Why such a bold guarantee? Because as fellow big dog owners, we know exactly what these covers can handle. While cheap overseas knockoffs fall apart in weeks, ours stands the test of time.

Frequently Asked Questions

Our universal design fits all major SUVs, trucks, and crossovers thanks to adjustable straps and anchors.

The RUFFGUARD MAX™ adapts to both bench and split-fold seats, with extra coverage for taller vehicles.

Installation takes just 5 minutes.

Engineered specifically for large breeds like German Shepherds (100+ pounds). Our military-grade materials withstand jumping, clawing, and heavy impact.

Reinforced stress points and double-stitched seams prevent tears where big dogs put the most pressure.

Machine wash in cold water with mild detergent when needed. For quick cleanups, vacuum hair or hose off mud.

Our waterproof fabric dries fast without losing protection. Weekly vacuum and monthly deep clean recommended for best results.

Our triple-layer protection system blocks water, mud, and accidents from reaching your seats.

Beach tested with wet dogs and lake-proven. Unlike cheap covers that soak through, our hard bottom back seat extender keeps seats completely dry.

Standard 1-year replacement warranty covers tears, rips, or damage. Upgrade to lifetime protection for $49.

All claims handled by our US-based team in Georgia – not overseas call centers like the competition.

The RuffGuard Max™ can hold up to 350lbs, so multiple big dogs can be in the back at once.

It fit perfectly, is incredibly sturdy, easy to sweep off and wipe down, created a safe and spacious back area for our two pups and their quite large dog bed. The mesh panel is solid. The zippers are solid. It protected the doors and still let our pup stick her head out the window. Spill and water proof. It doesn’t hold onto fine dog hairs like some fabric. The pockets in the back made accessing their travel water bowl, dog bags & leashes super easy. It’s also nice looking which, I’ll be honest, is a big selling point for me. I 100% would recommend and would purchase again in a heartbeat.

I have a 65+ pound German Shepherd mix. I was worried no matter what cover I got it wouldn't support him. This cover has exceeded my expectations. I loved that it extends all the way to the back of the front seats. The door covers we usually keep folded under the base of the matt, but when we have used them they were very handy. It's a great addition to our vehicle and has saved our leather seats over and over again. I especially like that it fold up so easily, unlike other soft covers we've had that we would result to curling up in a ball and tossing onto a shelf in the garage. It's so easy to install and clean. It can be a little slippery for our dog (his balance is questionable though). I have thrown a blanket on it from time to time when we do long trips, but otherwise he finds it quite comfortable.

This invention is genius. Our 64lb super mutt love riding in the back seat with the gap between the front and rear seat firmly covered. This thing is sturdy, will support 100 pounds easily. Covers the gap between the front bucket seats to keep her in the back seat. Space under the overhang has easy access storage that’s dog proof.

First, it's extremely stable and spacious for our medium sized border collie. Even big enough to fit her bed in fine. My parents have a basic hammock and the hard base on this makes it a completely different beast. Although you pay for it, it's worth it. I have a pickup so it also doubles as a safe spot to load groceries. It fits very well in my 2020 Chev Colorado.

I bought this because my 120lb rottweiler is too big for my back seat, and he was slipping off constantly. When I would pick him up from doggy camp, he would try to nap and would be rolling off the seat so fast.

He LOVES this extender. He is able to sit, lay, and move around in the backseat as he needs to. The middle mesh area let's him rest his chin and stare at us in the front seat and keep close for cuddles. The cushion is also NOT slippery at all. He is able to sit comfortably to poke his head out the windows, or take a nap on the way home. I thought it was pricey at first, but now I need to buy a 2nd one for my partner's car.

It's also a super easy set up / take down when we switch cars, and it's waterproof! It has seen many a pup cup castrophe and still looks great.
