I've been using bikerides as part of keeping all mine in showcondition, over the years. As long as you introduce the bike slowly, starting by walking the dog next to you leading the bike,then getting on for just a few seconds, it's no problem, really. Some take to it quickly, some need more getting used to it. As long as you stick to the same rules all the time, the dog quickly gets the hang of it. Always let your dog run on your left side, that way it's running on the pavement, with you riding in the street.( I try to do this in the evenings, and mainly ride in parks and along foothpaths. The less traffic you come close to, the better.)
No stopping to sniff when riding the bike :p that's only allowed when walking. No pulling on the lead is allowed, for obvious reasons, use a "kind" collar, not a check collar.
Those are some of my "rules" for riding the bike with my dogs, I'm sure others have different ideas, which may suit them and their dogs better.
As long as the dog isn't stressed by it, and has had plenty of time to do it's business and warm up before you start, I think it will work out fine.
Good luck,
Karen
