Vehicle Fit Guide

We put together this sizing guide to help answer some frequently asked questions. We hope it helps! – Jim and Maggie

We love traveling with our dogs. After all, they are part of the family. But much like our twin daughters, our two Dobermans are rambunctious and sometimes manage to get themselves into some nasty messes. Like you, we don’t want our dogs to destroy our vehicle's interior, so we developed a collection of luxurious “Life-Proof” products to protect our cars from muddy paw prints, claw marks, dog fur, drooling, and the dreaded “accident.”
