I've got one that I used to use. I have a human chest mount that I kind of modified to sit on top of the dogs back. Also used the human head mount and put it through the dog collar so it sat just under the dogs mouth, near the front of their chest. That view actually gave some really cool footage of the dog flushing birds. It also gives you a headache when re watching the footage. One thing I would recommend is to make a note, either of the time of the day, or stop the camera and restart it (so you know the final minute of each video segment is the one with the action), so you know when to expect something in your footage. That way you don't spend hours searching through it all.
I have less time (kids) and older computer now to where I don't enjoy editing, to where I rarely use my Go Pro. Bought it in 2012 or 2013 and haven't used much since probably 2014 or 2015. Would be interested in selling it if someone is interested.
