BioThane® Adjustable Martingale Collar with Buckle

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.
