For Cuban collars with a buckle, wrap a soft measuring tape around the middle of your dog's neck with two fingers under the tape. Record this measurement in inches. Choose that size if available, or round up to the next available even size. Do not add another 1-2 inches after measuring with two fingers. Check the sizes available on the product page; for other products, follow their own sizing guidance. Read the sizing guide.
