It's telling that we care more about our dog's safety than our own.
On rare occasions I have had my nitwit Jack Russell ride in a crate behind the seat of my bicycle. I have him tethered when I do, but more than once he has leapt out, which has him dangling pathetically against the side of the rack with a dumbstruck look on his face until I scoop him up and put him back in.
Do be sure your dog is WELL tethered if you're going to try this trick at speed on a motorcycle!
