Dog + Bike question

[aly]

We just rescued another German Shepherd Dog. She was SUPPOSED to be a foster, but... well you know how that goes. She is very good a little bit of the time, and absolutely insane a lot of the time. She's about 10 months old and full of energy. So, I've started riding my beater/cruiser with her on a springer attachment. Right now, we only do a couple of miles.

I was wondering if anyone else uses one of these and how far you generally go (and in what sort of weather). I'm in SoCal, so we'll avoid riding when temps get too high. Anyone have any experience or advice?

Oh, and here are some pics of the new girl!!
