Hi and welcome. We had a dog in the 80’s that came running out when it heard the bike starting and it would jump up and sit on the tank. It wouldn’t move until I took it for a run up the road and back, even made it into the local newspaper. You could get away with these kind of things here in these days, but not now.
that's what mine does! I take him outside, and if he sees one of my bikes with his dog bed on the tank he runs to it, jumps up on the seat, then walks into the dog bed, and gets comfy for the ride. sucks that it's illegal in UK! in California our courts already ruled back in 1996 on this issue: totally legal (https://www.latimes.com/archives/la-xpm-1996-02-22-me-38569-story.html).
