NO NOISY HANGING ID TAGS! Available in various colors and sizes. Mix and match colors. We offer 5 collar choices and 8 tag choices. PLEASE NOTE that we will correctly match the collar size with the suitable tag size. Collar lengths 6-8 inches are 3/8-inch-wide, 10-12 inches are 5/8-inch-wide, 14-16 inches are 3/4-inch-wide, and 18-24 inches are 1 inch wide. COLLAR SIZES are determined by the measurement from the middle of the metal buckle to the first hole - which is the smallest size the collar will adjust to. To determine the correct size, use a soft tape measure or piece of string and wrap it snugly around the base of your dog's neck - snug enough so that you cannot fit any fingers under the measuring tape. Round measurement down to the nearest even number. For instance, if your dog's neck measures 17" you would order a 16" collar. TO ORDER click CUSTOMIZE NOW.
