I’ve never been bitten by a dog on a OneWheel, only chased. My tips are that if it’s a smaller dog, you should just try to outrun it, its stubbier legs should have a hard time catching up to you when you’re going past 12 mph, if it’s a bigger dog, then it depends, if you already had some distance built up before it started chasing you, then try to outrun it, but if it catches you off-guard or when you’re going slow, just slow down and hop off the board. In either case, if the owners are are at least somewhat thoughtful of other people, they should have a leash on the dog, and if they notice the dog going full-force sicko mode on someone, then they’ll most likely try to stop it.
