Our Thin BioThane Adjustable Collars are made from scent-proof, durable, and waterproof material. We offer them in two martingale styles or a regular snap collar. This style slips over the dog's head so sizing is important! We also offer the same type with a buckle for easy on and off. Lots of fun colors available! The material and product is made in the USA. Check our other products for matching leashes! Questions on sizing? For these collars, please measure at line #1 on the dog silhouette. For more info visit our sizing page!
