Pick your winter

Both now come with a harness hole. The only question is what kind of cold your dog walks in.

The big idea

Now it's your call

Same Chilly Dogs warmth and fit. Two ways to wear it — and both the Great White North™ and the Northern Blazer now come either way. Because every dog, and every dog parent, prioritizes something a little different.

Option A · New

With a harness hole

An opening on the back lets your dog's harness clip come up through the coat — and clip on the leash.

  • The leash clips on right through the coat
  • Wear the harness under the coat, or over top
  • Works with back- and shoulder-attaching harnesses
Option B · Classic

Without a harness hole

The original clean-backed coat — a smooth, fully-covered shell for pups who wear a collar, or gear up over top. Still available on both coats while supplies last.

  • Maximum, uninterrupted coverage
  • Sleek, classic silhouette
  • Great for collar-and-leash walkers

The point: there's no wrong answer. Now you get to choose the one that fits your dog's routine.

How it works

How the harness hole works

A HOLE new way to walk: harness on, coat over, clip through, go.

Close-up of a leash clipped to a harness coming up through the harness hole on the coatClip-through opening
  1. 1

    Harness on, coat over

    Pop your dog's everyday harness on first, then slip the coat over top — it works the same on both the Great White North™ and the Northern Blazer.

  2. 2

    Clip comes through

    The harness's back or shoulder attachment point lines up with the opening and comes up through the coat.

  3. 3

    Leash up and go

    Clip the leash straight to it. The overlap around the opening helps keep snow and water from sneaking in — and it doesn't change how warm the coat is.

Pairs perfectly with the Perfect Fit HarnessMade to sit comfortably under the coat and line up with the opening — not sure which harness? Start here.

The kit · Side by side

Which coat is your dog's?

Both share the same warm Canadian polar fleece lining and the same harness hole. The difference is the shell — and the weather it's built for.

What the Pack says

Real reviews of the Great White North™ from dog parents across Canada.

"Best coat ever! It keeps him warm and fully covered with full mobility. I love the velcro along the sides so the strap doesn't move. Very easy to put on and take off."

Leslie N. · Verified review · Canada

"Excellent jacket, easy to put on and off. The fleece keeps dogs cosy warm."

Your questions

Harness hole, answered

Does the coat have a harness built in?
No — it's a coat with a harness hole. Your dog wears their own harness, and the attachment point comes up through the opening on the back so you can clip the leash on.
What harnesses does it work with?
Back-attaching harnesses (or a step-in with the D-ring at the shoulders). The hole sits near the shoulder blades, so the clip comes up through it and the leash attaches right there.
Not sure which harness to pair it with?
Try our Perfect Fit Harness — made to sit comfortably under the coat and line up with the opening.
Can my dog still wear a harness over top?
Absolutely. That's the whole idea of choice — clip through the hole, or wear a harness over the coat. Whatever works for your walks.
Does the harness hole make the coat colder?
No. It doesn't change the overall warmth — it's just a small opening on the back, and the overlap around it helps keep too much snow or water from getting in.
Why make coats with and without a harness hole?
Choice. Every dog lover prioritizes something a little different — so now you can pick the coat that fits your dog, no matter what they need. Both the Great White North™ and the Northern Blazer come either way.
Great White North™ or Northern Blazer — which one?
Go Great White North™ — our classic winter coat — for snowy, cold days. It's our warmest coat, built for snow, not rain. Go Northern Blazer if your winters are wet and changeable: same warm fleece lining, with a moisture-shedding shell and nylon neck coverage for slush and wet snow. Either way, the harness hole works exactly the same.
How do I get the right size?
Over 30 sizes across three cuts (Standard, Long & Lean, Broad & Burly). And with our Perfect Fit Promise, we review every order and reach out if your measurements suggest a better fit. Your path to the perfect fit starts here →
