The Golden-Powered Trike
Biking with Chaz (left) and Boston, a rescued Golden that I'm fostering for Retrieve a Golden of Minnesota (RAGOM). Awesome Boston, as I call him, took zero time to adjust to the outrigger and harness that keeps him safely in place so I can use my left hand to steer. On my right is Chaz, who is accustomed to running alongside the trike just on a leash.
On edit: Oh dear, oh dear. I have just been informed by the guy who makes the harness system that I have the springer bolts facing the wrong direction. (The system came shipped that way and I left them there.) They should be slid down to the straight part on each side of the outrigger--even with the rings on the harness--then turned so they're facing toward the rear of the trike. So if you buy one of these from dogpoweredscooter.com, be sure you don't install it like I did! :)
