i've ridden around with a few of my dogs for years. i used to take my mini dachshund in a wire basket lined with fleece fabric, even taking her on long distance tours. i've recently graduated to a trailer that i transport my whippet and italian greyhound together in. i bought a "wike" trailer and i really like it a lot, as do the two dogs. i put a fake sheep skin pad down on the floor and they seem very comfy, and they are securely harnessed to tie ins provided by the company. they look so cute, people just love seeing them, i get lots of smiles and waves. i get lots of room from passing motorists too; i'm sure they assume there are children in the trailer. anyway, wike trailers have different sizes of trailers and are very easy to hitch to the bike (or recumbent trike in my case). the trailer seems very well constructed. i found mine slightly used on craig's list! anni
