How to properly determine your dog’s chest size: Use a cloth measuring tape from behind the front legs to around the deepest point of your dog’s chest to determine a perfect fit. If you do not have a tape measure, you may use this method with a piece of string and lay it next to a ruler or yardstick to get an idea of his or her chest size.If in doubt or in between sizes, we recommend choosing the next size up.
