I got this platform thing off amazon per someone on a forum recommending it. A little pricy but it was worth it for our smaller dogs.

There is some weird writing on the colorful side, obviously these were originally branded gifts at some convention or some such.

It actually is kinda nice for if I need to take people in the back some times, it's strong enough that I can just pick the whole thing up with their dog beds in it and it can just be placed in the truck bed.
