Best Large Dog Crate For Car Backseat: Compare 10 Travel Options

#1 · Best Overall

1. PetSafe Happy Ride Crate

• Dimensions: 27"L x 19"W x 28"H
• Material: Aluminum
• Dog Breed Size: Large

Best for: Single-seat ventilated travel crate.

Why it ranks #1: Designed to occupy one seat, it includes a headrest strap and seatbelt slits, two doors, and a stated 60-pound maximum weight recommendation.

Two entry doors let a dog enter from either side of PetSafe’s travel crate, a useful option when access depends on which side of the car is available. Mesh across the front and sides adds ventilation, while the one-seat footprint leaves room for another passenger on the back seat.

The headrest strap and seatbelt slits help hold the crate in place, while two drawstring openings let you offer a treat or pet your dog without using either door. That can simplify brief interactions during a stop. Inside, the cushioned pad has a removable waterproof fleece cover, making care more convenient. At 27 inches long, 19 inches wide, and 28 inches high, it occupies one seat rather than extending across the rear bench.

Skip it if you need an extended platform for a dog to stretch beyond the seat; Sintuff’s Enclosed Extra Large Dog Car Seat adds backseat floor space.

This suits owners who want a ventilated crate on one backseat position, especially when two-sided entry and passenger space matter. Check the 60-pound limit and 27-by-19-inch footprint against your dog and seating arrangement.

#2 · Best Metal Frame

2. Snagle Paw Portable Car Crate

• Dimensions: 26.77"L x 23.62"W x 24.8"H
• Material: Metal, Oxford cloth
• Dog Breed Size: Large

Best for: Metal-frame backseat restraint.

Why it ranks #2: Specifically secures to the rear seat with a seat belt and adjustable top straps; its non-collapsible metal frame measures 26.77 by 23.62 by 24.8 inches.

A non-collapsible metal frame is the defining feature of Snagle Paw’s car crate, giving the enclosure a rigid structure for rides. Seatbelt and adjustable headrest straps secure it to the rear seat, while its 26.77-by-23.62-inch footprint suits buyers who want a portable, large-size travel crate with a supported floor.

The metal frame and hard mat support address two practical concerns: the structure is intended to resist shaking, and the mat helps prevent sagging while the dog lies down. A soft overlay adds a second comfort layer. When the crate is not needed, its brackets fold and fit into the included storage bag, making trunk storage more manageable. At 26.77 inches long and 24.8 inches high, it is a defined backseat enclosure rather than a full-seat extender.

Skip it if you need room beyond the rear-seat edge for a large dog to stretch; Sintuff’s Enclosed Extra Large Dog Car Seat has an extended platform.

Choose this for a large dog within the 20 kg recommendation when a rigid, strap-secured backseat crate and pack-away brackets suit your trips. Its specified dimensions and weight limit remain important boundaries for your dog and vehicle.

#3 · Best Adjustable Fit

3. Petsfit 36-Inch Travel Crate

• Dimensions: 36"L x 24"W x 23"H
• Material: Oxford Cloth+Waterproof Bottom+Alloy Steel Rods
• Dog Breed Size: Large, Medium, Small

Best for: Adjustable sloped car fit.

Why it ranks #3: Its car-specific sloped design and adjustable structure address vehicle fit, while the 36-by-24-by-23-inch crate has a 70-pound maximum recommendation.

A sloped shape is intended to follow the angles of car seats and trunks, distinguishing the 36-inch Petsfit crate from boxier travel kennels. Its adjustable structure pairs with a single-piece support frame, offering a way to adapt the fabric cover and frame while keeping the soft-sided enclosure foldable for storage.

The adjustable structure is described as addressing compatibility between the fabric cover and stainless steel frame, which can make setup more straightforward. A single-piece support frame avoids folding directly at the middle, while the sloped profile suits angled vehicle spaces. Oxford cloth, a waterproof bottom, and alloy steel rods form the listed construction. At 36 by 24 by 23 inches, with a 70-pound maximum recommendation, it offers a defined size and load boundary for car travel.

Skip it if you have only one seat available for a crate; PetSafe’s Happy Ride is described as occupying just one seat.

Choose this for car travel where an angled fit, adjustable structure, and 36-inch interior footprint align with your vehicle. The 70-pound maximum recommendation and longer form are key limits to check for your dog and available space.

#4 · Best Seat Extender

4. Sintuff Enclosed Extender Seat

• Dimensions: 35.43"L x 23.62"W x 23.62"H
• Dog Breed Size: Large

Best for: Backseat space extender.

