NorthPaw CozyCore
They count on you to
keep them comfortable.
Chilly mornings, cold sidewalks, and quick trips outside don’t have to mean leaving your dog without an extra layer of warmth. CozyCore surrounds them with a thermal layer and soft, plush fleece, while the built-in harness makes it easy to clip on the leash and head out together.
- Fleece-lined coat and built-in harness in one
- Made for everyday walks and potty breaks
- Never leave them cold again
- 100% waterproof
The Problem
You can feel the cold. They feel it even more.
When temperatures drop, don’t assume your dog’s fur is enough. Dogs with thin coats, especially smaller breeds, can struggle to stay warm in conditions that thick-coated breeds tolerate much better. Shivering, tucked tails, lifted paws, and reluctance to walk can all signal that your dog isn’t comfortable. A soft, warm layer makes a real difference.
- Shivering or trembling on chilly walks
- Lifting paws or hesitating at the door
- Rushing potty breaks to head back inside
- Short-coated and lean dogs feel it first
Why Most Coats Fall Short
You tried a coat. Then a harness over it.
A thin shell barely adds warmth. A bulky coat can fight the harness. Layering a separate harness over or under a coat means extra steps, awkward fit, and fiddling with straps before you’ve even left the house — two pieces and a routine that never quite works together.
- Too thin: a light shell adds little warmth
- Too bulky: puffy coats can fight the harness
- Separate harness: extra layering and awkward fit
The Fix
Warmth they need with the convenience you’ve been missing.
CozyCore brings warmth and convenience together in one coat. The outer shell, insulating thermal layer, and plush fleece lining provide an extra layer of warmth when temperatures drop. With the harness built right in, you can skip the extra layers and adjustments — just get your dog dressed, clip on the leash, and head outside. More warmth for your dog. Less hassle for you.
- Quilted outer shell with a finished look
- Plush fleece lining, soft against the coat
- Built-in harness webbing, buckles, and rings
- One layer on — then clip and go

No more puppy pads in January.
Every winter was the same — she’d get to the door, feel the cold, and turn right back around. We ended up using puppy pads for months because she just refused to go out. Tried a thin sweater but it didn’t do much. The first morning in the CozyCore she walked right outside and did her business like it was nothing. Haven’t touched a puppy pad since.
She used to shiver the entire walk.
My girl would start shaking before we even got to the end of the driveway. I felt terrible making her walk like that, so we’d rush through it and head back inside. Now she’s warm enough to actually enjoy being out. No shivering, no pulling toward the house — she even wants to keep going. I wish I’d found this sooner.
One layer, leash clips right on. Done.
I used to put a coat on him, then try to wrestle the harness over it. Half the time the coat bunched up or the harness wouldn’t clip right. With the CozyCore it’s one piece — coat on, buckle, clip the leash, and we’re out the door. He’s warmer and I’m not fighting with two layers every morning.
Straight Answers
The things people ask us before they buy.
These are the real questions that come in — mostly from dog owners who have tried a coat or a harness but never both in one piece. If yours isn’t here, reach out and a real person will answer it.
Contact UsYes. CozyCore is three layers — a quilted outer shell, a thermal insulating layer, and a plush fleece lining. It’s built for cold morning walks, not just cool autumn days. Dogs that used to shiver through the whole block stay comfortable from door to door.
The harness uses reinforced webbing stitched through all three layers, with metal D-rings and side-release buckles. It’s built for everyday leash walking, not decorative. Clip the leash to the back ring and the pull distributes across the chest, not the neck.
Measure around the widest part of your dog’s chest with a soft tape measure, then check the size chart on this page. We carry XS through 4XL to cover a wide range of builds. If you’re between sizes, go up — a slightly roomy coat is more comfortable than one that’s too snug.
Yes. Machine wash cold on a gentle cycle and lay flat to dry. The fleece stays soft wash after wash, and the outer shell holds its shape. Skip the dryer — heat can weaken the bonding between layers over time.
It depends on the fur. Dogs with thin, single-layer coats — like Greyhounds, Chihuahuas, Frenchies, and Pit Bulls — lose body heat fast in cold weather. Even medium-coated dogs can benefit on below-freezing days. If your dog shivers, hesitates at the door, or rushes potty breaks to get back inside, a warm layer helps.
Our 30-day guarantee covers fit. If the size isn’t right, we’ll send a replacement in the correct size or refund you in full — no hoops, no restocking fees. Your dog should be comfortable, and you shouldn’t have to guess whether you’re stuck with it.
