Ice Collars are Fabulous! Large Swarovski Crystals make a big statement. Flash and shine! A real show stopper! These collars are 5/8" tall and range from 8inch to 14inch. Larger ones are available by special order. Made to last. Matching lead sold separately. To properly fit your dog for a collar, measure the inches around the dog's neck and make sure you can fit two fingers under the tape measure.
