Great investment
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
I have a 45lb shiba inu mix and he loves this so much! Fits my Kia forte perfectly, very durable and easy to install and store if you need your back seat for people. Looks great, easy to wipe down or vacuum, zipper is sturdy and the padding is comfortable for him and it helps him feel sable through the ride. Water resistant for muddy paws or spills. ... show more

Fits well and looks great!
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
This fits our 2025 Hyundai Tucson great! It is made of high quality materials and our dogs like it. I would definitely recommend it. It makes us feel safer while riding with our dogs. Their seat belts clip into the easy open slots and It is easy to install and protects the seats and the door handle rest very well. We love that it can easily be folded up. We are very happy with this purchase! ... show more

Full coverage and great quality
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
Love this! Have had others before but this one is way better quality! Fits the back seat of my 2026 VW Tiguan perfect- love the hard bottom with the ability to fold up when needed. Also LOVE how it protects the sides of my car doors. Will update once my 87 lb boy tries it out. UPDATE- had my dog in my new car and this seat protector works flawlessly! He hasn’t slobbered on any part of my car - he loves the mesh in the front so he can still get air from the ac. Construction is great - 87 lbs in and out - the side door protector zips down to allow him easy access and covers my door edge to prevent scratches. Love this! ... show more

Good Overall, but My Puppy Chewed the Strap on Day One
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
The PETICON back seat extender works really well and makes car rides much safer for my dog. The hard bottom is sturdy, fits perfectly across the back seat, and keeps my puppy from falling into the footwell. It’s comfortable and easy to clean, and installation was simple. The only issue I had is that my 5-month-old puppy managed to chew one of the straps on the very first day. The material of the extender itself is strong, but the strap wasn’t tough enough for a teething puppy. I still think the product is great, just make sure to keep the straps out of reach if you have a heavy chewer. Overall, it’s very useful and makes traveling with a dog much easier. ... show more

Great buy, wish I would have bought sooner.
Color: gray Size: M - 51"W - Compact Cars & Subcompact SUVs
Great seat cover and our dog loves it. Sturdy, easy to install. Allows access to seat belt buckle for dog seat belt. Saves my leather seats and still allows our dog window access. No more sand on seats from going to the beach daily. Waterproof which is great our dog loves the ocean and lakes.

WARNING: This Almost Lasted as Long as My Patience
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
I bought this backseat “extender” barrier and tether specifically for our 9-month-old, 50-pound, three-legged rescue puppy. She's sweet, not aggressive, she's just... determined and this product was no match. For the first couple of hours it seemed okay. She rested her face in the center gap, looking like the cutest thing ever. I relaxed, thinking we'd cracked the code for safe car travel, but then she decided she needed to join us up front for some quality time. The seat belt tether was the only thing holding her back, so she just chewed right through it in under a minute, clean snap, no hesitation, shoved the barrier down like it was tissue paper, stepping right over and voila! (did I mention she also was wearing TWO giant donuts around her neck! 😳) We were on a highway in the middle of nowhere with about 14 hours of driving left and this adorable tri-pawd puppy is now in the front seat, sprawled across the console, tail wagging like "Oh hey, this is my spot now." She's only 50 pounds, missing a front leg and wearing not one but TWO donuts around her neck.. I’m no expert, but this should not have been possible. The barrier itself is very flimsy and the tether/seat belt? Even worse! (apparently made of material tasting like freedom and snuggles to a determined puppy.) If your dog is a calm, perfect angel who never questions the rules, and doesn’t move, maybe? If your dog is even the slightest bit of anything else, do not waste your money, not worth the stress, safety risk or using your arm as a barrier for the remainder of a commute. Mia says 1 star for being boring. I say 1 star for almost giving us a heart attack.🐾🚗💨 ... show more

Great ...
Color: black Size: M - 51"W - Compact Cars & Subcompact SUVs
I got the car seat extender and was super excited because my dog is a bit nuts back there, and she has severe vision issues, which makes it very difficult for her to tell where she can step or can't step when the car is moving. This seat extender not only made it safe for her to move anywhere around the backseat, but it also showed her clearly where her space ended so she wasn’t trying to climb into the front seat. The part that blocks her is mesh, so the air still gets back there, and I can see her just fine, which is really great. At first, I was a little disappointed when I saw that the boards on the bottom are squares instead of rectangles, thinking that would make it not as strong, but I haven’t had any issues with my 60-plus pound dog running around the backseat. They spaced it properly so that they’re still very strong and do exactly what they’re supposed to do. Not to mention the fact that the mess—the hair, the water, the mud, the toys—everything stays in one easy place. Easy to clean up, easy to take out. ... show more
