Want an extra pop of color?  Our Catalina Biothane Collars come with a colored strap-keeper - match your collar, or mix it up!   BioThane® Beta is a coated webbing that is water-proof, stink-proof, super durable, stronger and lighter than leather. Made in the USA, BioThane® Beta has a soft, easy-to-grip feel and is very pliable even in the coldest weather. Easy to clean with soap and water and antimicrobial, so no need to worry about even the dirtiest outdoor activities with your dog.
