Bought a motorcycle trailer last year to tow behind the Trike. I would like to see if anyone has ever used a trailer for taking their pets along with them. I know that there are the Wags trailers for pets. They are way too expensive for my budget. My trailer is much like a clam shell. Does anyone have ideas or have you made one? I would like to see pictures if possible. My husband could do the work. He will cut a hole in the top but we need something that will allow the 2 small-med sized dogs from being able to put their heads up to look about while not allow them to jump/fall out. We will also want to be able to convert it back to a regular trailer as well when needed.
