How can I attach a camera to a dog's head without restricting his breathing or causing discomfort?

I am asking this because I would like to get an idea of what the family dog sees when we are playing fetch.

The dog is called Clipper, he is half Pitbull half Argentine dogo, and he likes extreme games of fetch. He is the most athletic thing I have ever seen, and he must see the world in a very unique way when we play fetch.

I have seen some cameras online for this purpose, but I think they would restrict his breathing. I am trying to think how I could attach a camera to his head for 5 to 10 minutes without bothering him, any ideas?

He is very muscular, so needs to have his mouth fully open to take in air, and it needs to be comfortable or else he will just take it off or destroy it.

The only reason I want to do this is because he runs at about 40mph, jumps 2 meter walls without touching them, and he slides in the dirt like a rally car when he is slowing down to grab the ball. I thought it would make for an interesting video.

Any ideas?
