READ: Be sure to measure for custom goods. EASY SIZE INSTRUCTIONS: To find the perfect size kindly measure your dog's neck and chest BEFORE YOU BUY and ensure these two measurements fall within the numbers listed in the size chart. Ensure the head is at least the same size as the neck so that the neck opening can slide over the head. If your measurements fall at the end, go up one. You may message the Seller for help before you buy. PRODUCT INFO: Buy a handmade, vest style, personalized Blue Denim SOFT DOG HARNESS gift, custom embroidered dog harness with a FREE PET NAME.
