I'll probably look into replacing the canvas with a plastic some time down the line. Still a good bang for your buck.
I trained my dog not to jump out unless I tell him to do so. This is very important, since you really don't want your dog getting out, especially in traffic. I also trained him to "kennel up", so he jumps in the trailer on command. My secret? Good dog cookies, encouragement and of course, having adopted a mutt, which are known to be smarter than most.
Have you looked at replacing the canvas with a heavier gauge cordura? If you're handy with a sewing machine, Seattle Fabrics has everything you'd need for outdoor projects. (I'm getting stuff from them to make my own courier bag and commuter backpack, as well as some ultralight camping gear.) With some cordura, vinyl window plastic and sunblocking mesh, you could make an awesome super-strong top conversion for that trailer.
