Notice how he barks when he's ready to go! I was looking for videos of bigger dogs balancing on bicycles, and found this. It was awesome.
I also found a blog from 2011 which is mainly just photos, a guy rode across Australia with his faithful Kelpie on the back of his bike and raised $26,000 for the Cancer Council and the MS Society.
It's worth having a look if you want to get an idea of what the Australian outback looks like. Coffee is awesome too. Their website is called Carrot and Coffee. I would love to do a trip like that with a dog, but my dogs are 30kg each which is a lot of weight to be propelling with my weak little legs. I think I need to borrow a smaller, hardier dog for the trip.
