Measure your corgi in 30 seconds
Stand him up. On a flat floor, treats in your hand, four paws down.
Chest first. Wrap a soft tape (or a piece of string, then lay it on a ruler) around the widest part of the ribcage, right behind the front legs. Snug, not tight, flat against the coat. Write the number.
Then the neck. Low on the neck, where a harness sits, not up at the collar line. Write the number. If his neck number falls in a bigger size than his chest, take the bigger size and take the chest strap in.
Chest decides the size. Weight is only a starting point. Between two sizes? Pick the larger one and take the straps in.

Sound familiar?
You know this walk.
The harness comes out and he goes quiet. Or he's under the sofa before you've picked it up.
You stop every few minutes to straighten it, because it has slid around to one side again.
Last month you found a patch of rubbed hair behind his front leg, and you felt awful.
At the curb you hold the leash tight and hold your breath, because he is one step backward from being out of it.
And this is harness number four. Each one fit a different dog.
In the reviews of one best-selling dog-harness store, 40 of the 71 reviews at 4 stars or below were about size.
None of this is you doing it wrong. A corgi is a long back, a deep chest and short legs, and almost every harness is cut for a dog that is none of those.
Harnesses are sized by weight. A corgi isn't built by weight.
A corgi has the chest of a dog twice his weight, the legs of a dog half his weight, and a back like a bridge. A harness sized by weight is wrong in three places at once.

The neck loop is loose.
A weight-sized harness is made for a narrower chest, so the neck opening is cut wide. He backs out at the curb.
Ours: neck and chest adjust apart, so the neck loop sits snug while the chest has room.

The strap sits in his armpits.
Short front legs, strap too far forward: rubbed hair, a dog who hides when it comes out.
Ours: the Y-front opens clear of the shoulders and the strap sits back behind the elbow.

The chest panel is too short.
It twists, rides up, and the pull lands on his neck and along his long back.
Ours: a deep padded chest plate carries the pull on the breastbone, the strongest part of his body.
Illustrations.
That's why owners buy four harnesses. This is one harness, cut around all three.
What your mornings look like with a harness that fits.

Hold the leash loose at the curb.
The neck loop is snug and the chest has room, so there is nothing to back out of.

See him come to you when the harness comes out.
No hiding behind the sofa. A harness that doesn't rub is one he lets you put on.

Lift it off at night and find nothing red.
The strap sits behind the elbow, not in the armpit.

Clip on one-handed in the dark parking lot.
No step-in puzzle. Clip, adjust, go.
This is for you if
- His harness slides, twists or rubs.
- He backs out of it, or you worry he will.
- You size by weight and it never fits right.
- You are on your second or third harness already.
This is not for you if
- You want one harness to fit every dog in the house.
- You would skip the two-finger fit check before the first walk.
- Your dog is not a corgi. This one is cut for the corgi build.
- You would rather guess the size than measure.
Fit it in three steps.

1Put it on
Get the neck loop in place and let the Y-front sit on his chest, clear of the front legs.

2Fasten and adjust
Close the belly buckle and set the neck and chest straps one at a time.

3Check with two fingers
Two fingers flat under the chest strap and under the neck strap. Snug, not tight.
Your questions, answered plainly.
Which size should I get?
Measure his chest, right behind the front legs. Chest decides the size; weight is only a starting point. Find his chest number in the size chart and pick that size. Still unsure? Message us his chest number and two photos and we'll tell you the size.
He's between two sizes. Which one?
Pick the larger one and take the straps in.
Can he back out of it?
Not when it's fitted. The neck and the chest adjust separately, so the neck loop sits snug on his neck while the chest fits his chest. Do the two-finger check (two fingers flat under the chest strap and under the neck strap) before the first walk.
Will it rub under his front legs?
The Y-front opens clear of the shoulders, so there is nothing pressing into his armpits.
Will it twist or slide to one side?
The deep chest plate keeps it centered, and the neck and chest straps pull it into place.
Which ring do I clip the leash to?
Back ring for easy walks. Front chest ring when he pulls: it turns him back toward you instead of letting him lean into the strap.
I have arthritis in my hands. Is it easy to put on?
We built it to be simple: three steps, no puzzle. See "Fit it in three steps" above, and message us if you'd like a hand with the first fitting.
Is it good for his back and neck?
That is what it is built for. The pull lands on the breastbone, never on the neck or along the spine, which is why it suits long-backed dogs.
How long does delivery take?
You get a tracking number by email when your order ships. Delivery times are shown at checkout.
Will it fit my Cardigan, my corgi mix, or my puppy?
Cardigans and bigger-boned corgis: measure the chest and find that number in the size chart. Mixes: the chest number decides, not the breed. Puppies: size for his chest today.
How do I wash it?
Hand wash with mild soap and warm water, then air dry.
Will the buckles and rings last?
We built it for daily walks. If a part ever fails, message us and we'll make it right.

Your corgi has been through four harnesses. Let this be the one that fits.
Measure his chest, pick the size on the chart, and walk him without fixing a strap.
