Dog Harness for SJCAM Sport Cameras SJ4000 SJ5000 SJ6000 and Xiaomi Yi Action Camera and GoPro Hero 4 Hero 3+ Hero 3 Camera: Dog Harness(Fetch, Dog Strap) + J-Hook + Quick Release Buckle

I've only used this harness a couple of times but it works pretty good. At first I was concerned about the snug fit under my dog's forelegs but he didn't seem to mind and it was necessary to keep the camera in place. The only downside comes when my dog takes off on a run. The camera gets bounced all over the place and the footage is essentially useless. It would be nice if there was some sort of stabilization I could add but I'm not sure even that would work when my dog is running. This is an unfortunate thing but by no means a dealbreaker.On the bright side, when he is just walking, I get some really cool footage. I am going to buy a second camera soon so I can use the upper and low mounts at the same time. Getting to see things from the dogs perspective is interesting and the creative possibilities are endless.Construction and materials seem pretty rugged. Its easy to put on and take off my dog and he doesn't show any discomfort or irritation even after a long game of fetch. My dog is German Shepherd size and the harness and camera work well due to his size. I'm not sure how well it would work on a smaller dog.
