Dog Car Seats: Everything You Need to Know
Some companions only truly relax on the road when the car finally feels like theirs. This guide covers everything you need to know about dog car seats — which seat suits small dogs, what a booster seat actually does, an honest look at safety, sizing by inner dimensions, console seats, large dogs, installation, and care — so you can choose once, and choose right.
Key Takeaways
- For most small dogs, the best car seat is an elevated, patented design like the Companion Car Seat® — the dog sits about 7" above the base for a window view, and the seat integrates with your vehicle's seat belt system.
- Fit is decided by inner dimensions, not weight alone. Weight ranges are a safety guide; map the inner resting area on the floor around your dog and size up when in doubt.
- Honest safety framing: Animals Matter® car seats are engineered with dual utility patents (Nos. 7,717,062 & 7,574,975) and secure with the seat belt and a harness tether. They are comfort-and-containment seats, not certified crash restraints.
- Two patented designs cover most travelers: the back-seat Companion Car Seat® (Standard to 20 lbs., 2X to 30 lbs., 3X to 45 lbs.) and the Companion Car Seat Console® for very small dogs up to 12 lbs.
- Built to last and to wash: CertiPUR-US® certified foam components, dense upholstery-grade construction, and a removable Micro Velvet cover that machine washes cold — artfully hand crafted in California.
What is the best car seat for small dogs?
The best car seat for small dogs is an elevated, structured seat that raises the dog high enough to see out the window while keeping them contained. The Companion Car Seat® Standard fits dogs up to 20 lbs., seats them about 7" above its base, integrates with the vehicle seat belt, and clips to a harness.
Small dogs benefit from elevation more than any other feature. Riding low on the bench, a 10-pound companion sees nothing but seat backs and sky — a common source of restlessness. Elevated in a defined space with a view of the road, most small dogs settle, watch, and eventually doze. The scoop front of the Companion Car Seat® also gives shorter-legged companions an easy step-in entry. For the full lineup of sizes and styles, explore Dog Car Seats.
What is a dog car booster seat?
A dog car booster seat is a raised travel seat that elevates a dog for visibility and a defined riding position. The Companion Car Seat® functions as a premium booster seat: the dog sits about 7" up from the base, high enough for a window view, inside supportive foam walls that integrate with the seat belt.
The term "booster" describes the elevation; what surrounds that lift is what matters. Mass-market boosters are often thin foam shells hung from a headrest that sway with the vehicle and flatten within a season. A structured booster built on dense, upholstery-grade foam keeps a stable base under the dog through turns and stops, and includes an attachment strap that clips to your companion's harness — never a collar. A second attachment is available for compatible sizes carrying two small companions.
What is the safest dog car seat?
The safest dog car seat is one that secures to the vehicle itself, not just to the dog. Animals Matter® car seats are engineered with dual utility patents (Nos. 7,717,062 & 7,574,975): a recessed groove routes the lap belt around the seat, the shoulder belt secures the back, and a tether clips to the dog's harness.
That three-point logic — seat belted to the vehicle, dog tethered to the seat, tether on a harness rather than a collar — keeps a companion in a defined position instead of roaming the cabin, climbing toward the driver, or sliding off the bench at a hard stop. A contained dog is also a smaller distraction, which protects everyone in the car. We are equally direct about what a car seat is not: it is a comfort-and-containment product, not a certified crash-restraint system. For best practice, ride in the back seat, use a properly fitted harness, and pair the seat with an appropriate pet vehicle restraint.
How do you choose the right dog car seat?
Choose a dog car seat by three factors: your companion's size and resting posture, your vehicle's layout, and the kind of ride they need. Dogs who relax and watch suit the scoop-front Companion Car Seat®; very small dogs who ride best close to you suit the Companion Car Seat Console®.
Their travel personality is usually obvious after one honest drive. Does your companion press toward the window, circle and curl, or try to migrate into your lap? Match the behavior to the design:
| If your companion… | Consider… |
|---|---|
| Enjoys an elevated view with room to relax and curl | Companion Car Seat® |
| Is very small (up to 12 lbs.) and likes to ride close, between the front seats | Companion Car Seat Console® |
| Needs more rear-seat surface area to stretch out | Companion Backseat Extender® |
| Wants the "which model is best" comparison | Best Luxury Dog Car Seat: An Honest Buying Guide |
Once the style is settled, confirm fit with the Inner Resting Area fit method below — the step most buyers skip, and the one that matters most.
What size dog car seat does my dog need?
Size a dog car seat by its inner dimensions — the usable space where your dog actually sits — not by weight alone. Stated weight ranges are a safety guide. Map the inner width and depth on the floor around your companion as they naturally settle, and size up when between sizes or in doubt.
This is the Inner Resting Area fit method Animals Matter® uses across every product: fit the space to how the dog rests, not to the number on the scale. Use these real per-size specifications:
Companion Car Seat® (back seat, scoop-front)
- Standard — for dogs up to 20 lbs. Outer 16"W × 21.5"D × 16"H; inner 12"W × 14.25"D × 7.5"H, sloping to 4"H at the front scoop.
- 2X — for dogs up to 30 lbs. Outer 20"W × 21.5"D × 16"H; inner 16"W × 14.25"D × 7.5"H, sloping to 4"H.
- 3X — for dogs up to 45 lbs. Outer 28"W × 22"D × 16"H; inner 24"W × 14"D × 8"H, sloping to 5.25"H. Installs on bench-back seats only.
Companion Car Seat Console® (center console)
- Sport Console — for dogs up to 4 lbs. Outer 9"W × 15"D × 7"H; inner 5.5"W × 12"D × 6"H.
- SUV Console — for dogs up to 12 lbs. Outer 12"W × 19"D × 8"H; inner 9"W × 15"D × 7"H.
