This is the Bandana Red Elements Dog Collar - Size Medium - 3/4 inch wide and fits neck sizes 13.5 to 17 inches with the style and quality you come to expect out of Yellow Dog Design, but now with the added durability of a urethane coating. The Elements line of collars has been specifically designed to be resistant to odor, dirt, salt water, fresh water, rough outdoor play and work, tearing, chewing, and just about anything else your dog can do to it. SIZING: This dog collar utilizes a BUCKLE STYLE closure. Sizing is given as the Size # (total length of the collar) and the Wearable Length (where the sizing holes are). REMEMBER, these collars can be cut and additional holes added with no special melting or burning required like regular nylon. If you are shopping for designer, affordable dog and pet accessories, then look no further. These durable, guaranteed to last dog accessories have no rough edges, no threads to fray or break, no problem going in the wash, and no stress getting them on or off your dogs.
