My g/f and I are adopting a beagle mix puppy (14 wks old, but not typical puppy-hyper) and I'd like to get her used to riding in a trailer while she's still young. She's going to be about 40-45 pounds when she's all grown up.
What are decent pet trailers for use with an old hardtail mtb? I've seen the Croozer (available at REI) and the Burley Tail Wagon (which I can't find a local dealer for.) Are there other pet-specific trailers?
