Dog clothes aren’t just for the little guys. Just like small breeds, large dogs can need an extra layer for comfort, protection, and warmth when the weather gets chilly. And we’ve known more than a few who were happy to dress up just because.
But finding the optimal extra-large outfit for a big dog can be tricky. Not only do giant breeds need larger sizes, but clothes for large dogs also need durable construction with double stitching and strong closures to withstand a large dog’s wear-and-tear.
That’s why we’ve rounded up some of our favorite clothes for large dogs, from practical rain jackets and coats to fashion-forward costumes—so your canine is covered for every occasion.
One tip: Because sizes can vary wildly from manufacturer to manufacturer, we recommend measuring your large dog and prioritizing a product’s sizing chart over weight ranges or traditional “small,” “medium,” and “large” designations.
Best Big Sweater: Canada Pooch Soho Dog Sweater
Sweaters are usually the least durable when it comes to dog clothes—but they’re hard to beat for comfort when you’re trying to keep a big dog warm indoors. This cozy and relatively sturdy chenille dog sweater is made with machine-washable yarn, and if you want to leave it on for potty breaks, it even has a leash opening on the back so your pet can wear it safely with a leash or back-clip harness attached.
No sleeves and material with lots of give make this a pretty easy sell for a chilly dog, though it’s worth noting that your pup will need to be comfortable with a garment that goes on over the head to wear this happily.
Key Features:
- Available in a range of sizes to fit up to a 30″ to 35″ girth
- Pull-on design
- Made with space dye yarn
Best Large Raincoat: HugeHounds Rain Rover Extra Large Raincoat
Designed for extra-large and plus-size breeds, including St. Bernards, Huskies, and Mastiffs, this raincoat from mom and pop business HugeHounds is up for the challenge of keeping a big pup dry on rainy day walks. It’s made with a protective half-hood to keep water out of dogs’ ears without obscuring their vision and is constructed with highly breathable waterproof material.
Two Velcro attachment points mean no over-the-head fitting and no paw lifting for leg holes. The coat also sports longer, larger straps to maximize adjustability.
Key Features:
- One-size only, for dogs over 85+ pounds with up to a 48″ girth and 46″ belly
- Opening on the back allows for leash and harness access
- Folds up to fit in accompanying travel bag
Best Large Dog Jacket: PetRageous Designs Calgary Insulated Dog Jacket
If you live in a climate with harsh winters, you know even the fluffiest and largest pups need an extra layer sometimes. This popular insulated dog jacket from PetRageous offers good waterproof coverage in a medium-to-heavy weight. We especially like the two-way zipper on the back that allows for easy leash attachment to a collar or harness.
Note that the neck isn’t adjustable, so big breeds with big heads (looking at you, Mastiffs) may want to prioritize more flexible designs.
Key Features:
- Available in sizes XS to XX-Large
- Adjustable Velcro belt on stomach for a custom fit
- Full chest coverage and reflective strips to keep your pup safe

This snowsuit offers maximum coverage to keep a pup warm and protected from the cold.

Whether it’s a super windy day or your pup is ready to make some snow angels, this suit is up for adventure.
We especially like it for Doodle dogs with curly fur (no snow crusting here) and slender dogs who need the insulation (that’s you, Greyhounds and Whippets).
Key Features:
- Available in sizes 8 to 28 to fit up to a 27″ to 29″ back
- Thermal foil lining helps retain body heat
- Adjustable neck to keep your dog comfortable
