I am thinking of buy a TerraTrike Rover and have a 17 lb Tweenie Dachshund I want to take along on my rides. I am wondering what kind of accessory or carrier I could get that would be most comfy and safe for us both. I do not want a run along type of setup, since she has very short legs; but something that can be setup behind the seat perhaps. Any ideas, suggestions, pictures, etc. that anyone can offer will be greatly appreciated.