Why it ranks #4: The backseat extender reaches beyond the seat edge to add lying space, and the enclosed 35.43-by-23.62-by-23.62-inch design includes a seat-belt fixing structure.

An extended platform reaches beyond the rear seat edge, giving a large dog more floor area to lie down, stretch, or change position. Sintuff pairs that space with an enclosed riding area and front mesh, making this a backseat-focused option for owners seeking room beyond a conventional seat-sized crate.

The 35.43-by-23.62-inch base extends the usable area beyond the seat edge, which can help a dog shift position during longer rides. Its enclosed layout creates a defined place in the back seat and helps contain loose fur, according to the product description. Airy front mesh provides visibility, while side mesh panels include storage pockets for small travel items. The listed components also include a seat-belt fixing structure, relevant to securing the carrier in the car.

Skip it if you need a stated weight limit before choosing a carrier; PetSafe’s Happy Ride Collapsible Travel Dog Crate lists a 60-pound maximum recommendation.

Consider this for a large dog that needs extra backseat floor area to stretch or shift position, with an enclosure and mesh visibility. Its 35.43-inch length and unspecified maximum weight require careful consideration for your car and dog.

#5

5. JOYTUTUS 32-Inch Crate

• Material: Oxford
• Dog Breed Size: Large

Best for: Foldable SUV and trunk crate.

Why it ranks #5: Listed for car travel in sedans, SUVs, and trucks, it measures 32 by 23 by 23 inches and has securing straps, anti-skid pads, and a 50-pound recommendation.

A foldable structural frame makes the 32-inch JOYTUTUS crate easier to carry and pack for travel, while its listed fit includes mid-size SUVs, mid-size sedans, and truck trunks. Steel framing and securing straps make it a portable car option for dogs up to the stated 50-pound limit.

The 32-by-23-by-23-inch size is specified for several vehicle areas, including mid-size SUV and sedan use, helping shoppers assess whether it suits their intended spot. Straps secure the crate, and anti-skid pads help prevent sliding. A built-in safety leash adds an attachment point inside, while two-way zippers allow access from either direction. The foldable frame supports compact storage after a trip, though the maximum recommended weight is 50 pounds.

Skip it if you need a crate for a dog above 50 pounds; PETSFIT’s 36-inch Dog Travel Crate lists a 70-pound maximum recommendation.

This is a practical match for a dog within 50 pounds when a foldable crate, anti-skid base, and stated sedan or SUV use suit your travel routine. Check the 32-by-23-by-23-inch dimensions against the available vehicle area.

#6

6. HandinHandCreations Soft Crate

• Dimensions: 29"L x 22"W x 25"H
• Material: Flexible Fabric Or Plastic
• Dog Breed Size: Large

Best for: Flat-folding soft travel crate.

Why it ranks #6: Its 29-by-22-by-25-inch dimensions and multiple entry doors suit a large-animal travel carrier, and the soft crate folds flat with a storage bag.

Folding flat for compact storage is the main advantage of HandinHandCreations’ soft travel crate, with an included storage bag for packing it away. Its 29-by-22-by-25-inch dimensions are described as extra spacious for large animals, while multiple doors provide different entry and exit points.

The soft mesh is described as made to withstand pet wear and tear, and the multiple doors allow entry and exit from more than one opening. Those details can make access less restrictive during car trips. The crate’s 29-inch length and 22-inch width define its backseat footprint, while its flat-folding format and included bag support storage between journeys. The supplied facts do not state a maximum weight recommendation, so the listed size alone does not establish a weight limit.

Skip it if you need a stated maximum load before buying; Snagle Paw’s Portable Dog Crate lists a 20 kg maximum recommendation.

Consider this for a large animal that fits the listed 29-by-22-by-25-inch dimensions and for owners who value flat storage and multiple doors. The missing weight recommendation is an important boundary when assessing suitability.

#7

7. UNICITII Enclosed Car Carrier

• Dog Breed Size: Medium

Best for: Enclosed mesh-window backseat seat.

Why it ranks #7: This enclosed backseat carrier has mesh windows and instructions to fasten a safety belt and headrest strap, but its listed breed size is medium.

Mesh windows let a dog observe its surroundings while promoting airflow in UNICITII’s enclosed car carrier. Its installation instructions call for fastening the safety belt and hanging an adjustable strap around the headrest, giving owners two stated securing steps for backseat travel.

The enclosed format provides a defined area for a dog, and the product description says the roomy space allows dogs to stretch their legs. Mesh windows support airflow and visibility while traveling. For installation, the listed instructions specify fastening the safety belt and placing the adjustable strap around the headrest to promote stability. Machine-washable care is listed, though the product facts identify the breed size as medium and give no dimensions or maximum weight recommendation.

