I agree with SLK...that thing looks like SO much fun! I can just see Bridgette tearing off in the wrong direction and seriously hurting the both of us though...lol.
That's awesome! I scooter with my dogs too, but they pull out in front of me. Howeverm, this looks like a better set up for city riding and a little safer.
I think these look dangerous- I really don't think a side-setup like that is going to put even pressure on the dog's spine, especially since you can't flip it from side to side so as not to use it the same way all the time. And it's so wide you couldn't ride it on bike trails without taking up a lot more space and being harder to pass.
