Cycling with Calen (my dog)

How can I bring my pup along for those all-day long rides?

I've found a good thread and yet another about bike trailers. I've also researched some models (DoggyTote, Chariot Carriers, WIKE, DoggyRide, PetTrailer, TailWagon, Croozer, Burley Trailer, Roland Trailers, Trek'r Pet Trailer, Dog Bike Trailer) online so far. I'm going to see if I can't get my hands on--and my doggie into--one of these sooner than later.
