Thank you all for the responses.
I'll try the backpack / sling approach first. Our dog is curious and energetic so I'd be most comfortable with him firmly attached to me. If that doesn't work, I'll try to rig a wicker basket. I'll test the options out on a single bike first. Being a new captain, I have enough to think about on a tandem with out a dog licking my face. I'll let everyone know how it goes.
We ride some narrow busy roads so the trailer idea makes me nervous. I've never towed a trailer but they seem dangerous outside of rail trails and lonely country roads. Agree or disagree?
ThinLine: your dogs are cute!
regomatic: sorry to hear your dog recently passed. I was strongly averse to getting a small dog but my wife talked me into it. She was right (aren't stokers always right?). He's great. At 10 lbs, he'll do anything a big dog does (while making a minimal mess in the yard
).
