The makers

Meet the makers

We’re Katie and Dan, a husband-and-wife team from South Wales. Between a drawer, a garage and the back of the car we had collected more leads and collars than we could count, and still not one of them was quite right. So we started making our own.

Every lead and collar is cut, finished and checked by hand in Newport – made to order, in small batches, never pulled off a shelf. We use BioThane rather than leather or webbing because it is fully waterproof, incredibly strong and wipes clean after the worst walk of the week. When you order something, we make it and we answer your email.

How it works

Nothing is made until you order it

Which is why it takes a few days, and why it fits.

  1. One

    You choose

    Measure your dog, pick a size, then choose your colours – for the collar, the lead, or both. It's made for your dog, not picked off a shelf.

  2. Two

    We make it

    Once you order, we cut the BioThane for your dog's size and finish it by hand. Every rivet pressed home, metal fixings set and checked.

  3. Three

    It arrives

    Made in 3–5 working days, then 3–5 working days in the post. UK delivery is £5 on every order.

Before you ask

The three we get asked most

How do I measure my dog for a collar?

Measure right around the base of your dog's neck – where the collar will actually sit, low down near the shoulders – keeping two fingers flat under the tape as you go. That measurement tells you which of our five sizes, XS to XL, to order. Don't measure just behind the ears, as the neck narrows there and you'll get a size that rides up under the jaw. If you haven't got a tape measure, a piece of string laid against a ruler works just as well.

How to measure your dog for a collar

Do you deliver across the UK?

Yes – we deliver anywhere in the United Kingdom for a flat £5, with no minimum spend and no surcharge for a heavier parcel. Delivery takes 3–5 working days once your order has been made. We don't post outside the UK at the moment.

Shipping & delivery

Do your products come with a warranty?

Yes – every product carries a one-year warranty from the date of purchase, covering repairs for general wear and tear. You'll need proof of purchase to claim, so please keep the invoice that comes with your order: it's your warranty document. If something needs repairing within the year, you pay the postage to send it to us and we repair it and post it back to you free of charge, like for like. This warranty is in addition to your legal rights, which it doesn't affect.
