of crumbs on a crisp packet, plus a car boot crammed with boxes labelled ‘Mazola corn oil’ and tins of Heinz baked beans.

Photography site PetaPixel provided further details about how the Heartography device operates. “The mount system features two sides: the heart rate collar and the special camera case,” it explained.

“The collar is worn around the dog’s neck, monitors its heart rate, and constantly sends the number to the camera case wirelessly. The camera case displays the current heart rate on an OLED screen.

“Buttons next to the display let you choose the baseline heart rate that triggers photos. Whenever the dog photographer’s heart rate goes above the threshold – indicating a spike in emotions and/or activity – the case will snap a photo with the Nikon compact camera contained within.”

Instagram followers were blown away by the snaps. One commented: “Love how he got happy an excited seeing all his pals!!” Another person commented: “Food and animals. I can relate.”

Another quipped: “Corn oil and baked beans will increase anything’s heart rate.”