Skip it if you need confirmed dimensions and a maximum weight for a large dog; JOYTUTUS lists a 50-pound limit and 32-by-23-by-23-inch size.

This may suit a medium-sized dog when an enclosed, mesh-window carrier and machine-washable care meet your needs. Because the supplied specifications provide neither dimensions nor a weight limit, its fit for a large dog cannot be established.

#8 · Best Crash-Tested

8. Thule Allax Dog Crate L

• Dimensions: 27.2"L x 41.3"W x 27.6"H
• Material: Aluminum
• Dog Breed Size: Large

Best for: Crash-tested hard-crate choice.

Why it ranks #8: It is crash-tested from the front and rear and has a crumple zone, but its 41.3-inch width suggests checking vehicle placement carefully for backseat use.

Front and rear crash testing, including simulated rollover scenarios, is the defining feature of Thule’s Allax crate. Its stated 10-to-13-centimeter crumple zone is intended to absorb impact, making this a safety-focused option for owners who can accommodate a substantial, rigid car crate.

The adjustable depth, offered across five sizes, can help tailor the crate to both the vehicle and dog. A gas-dampened door mechanism holds the door open and helps prevent it from slamming shut, supporting smoother loading and unloading. Thule also describes the precision design as preventing rattling. At 27.2 by 41.3 by 27.6 inches and 26 kg, this is a sizeable, heavy unit; plan for its dimensions and weight when choosing and installing it.

Skip it if you need a lightweight crate that folds for trunk storage; Petsfit’s 36-inch travel crate is listed at 3.7 kg.

This suits owners prioritizing stated crash testing and adjustable depth for a car-based hard crate. Its 26 kg weight and 41.3-inch width make vehicle space and handling important considerations before selecting it.

9. GentleBliss XL Soft Crate

• Dimensions: 50"L x 21"W x 23"H
• Material: Metal, Polyester Blend
• Dog Breed Size: Medium, Small

Best for: Extra-long multi-pet crate.

Why it ranks #9: The 50-inch-long format is described for car travel and offers a thick cushion, but its listed breed sizes are small and medium rather than large.

At 50 inches long, GentleBliss’s soft-sided crate offers an unusually broad interior, with the product description stating room for two large dogs or several smaller pets. Its thickened cushion supports lounging, while the collapsible, foldable construction gives multi-pet households a way to pack it away between trips.

The 50-by-21.3-by-23.6-inch listed size provides substantially more length than a single-seat carrier, supporting the stated use for multiple pets that need room to stand, turn, or lie down. A thickened soft cushion adds a padded resting surface. Reinforced nylon Oxford and metal are listed materials, and the crate is marked breathable and collapsible. Its long footprint makes it a better match for a spacious vehicle area than a compact backseat setup.

Skip it if you need a compact crate for one seat with a specified restraint system; PetSafe’s Happy Ride uses one seat and lists a headrest strap and seatbelt slits.

This is for multi-pet households or owners seeking a long, cushioned travel enclosure and who have space for its 50-inch length. Measure the intended vehicle area carefully; the listed dimensions are far larger than a single-seat crate.

#10

10. Sherpa Forma Frame Carrier

• Dimensions: 22.83"L x 15.94"W x 15.94"H
• Material: Polyester
• Dog Breed Size: Large

Best for: Small-pet crash-tested carrier.

Why it ranks #10: Although it has vehicle-restraint straps and a foldable frame, its 22.83-by-15.94-by-15.94-inch size and 16-pound limit do not suit most large dogs.

Crash testing to standards for child restraint systems and straps for LATCH, ISOFIX, and other car-seat tether systems distinguish the Sherpa Forma Frame. However, its extra-large label does not make it a large-dog crate: the listed maximum weight is 16 pounds, so it suits only much smaller pets.

The tether-system straps offer several stated ways to connect the carrier in a vehicle. Claw-proof mesh windows provide ventilation, while escape-proof locking zippers help keep the carrier closed. A waterproof interior base and reversible, washable quilted mat address mess and cleaning. It also has a foldable frame for storage. But the 22.83-by-15.94-by-15.94-inch dimensions and 16-pound maximum recommendation sharply limit its relevance to a roundup focused on large dogs.

Skip it if you need a carrier for a large dog; Thule’s Allax Dog Crate L is listed for large dogs and has adjustable depth.

This is relevant only for a small pet whose weight stays within 16 pounds, despite the extra-large title, and for owners seeking tether-system installation. It is not a suitable large-dog backseat crate by its listed limit.
