📏 Sizes & dog weights
S up to 15 lbs · M 15 to 35 lbs · L 35 to 50 lbs · XL 50+ lbs or two dogs. Go by weight, not by breed. Between two sizes? Take the larger one so your dog can turn around and lie down.
🐕 Why do I need a dog car seat?
A loose dog slides across the seat at every turn, climbs into the footwell, and pulls your eyes off the road. This seat raises your dog so it can see out of the window and keeps it in one place, clipped to its own harness.
🚗 Driving with your dog in the US ⚠️
There is no federal law, but three states require restraint: New Jersey ($250 to $1,000), Rhode Island (up to $200) and Hawaii ($57 to $97). Nine more can cite an unrestrained dog under distracted-driving laws. Everywhere else it is not required — it is simply safer.
⚓ Does it fit my car? ISOFIX / LATCH
Yes. Metal ISOFIX / LATCH clips lock onto your car's lower anchors, and adjustable straps loop around the headrest. Sedan, SUV or truck, it is the same seat.
🐾 Can two dogs fit in one seat?
Yes, in the XL — it is built for two dogs travelling side by side, or one large dog that likes to stretch out. For two small dogs, two S seats also fit across a back seat.
🧼 How do I clean it?
The cover comes off and goes in the machine on a cold cycle. The waterproof outer wipes clean, and the non-slip base keeps the seat where you put it.
🛡️ Is it crash-tested?
No, and we will not pretend otherwise: no US standard exists for dog car seats. This is a containment and comfort product — it keeps your dog in place and stops it distracting you, which is what matters on the vast majority of drives.

Size XL - for big dogs over 50 lbs, or for two dogs travelling side by side.

The XL is the seat for Labradors, Golden Retrievers, German Shepherds and other big dogs, and for two small or medium dogs sharing one bed. It gives a big dog room to stretch out, with walls to lean on and a view out of the window.

What you get

  • ISOFIX/LATCH clips - metal clips lock onto your car's anchors so even a heavy dog does not shift the seat.
  • Double-sided cushion - plush fleece on one side for winter, smooth waterproof fabric on the other for summer. Flip it with the season.
  • Metal safety clips - they attach straight to your dog's harness so it stays on the bed instead of climbing into the front.
  • Adjustable straps with quick-release buckles - the seat loops around the headrest and clips shut. By hand, no tools, and it moves from one car to another in a minute.
  • High padded sides and backrest - your dog can lean and lie down without slipping into the footwell.
  • Non-slip base - the seat stays where you put it.
  • Removable, machine-washable cover - waterproof outer, wipe it clean or put it in the machine.

Choosing your size

S up to 15 lbs · M 15 to 35 lbs · L 35 to 50 lbs · XL 50+ lbs or two dogs. If your dog is between two sizes, take the larger one so it can turn around and lie down. Unsure? Email us your dog's breed and weight.

Free shipping, ships in 24 to 48 hours.

Which breeds fit the XL

Go by weight, not by breed name. The XL is built for dogs from 50 lbs (23 kg) upward, or for two smaller dogs travelling together:

  • Labrador Retriever
  • Golden Retriever
  • German Shepherd
  • Boxer
  • Greyhound
  • Weimaraner
  • Siberian Husky (large male)

It is also the size to pick for two small or medium dogs who travel side by side - two Frenchies, two Dachshunds, a Jack Russell and a Pug.

Common questions

Is a dog car seat safe? A loose dog is the risk: it can climb into the footwell, jump to the front, or be thrown forward under braking. This seat keeps your dog in one place, sitting up, with a clip for their harness so they stay put. It is a comfort and containment product, not a crash-tested restraint.

Which seat should it go on? The back seat. On a front passenger seat an active airbag is dangerous for a dog, exactly as it is for a child.

Will it help with car anxiety or motion sickness? It is not a treatment. But it raises your dog so they see out of the window instead of the back of a seat, and being able to see the road ahead settles a lot of restless dogs.

Can the cover be washed? Yes. The cover is removable and machine washable, with a waterproof outer you can simply wipe down.

XL dog car bed, booster seat or seat for 2 dogs?

All of these. People search for it as a large dog car seat, dog car bed, pet car seat for 2 dogs, elevated dog car seat, dog car pillow seat or dog travel bed for the car. It is the padded, raised version that also anchors to the car and clips to your dog's harness, sized for big dogs and for two dogs side by side. Every name explained · Dog car seat for trucks.
