Anyone wishing to carry their pooch in a trailer might care to look at this video featuring a Burley Travoy trailer and a (fairly) contented looking pup.<http://www.youtube.com/watch?v=67CMhdqmPcM&feature=related>. I'm planning on getting a Travoy trailer for its utility as a cargo carrier and a shopping cart but have been concerned that I might be better off with a pet trailer to carry my middle-ageing Jack Russell around. Now I see that the Travoy can do it all even though it is a bit pricey.
