I've decided that I want my dog, Sofi, to ride with me. She's a medium sized Standard Poodle, 20 months old and weighs 45 pounds. I searched online for carriers that would do. The only thing I found was a $2,000 dollar custom built job. I ain't doing that. So, I decided to go my own way. Frankly, the post on here about the propane carrier top box inspired me. I've ordered a black 19X13X11 inch milk crate box. I'll cut out one of the ends, and just bungie or strap it down on top of the seat. I also ordered a foam pad for the bottom of it, and goggles for Sofi. I'll post some pics as soon as I have the little project done. I'm SO excited!
