I have a large plastic Vari kennel I use in the back of truck to haul my setter, he fits fine and can stand up in it. My question is: I have a chance to buy an aluminum kennel for the back of truck with top storage, my dog will not be able to stand all the way up in it though, he will have plenty of lay down space, do any of u run short kennels for hauling dogs, I know to stop every couple of hours and let him out when on a road trip but still concerned if it is too short!
