Easy now people!
Yep, it would be stupid to put a dog in the back of a Zed, even for a short journey. Even if you're not fussed about the comfort of the dog, there is nothing stopping it from flying through and smashing your head to pieces in an accident. Think about it..... If you are concerned about the dog, you wouldn't even entertain the idea.
That said, I can't find the thread, try some advanced searches.....
