About sizing (Sizing Guide in photo gallery): In order to calculate your pooch’s size, you’ll need to measure your dog’s length from the base of the neck to the base of their tail, which serves as the primary measurement in our clothing. The neck, as well as 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.
