I've always let my dog just roam free in the car (excursion or crew cab pickup) and generally he has his head out the window at speeds under about 40 mph. I have recently started kenneling him though, and it is SO nice. Especially if he is muddy and/or wet!! He has a house kennel and is trained to use it so it wasn't hard to get him used to the car kennel.
Man, haven't you guys ever seen how people can get ejected from vehicles or bash their heads in bad car crashes with no seatbelt? Exact same thing can happen to your pup seatbelt/anchor point harnesses are cheap and take 10 seconds to put on/remove
Dogs should be kennel safest place . We’ve seen some nasty post wreck patients.. dogs flung out of cars ..
Broken backs .. hip luxations… sad they get taken out in their prime by a preventable injury .
When I was younger and dumber .. dogs would ride in back seat
