Collection: Winter Dog Coats for Big Dogs

Winter dog coats for big dogs: coats for large and giant breeds that many size charts skip, in back lengths 25 to 31 inches, with room through the chest.

Two coats, because warm and waterproof are two different specs: a double-sided fleece for cold fall and winter days, and a fleece-lined, full-body snowsuit rated 16,000 to 20,000mm waterproof for snow, slush and freezing rain. Both use our Full-Stride Cut: the shoulder seam runs around the shoulder blade, not across it. Sizes are back length in inches: the back length picks the size (right on the line, take the smaller one), and if the chest is over that size's limit, go one up.

Reviews

Big, deep-chested, and it fits.

“He has the wide chest of a bully and really hates extreme temps. We have tried several different suits that were too tight in the chest, didn’t have 4 leg coverage or were not very warm.”
★★★★★Dawn R. · Snow Warrior Suit
“I have an 80 lb doberman who has a deep chest and clothes never fit him right. This jacket fits great!”

FAQ

Winter coat questions, answered.

Which coat should I pick?

The Cozy Hugger is a double-sided fleece for cold fall and winter days, light snow and drizzle included. The Snow Warrior is for snow, slush, sleet, freezing rain and wind: a microfleece lining inside a waterproof, windproof shell, with full leg coverage.

Is the Cozy Hugger waterproof?

It isn't waterproof, but light snow and a passing drizzle brush right off, and plenty of our customers' dogs play in the snow in it. On long walks in steady rain, heavy wet snow or slush it soaks through over time, so the Puddle Jumper Raincoat or the Snow Warrior Suit is the better pick. Towel off and dry the jacket after a snowy walk.

Does my double-coated dog need a winter coat?

Often not. Huskies, malamutes and other thick double coats handle cold well on their own. Thin-coated, short-haired, older and very lean dogs feel it more. Our guide on which big dogs need a winter coat walks through it breed by breed.

How cold is too cold for a walk?

It depends on the dog: coat, size, age, and whether it's wet. On very cold days, keep walks shorter, coat or no coat. Our guide How cold is too cold for dogs? walks through the signs to watch for.

How do I pick the size?

Measure the back length and the chest. The back length picks the size (right on the line, take the smaller one), and if the chest is over that size's limit, go one up. Both coats have a tail drawcord that shortens the back about 2–3″. The size guide works it out from both numbers.

What if it doesn't fit?

Try the drawcords first: most coats that feel a bit big fit once they're snugged up. Still not right? Exchanges are free, and returns are easy. Message us with a side photo and we'll tell you which size to swap to. Final sale items can't be returned or exchanged.
