We suggest measuring your dog's actual neck circumference (using a string or soft tape measure) and adding 1 inch. This is the most accurate measurement. Measuring your dog's current collar can lead to sizing errors due to various buckle styles. Our measurements are taken from the tongue of the buckle (not the end) to the first and last holes for the most accurate sizing. Do not measure the end-to-end length of your dog's current collar as this measurement is rarely useful for an ideal fit.
