Why big dogs hate the back seat

Big dog, small back seat? Give them the whole floor.

A bench seat is too narrow for a big dog to lie flat, and the footwell gap is a trap. On every turn and every stop, they slip or step into it.

A hard-bottom extender bridges the gap with rigid panels, so your dog gets a flat, stable deck about the size of a bed. Your seats get a waterproof shield, and you get eye contact through the mesh window.

Sound familiar?

  • Your dog slips or steps into the footwell on turns
  • Your dog paces and won't settle on long drives
  • Hair woven into the seat fabric
  • Claw scratches on leather or doors
  • A cleanup after every park, trail or beach trip

Safety first: this extender is not a crash-tested restraint. Always secure your dog with a harness and a seat-belt tether, and never let them ride in the front seat.

Room for one big dog, or two

Room for one big dog, or two

The footwell is wasted space. Bridge it and the back of your car becomes floor your dog can actually use.

  • ✓

    One big dog stretches out flat instead of curling up on the seat

  • ✓

    Two dogs share the deck without one ending up on the floor

FAQ

Before you buy

Still unsure? Email us your car's make and model and we'll tell you honestly whether it fits.

Email us
Will it fit my car?

Size L (52" wide × 26.8" front to back) fits most sedans, mid-size SUVs and small trucks. Size XL (57.4" wide × 31.2" front to back) is for full-size crew cab trucks (Ford, GMC, Chevy, Toyota, RAM) and full-size SUVs. Email us your year, make and model and we'll confirm before you order.

How much weight can it hold?

The hard-bottom panels are rated to 400 lbs by the manufacturer, so a big dog can stand, turn and lie down without it sagging into the footwell.

Can two dogs ride on it?

Yes. Because the footwell becomes usable floor, two medium or large dogs get more room than the seat alone. For two big dogs in a truck or full-size SUV, choose XL.

Does my dog still need a seat belt?

Yes. The extender gives your dog a flat, stable spot, but it isn't a crash-tested restraint. Always use a harness and a seat-belt tether.

Will it slide around?

Straps buckle around the front and rear headrests and the seat anchors tuck into the seat crease, so it stays put on turns and stops.

Can people still sit back there?

Yes. Unclip it and lift the hard panels out in about a minute.

How do I clean it?

Wipe it down or hose it off. Slide the hard panels out to wash the cover on its own.

How fast does it ship?

Shipping is free and tracked. Most US orders arrive in 3 to 7 business days.

What if it doesn't work for my car or dog?

Try it in your car. You have 30 days from delivery to return it, even after installing it, as long as it isn't damaged and all the parts and packaging are included. Email us your order number first. Details are in our return policy.

Very good, fits well with the car (SUV type).

Cierra Kutch

Very good for transporting my dog without damaging the leather interior.

Excellent quality. Looks good in the car interior. You can fold one section and sit next to it.

D
Dori Mosciski

So worth it, quite decent for the price

V
Venetta Bruen

Excellent product, arrived quickly!! Finally something that keeps the car clean and lasts a long time.

I have a hyundai suv. fits very well across the back seats, and the clips that go around the head rests secured it pretty well. also came with a leash that goes right into the seat belt thing that secures my dog really well, but it's a very small clip for their collar so probably wouldn't work for a larger dog. the bottom panels cover the far and are pretty solid. haven't tried yet but looks like the panels can be removed and you can throw the whole thing in the wash. was delivered in a couple weeks so no complaints

Great product! unlike similar items it’s very durable and feels like it’s going to last. recommended.

G
Geraldine Keeling

better than I expected

Q
Quintin Veum

A slightly smaller size would have been better for the light vehicle.
It was a bit too big.
Next time, I will measure the size before placing an order.

A
Alphonso Quigley

You have a very good car cover that is durable and waterproof. It has hard plastic plates in three sections on the seat that provide firm support. The product is very good, I like it.

K
Kirby Gusikowski

Although it took almost a month for the product to arrive, it is of very good quality, so the wait was worth it. It has just the right amount of rigidity, fits the car well, and my two medium-sized dogs don't slip when getting in. Highly recommended.

A
Al Goyette

Pretty good, but the hard part of the cover where the dog steps is made of plastic plates and it's not as hard as I expected.

H
Hiram Bauch

Only 1 opening for seatbelt

D

Perfect item and highly recommended to everyone.

V

The product is good, but there is no belt to hang on the back seat door.

Excellent! Better than i imagined.
