Our Materials.
Every material has a provenance. Every supplier has a name. We choose our materials the way a good tailor chooses cloth — with patience, discernment, and an understanding that what touches your dog every day should be the best we can find.
01 — Italian Leather
Tanned for five centuries
in Tuscany.
In the valley of the Arno river, in the town of Santa Croce sull'Arno, Tuscan artisans have been transforming raw hides into leather using vegetable-tanning methods unchanged since the Renaissance. Oak bark, chestnut extract, and slow immersion pits — no chromium, no shortcuts.
The leather we use for The Milano Collar, The Riviera Leash, and The Capri Harness comes from tanneries certified by the Consorzio Vera Pelle Italiana Conciata al Vegetale — Italy's guarantee of authentic, traditional, chemical-light production. The consortium's shield mark is stamped on every hide we source.
Vegetable-tanned leather doesn't just last — it improves. The patina your dog's collar develops over months and years of wear is the leather absorbing the life lived in it. It's not a defect. It's the point.
Our Tanneries
02 — Organic Cotton
Grown clean.
Certified from seed to stitch.
The Porto Bandana starts not in a studio but in a field. We source organic cotton certified to the Global Organic Textile Standard (GOTS) — the gold standard for organic textiles, covering every step from raw fibre to finished cloth: farming practices, dyeing, weaving, and the workers who do it.
GOTS matters for dogs in particular. Bandanas sit close to your pet's skin, near their mouth, worked into the fur. Conventional cotton is one of the most pesticide-intensive crops in the world. Our cotton carries no residual agrochemicals, no azo dyes, no formaldehyde finishing.
We source through GOTS-certified mills in West Bengal and Maharashtra — suppliers who already provide fabric to brands like People Tree and Stella McCartney. We verify certificate numbers before every order.
What GOTS guarantees
- —Organic fibre verified at every stage of the supply chain
- —No toxic dyes, bleaches, or finishing agents
- —Minimum wage and safe working conditions throughout
- —Annual third-party audits — certificate numbers published
03 — Brass Hardware
Solid brass.
Because dogs deserve
the real thing.
The clasp on your dog's leash is the single point of contact between your hand and your dog on every walk. We use solid brass — not brass-plated zinc, not powder-coated steel, not die-cast alloy. Solid. Brass.
The distinction matters. Zinc die-cast hardware corrodes within months in salt air, rain, and the general chemistry of a dog's life. The plating flakes. The gate spring weakens. Solid brass develops a natural patina that only deepens the quality of the piece — the same quality signal that defines fine watchmaking and heritage luggage.
Every D-ring, swivel snap, and center-bar buckle is specified solid brass. We include this requirement on every purchase order and verify it on every sample. The weight you feel when you hold a Collio piece is not coincidental.

04 — Our Standards
The way things should be made.
Small-Batch Production
We make in limited quantities — enough to maintain quality, not enough to cut corners. Each run is reviewed before the next begins. We would rather sell out than compromise.
Ethical Manufacturing
Every workshop we use is evaluated for labor practices, not just cost. We do not source from factories we cannot visit. Minimum wage is a floor, not a ceiling.
Artisan Assembly
Our pieces are assembled by hand by leatherworkers who have been making fine goods for years. The stitch spacing, edge finish, and tension on every buckle reflects that experience.
Full Transparency
We name our tanneries. We publish certification numbers. If you want to know exactly who made your dog's collar, we will tell you — down to the tannery address in Santa Croce sull'Arno.

Our Promise
“We publish every supplier's name, every certification number. That transparency isn't a marketing line. It's our minimum standard.”
The Origin
The leather in your dog's collar was tanned in Tuscany using methods unchanged for 500 years — oak bark, slow tannery pits, and artisan hands.
The Making
Each piece is assembled by hand by leatherworkers who make goods as if they will be inherited. Because some of them will be.
The Promise
If you want to know who made your dog's collar and where the leather came from, we will tell you — right down to the tannery address.