Across every back-seat size, the dog sits about 7" up from the base — the elevation that gives smaller companions their window view.
What is a console dog car seat?
A console dog car seat is a compact, elevated seat that installs on a vehicle's center console — not on a vehicle seat — placing a very small dog between the front seats, close to you. The patented Companion Car Seat Console® fits dogs up to 12 lbs. on compatible consoles.
It is the right answer for tiny companions who calm the moment they can see you. The Console is built with custom Companion-Pedic® foam made in Southern California, straps around a console lid that opens from the side or front, and includes the same harness-attachment strap as the full-size seats. Console shapes vary by vehicle, so confirm your console style and the inner dimensions before ordering — the product page covers compatibility in detail.
Is there a dog car seat for large dogs?
Dogs up to 45 lbs. fit the Companion Car Seat® 3X, which installs on bench-back seats with an inner resting area of 24"W × 14"D. For companions over 45 lbs., a car seat is the wrong tool — a backseat extender creates a broad, continuous platform across the rear seat instead.
We would rather tell you this plainly than sell an oversized seat that cramps a big dog. The Companion Backseat Extender® fills the rear footwell so the back seat becomes one level, cushioned surface where a larger companion — or more than one dog — can stretch, reposition, and rest, always paired with a properly fitted harness.

How do you install a dog car seat?
Animals Matter® back-seat car seats install using your vehicle's existing seat belt: the lap belt routes through a recessed groove around the front of the seat, the shoulder belt secures the top back, and the included tether clips to your companion's harness — never a collar.
- Place the seat on the rear bench and route the lap belt through the recessed front groove.
- Buckle and secure the shoulder belt across the top back of the seat, then tighten until the seat sits firmly without sliding. (The 3X installs on bench-back seats only, with the shoulder strap through the center-back loop.)
- Clip the attachment strap to your companion's harness.
- Use the same position each trip so your companion learns to associate the seat with calm travel.
The Companion Car Seat Console® installs differently: open the console lid, wrap and tighten the bottom straps around the lid, and close it to lock the seat in place. Product-specific instructions ship with every seat.
What are dog car seats made of, and how do you care for them?
Animals Matter® dog car seats are built on dense, upholstery-grade foam with CertiPUR-US® certified foam components, wrapped in a removable padded Micro Velvet cover of 100% micro-denier polyester. The cover unzips for cold-water machine washing and line drying; foam and inserts spot clean with half white vinegar, half water.
Density is the quiet difference between a travel piece that lasts and one replaced every season: dense foam holds its structure through years of daily rides, where lower-density alternatives flatten within months. The velvet is colorfast and abrasion-resistant — made for real errands and real road trips. Every seat is designed, developed, and artfully hand crafted in California, with select textiles and components thoughtfully sourced from trusted U.S. and global mills. Animals Matter began with our founders' own dogs, and every design still starts with the same question: would my dog choose this?
How do you help your dog ride calmly in a car seat?
Introduce the car seat gradually: start with five-minute neighborhood drives and extend the time as your companion settles. Feed a light meal no closer than three hours before departure, stop for regular breaks on long trips, and keep identification current in case you are separated at a stop.
A few more habits from two decades of traveling with companions: skip treats and chews in a moving car, keep air circulating on the sunny side of the vehicle, bring one familiar toy, and never leave a dog in a parked car. Most dogs learn to love their seat within a handful of drives — the consistent place, the elevation, and the view do most of the training for you.
Choosing with confidence
The right dog car seat matches how your companion actually rides — the view-seeker, the close-sitter, the sprawler — confirmed by inner dimensions and secured with the seat belt and a harness.

Frequently Asked Questions
Are dog car seats crash tested?
Animals Matter® dog car seats are not marketed as certified crash-tested restraints, and we believe honesty matters here. They are patented comfort-and-containment seats (Patent Nos. 7,717,062 and 7,574,975) that integrate with your vehicle's seat belt system and clip to a fitted harness. For restraint, pair the seat with an appropriate pet vehicle restraint and follow its manufacturer's instructions.
What is the best car seat for a small dog?
The Companion Car Seat® Standard suits most small dogs up to 20 lbs. It elevates your companion about 7 inches for a window view, integrates with the vehicle seat belt, and includes a strap that clips to a harness. Confirm fit by the inner dimensions — 12"W x 14.25"D — rather than weight alone.
What size dog car seat does my dog need?
Size by inner dimensions, not weight alone. The Companion Car Seat® comes in Standard (to 20 lbs.), 2X (to 30 lbs.), and 3X (to 45 lbs.); the Companion Car Seat Console® fits very small dogs (Sport to 4 lbs., SUV to 12 lbs.). Map the inner dimensions on the floor and size up when in doubt.
Can a dog car seat be used in the front seat?
The back seat is the safer place for a dog to ride because of front-seat airbags and proximity to the windshield. The one exception is the Companion Car Seat Console®, designed for very small companions to ride between the front seats on a compatible center console.
Do dog car seats help with car sickness or anxiety?
Many dogs settle more easily when they can see out the window, and an elevated dog car seat raises them to that view. Results vary by dog, but the combination of visibility and a defined, contained space can ease restlessness and motion discomfort for uneasy travelers.
Are dog car seat covers washable?
Yes. The cover unzips for cold-water machine washing and line drying — no heat, bleach, or bleach alternatives. Foam and inserts are not machine washable; spot clean them with a solution of half white vinegar and half water and air dry.
What is the difference between a dog car seat and a dog booster seat?
A dog booster seat is any seat that elevates a dog for visibility; a structured dog car seat adds supportive foam walls, seat-belt integration, and a harness tether. The Companion Car Seat® does both — it boosts your companion about 7 inches while providing a patented, contained travel seat.
