It all started with one dog.
This is the long version. Why we built it, who we built it for, and why June is on every spec sheet.

She refused to stay home.
Every morning, June would watch the running shoes go on. Then she'd plant herself at the door. The polite stare. The one that meant: I am coming with you.
We tried. With every leash on the shelf. They all did the same thing: wrist-wrap, jerk, lose your stride. After three months of bruised forearms and ruined splits, we gave up on the market and started sketching.
“Either we figure this out, or we leave her behind. Both options were unacceptable.”

One prototype. Then sixty.
Bungee climbing webbing salvaged from a retired rope. A repurposed running-vest waist belt. A harness made from car seatbelt fabric and 8mm closed-cell foam. The first one was ugly. It worked.
We sent versions to seven canicrossers, two trail runners, a vet, and a long-distance hiker in the Pyrenees. They sent back notes — sometimes diagrams. The leash got a 4ft–6ft adjustable section. The harness gained the Y-front geometry.
By version 60-something, we had something that didn't get returned.

Now we're everywhere.
Five hundred and counting. The Kit is on a vizsla in Boulder. A border collie in Portland. A kelpie running beach laps in Melbourne. A lab in Manchester. A spaniel-cross on a UK fell.
We still test every batch against June first. If she doesn't run smooth in it, the batch doesn't ship. That's the standard.
The brand is built on her. The product is named for her morning routine. The reviews keep coming back the same: “My dog and I finally run together.”
