About sizing (Sizing Guide in photo gallery) To calculate your puppy’s size, you’ll need to measure your dog’s length from the base of its neck to the base of its tail, which is the primary measurement in our clothing. The neck and the breed guide provided in the sizing chart will help ensure you select the correct size for your dog in the particular product style you desire. * Shadings and variations are common in handmade products.
