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.”

Your vehicle’s cargo area likely takes a lot of abuse! Especially, if your furry passengers jump in to accompany you on errands and adventures. Protect your interior with a durable 4Knines cargo liner. We think you will prefer it to the old blanket or the “disposable” cargo liner you have been using! In fact, we guarantee it!


  • Sizing - Deciding on the best size cargo liner can be a little tricky. We are here to help!
    First, consider how you plan to use the cover. Will you attach to the front headrests or to the back headrests? Do you plan to lower one or both rear seats?
    Next, measure the length and width of area you want to cover - be sure to measure from the headrest, down the back of the seat, all the way past the bumper.
    Then, make the best decision you can based on the following information and place your order.
    Finally...if it ends up being the wrong size, don’t worry! We will be happy to help you with an exchange.
    Small (42” x 78” including 20” bumper guard) - small/compact SUVs
    Large (52” x 82” including 20” bumper guard) - standard SUVs
    Extra Large (55” x 106” including 20” bumper guard) - full-size SUVs
    Check out our sizing guide for additional guidance and recommendations

The best evaluations of our products come from the people who’ve bought them.

great cover

This is actually a replacement for my original 4 knines cover which was 4 years old. I used it daily (bringing my pup to work with me) and washed it weekly, so the backing finally started to flake apart and come off. This newer version is easier to put over the headrests, great improvement in the strap and closures. Also the best improvement is the side flaps, the old cover didn't have these. These flaps help to catch the dirt from dogs feet when they are jumping up into the car, instead of it going on the side of the seat.

This is my 2nd seat cover from 4knines and love them both. The product and service were both fantastic.


Repeat customer VERY satisfied.

We have made several purchases from 4Knines and are VERY satisfied with products (cargo liner, back seat cover, bucket front seat cover...). I volunteer at a shelter and take dogs offsite daily. Always a Pleasure doing business with 4Knines. Highly recommend.

Split Rear Dog Seat Cover - Fitted - No Hammock

I had ordered this item from an on-line site and was extremely disappointed when I received the wrong item. I was impressed with the quality of the seat cover and decided to contact 4Knines directly. I placed my order with Maggie and received the Split Rear Dog Seat Cover within three days. The seat cover fits nicely in my new Honda CR-V and as stated by 4Knines, is very easy to install and remove. My 8-month old labradoodle Brodie likes the comfort, and friends agree with him. Great quality item, reasonably priced, and outstanding customer service. Thanks 4Knines.

New truck seat cover and side panels

I really do like the seat cover and door side panels. The side panels are a must as the Beagle mix puts her feet on the doors. Every now and again someone comes up with a nice product that works well, has quality in its materials, and is well engineered. These are those. I am super satisfied.

Easy and fast install. Stays in great!! (and the dogs are happy that they get to ride along again!) :)

Ericka Spiva

Great fit, Great look, Stays in Place

I really like the look of this cover on my front bucket seat. You can't tell it's to protect the seat from the dog! It's very nice looking and fits great. Most importantly, it stays in place! My dog is wiggly, up and down, looking out the windows; and this seat cover doesn't mind. Do make sure you watch the video and carefully follow the installation instructions. I did not at first; and Support was Wonderful in helping me figure out what I was doing incorrectly.
