If you're unsure of your dog's size, use a soft measuring tape and wrap it around your dog's neck and the widest part of his/her chest. Make it snug but be sure 2-3 fingers can fit in between the measuring tape and your dog. If you don't have a soft measuring tape, take a string and wrap it around your dog. Then measure the length of the string.
