The Outback is usually the first Subaru people recommend for dogs, and the reason isn’t marketing, it’s wagon geometry. A long rear cargo floor and a low liftover height do more for a dog’s comfort than any accessory you can buy.
This guide skips the generic “works great for every dog” framing and focuses on what’s actually different about the Outback specifically: where its cargo shape helps, where it doesn’t, and how that compares honestly to the Forester and Crosstrek.
Why the Outback’s Shape Actually Matters
Cargo volume numbers get thrown around a lot, but the number that actually affects a dog’s comfort is floor length, not cubic feet. The Outback’s long rear overhang means a medium or large dog can lie fully stretched out rather than curled up, which starts to matter once a drive passes the one-hour mark.
The low liftover height is the other real advantage, and it’s not just a nice-to-have for a healthy adult dog. It makes a genuine difference for older dogs, puppies, or a dog recovering from surgery who shouldn’t be jumping to get in.
The wide rear hatch opening matters more than it sounds too. Loading a crate, or coaxing a nervous dog in, is noticeably easier with more clearance than a narrower hatch gives you.
Cargo Area vs. Back Seat in an Outback
For anything bigger than a small dog, the cargo area is the better call, and specifically because the Outback’s floor is long enough that a barrier doesn’t turn into a cramped box the way it can in a smaller vehicle.
The back seat still makes sense for a small dog riding alongside a passenger, or on a day when the cargo area is already full of trip gear.
What Actually Changes By Dog Size
- Small dogs: either location works fine, and you won’t notice much benefit from the Outback’s extra length.
- Medium dogs: the cargo area handles it easily, with enough floor space left for a duffel bag or two.
- Large and giant breeds: this is where the Outback separates itself from the Crosstrek and edges out the Forester. The extra floor length is the difference between a large dog resettling comfortably on a three-hour drive and one stuck in the same position the whole way.
- Two dogs: doable, but expect to leave most other cargo behind unless you’re supplementing with a hitch carrier or roof box.
Barrier or Crate?
A barrier is the better default for most Outback owners. It’s lighter, faster to pull out for an unrelated grocery run, and the Outback’s wide opening means a full-width barrier doesn’t box the dog in the way it might elsewhere.
A crate makes more sense specifically if your dog is already crate-trained or gets anxious in open space. A barrier doesn’t reduce anxiety, it just contains movement. If you go this route, measure the crate against your actual cargo floor length before buying. A large crate and a large dog together can use the entire floor, leaving nowhere for anything else.
Outback vs. Forester vs. Crosstrek, Honestly
If you need a dog to stretch out fully on long drives, or you’re regularly carrying a large dog plus gear, the Outback’s length wins. The Forester counters with more headroom and an easier stand-and-turn-around motion. The Crosstrek is the right call only if you have one small-to-medium dog and don’t need much cargo room alongside it.
FAQ
Does the low cargo floor actually matter, or is it a spec-sheet thing?
It matters most for dogs that shouldn’t jump: older dogs, puppies, post-surgery recovery. For a healthy adult dog it’s a comfort improvement, not a necessity.
Barrier or crate for a nervous dog?
Crate, if your dog is already used to one. A barrier keeps a dog contained but doesn’t do anything to reduce anxiety the way an enclosed space can.
Can I fit a large dog and a week’s worth of luggage?
It’s tight but workable if you switch from hard coolers and bins to soft duffel bags, which compress around the dog’s space instead of taking up a fixed rectangular footprint.
Is the Outback overkill if I only have a small dog?
Not overkill, but you won’t see much benefit over a Forester or Crosstrek. The Outback’s advantages show up specifically with larger dogs and longer drives.
What We’d Actually Buy
A cargo liner sized to the Outback’s full floor length protects the interior without bunching up. A barrier is the better first purchase over a crate for most owners, for the reasons above. If your dog is already crate-trained, size the crate to your specific model year’s cargo floor length before ordering. That’s the one measurement that actually determines whether it’ll work here.
