Yeah, I don't know if there is actually a proper way to haul a dog on an ATV. They can't hold on for themselves when the trail is rough so to me enclosed is the way to go (remember if they fall of when moving you could run them over) as far as the open concept goes. Enclosed forces them to lay down, make it small you don't want them to bounce around, pad the bottom like crazy for comfort. I use a sturdy plastic kennel, lined with a thick foam pad, that is securely fastened to my rear rack and kind of rests where my back seat goes on my Can-Am. I also drive extremely cautiously when my dog is with me no high speeds, avoid rough terrian if possible, a roll over with a dog and kennel would be good for neither you or them. Good luck on your reaserch if you come up with something real good let me know. Safe hunting.
