Biothane: Width and Fastener for Your Collar

When ordering a handmade Biothane collar from adorit.be you have various options regarding Biothane width and fastener. Alongside practical aspects, taste always counts here too.

Biothane width 19 mm, 25 mm — and the Bicolor models

We make plain Biothane collars in two widths — plus the two-layer Bicolor models.

In the shop you find every width as a collar without and with print. If you cannot find your preferred variant, feel free to contact us by mail: [email protected]

Pin buckle or Clic fastener?

As a rule, all fittings and rivets are made of brass. The Clic fasteners are made of very sturdy plastic with a safety button. Do you have other wishes? Mail us at [email protected] and we will look into the possibilities with you.

For puppies and young dogs?Yes — state age and breed in the note of your order, then I will make the holes so it can "grow along".Yes, but since it is not adjustable, it cannot "grow along", so on dogs that are still growing it will not fit forever.
Measure accurately?Important, so that the perfect hole sits in the middle.Important, since it is not adjustable.

Which width suits my dog?

The right width is a matter of taste; both widths are strong. Customers order wide collars for small dogs from us — and vice versa.

Torn between 19 and 25 mm? Write or mail us — we will gladly think along with you ([email protected]) or via the contact page. With a neck circumference of less than 35 cm we recommend the small buckle.

Measure first, then choose

Always measure the neck circumference carefully with a measuring tape before ordering — how to do that exactly is explained step by step in our measuring guide. With the Clic fastener correct measuring is especially important: the size is fixed and cannot be adjusted afterwards.

Frequently asked questions (FAQ)

Can I still adjust the size later?

With the pin buckle yes: the stated neck circumference sits in the middle of the adjustment range, and you can adjust 2–4 cm in both directions — depending on the model. That is not possible with the Clic fastener; its size is fixed.

Is the Clic fastener also suitable for puppies and young dogs?

Possible, but not optimal. The Clic fastener is better for adult dogs. Because the size is fixed, the Clic collar does not grow along with a young dog.

Which width for a neck circumference under 35 cm?

With a neck circumference of less than 35 cm we recommend a collar with a small buckle. With a larger neck circumference both widths are possible.

What does 19/25 or 25/50 mm mean on the Bicolor collar?

Bicolor collars are made in two layers: the narrower upper layer (19 or 25 mm) lies on a wider lower layer (25 or 50 mm). On the 25/50 mm model the lower layer is always orange; you choose the upper colour yourself — the print is printed on the upper layer.
