BioThane® Adjustable Martingale Collar

Our popular BioThane® collars have been upgraded and are now available with a buckle! You'll also find two different sizes with varying widths (25 mm and 19 mm).

Our Biothane® Adjustable Collar can be adjusted to any length, ensuring not only a perfect fit. Thanks to its high-quality clasp, it can be put on in a flash and allows even dogs with a head circumference significantly larger than their neck circumference to wear a slip chain collar. The material is not only lightweight and comfortable to wear, but also highly stain-resistant: the waterproof BioThane® can be easily cleaned with water and, unlike leather or nylon, does not retain odors. The SPRENGER pull-through chain, made of high-quality stainless steel, provides security and prevents the dog from wriggling out, while allowing the collar to sit loosely around the neck. The high-quality design is rounded off by a subtly embossed SPRENGER logo. With 5 bold colors in 2 sizes, you’re sure to find your new favorite collar.

So our Biothane products are clean again in a flash

Our Biothane products are super easy to clean. The waterproof material can be easily wiped clean and is clean again in no time. This keeps the Biothane in top form for the dog's entire life.

Biothane

Our Biothane products are made from the highest quality materials in the USA. They are waterproof and odorless and have a significantly higher breaking strength than leather or nylon, which makes them suitable for heavy and strong dog breeds.
