A custom fit for your beloved pet! Our BioThane® Adjustable Collar, 25mm wide, is infinitely adjustable, ensuring not only an optimal fit but also allowing dogs with a significantly larger head than neck circumference to wear a slip-chain collar comfortably. The collar's material is not only lightweight and comfortable but also exceptionally dirt-resistant: the water-resistant BioThane® can be easily cleaned with water and, unlike leather or nylon, doesn't develop an odor. The SPRENGER slip chain, made of high-quality, rust-free stainless steel, provides security and prevents the dog from wriggling out, while allowing the collar to sit loosely on the neck. Our collar is available in a variety of colors, so there's something to suit every taste. A discreetly embossed SPRENGER logo completes the high-quality design.
