Why only one brand here

Sleepypod's Clickit Range is the crash-tested car harness with a girth chart we could confirm directly from the maker's own site. It's sold in two torso lengths, Regular and Long, at the same girth bands shown below in Regular — a long-backed dog (dachshund, corgi-type build) can need the Long version at a girth that would otherwise read as a smaller size; check sleepypod.comdirectly if that's your dog.
