Playing fetch - GoPro human chest mount on dog

My Australian Shepherd, Legend, playing fetch while wearing a GoPro camera. It is mounted using the chest mount for people. We don't own the mount for dogs yet. Nonetheless, he had fun. :)
The chest mount was tightened to be small enough for his frame. I had the camera hang to his side because it didn't look like it would be comfortable if the plastic mount balanced on his back/shoulder blades. It was still an okay angle and the biggest issue was the camera knocking on the objects next to Legend.
