I have a coach dog collar that I received in a box of items I won at an auction. It does not look like it has been worn. The size says: Large 18"-20". Sale for $5.00 plus actual shipping and a 3% charge if paying with paypal to cover their fees. If interested send me a pm. Thank You. The next item is a muzzle for I would say a very small dog. I actually have two of these and both are new with the tag attached. The number 3 is on the collar, don't know if this refers to a size or not. I would say these would fit a chihuahua or other small breed dog. Price $5.00 plus actual shipping and 3% fee if using paypal. Send me a msg. Thank You I will list these on craigslist this evening if noone shows any interest.
