THE HENDERSON'S 90-DAY "LOVE IT OR HIT THE ROAD" GUARANTEE

Take your dog on every adventure for 90 days. Beach trips, muddy hikes, daily drives – put our cover through real-life testing.

If it fails you in any way – or you're just not 100% satisfied – simply email us and we'll promptly refund your entire purchase price. No need to ship it back, no complicated return process, no "handling fees."

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.

Plus, every cover comes with our standard 1-year "You Break It, We Replace It" warranty. And for total peace of mind, upgrade to our lifetime protection for just $49.

That's the Henderson's difference – we stand behind our products.

Frequently Asked Questions

Will it fit my vehicle?

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.

Can it handle big dogs?

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.

How do I clean it?

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.

Is it truly waterproof?

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.

How does the warranty works?

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.

How much weight does the RuffGuard Max™ support?

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