There's nothing in the manual about this. When I've been out for a bit and have nice warm tyres dogs appear to be attracted to them, or my feet. It's happened about four times over the last few weeks, and twice more in the last two days. I'm still developing my "dog attack" Spidey Sense, but 'dodging' dogs is rather difficult, and it's only a matter of time until one gets under my tyres.
