This dog jersey uses three measurements, L (LENGTH FROM NECK TO BASE OF TAIL), G (GIRTH AROUND CHEST), and N (SIZE AROUND THE NECK). The most important measurements are the GIRTH and NECK. NOTE: These jerseys run small. We provide the manufacturer supplied measurements here. However, if your dog is at or above the middle of either the Neck or Girth measurement, we strongly suggest ordering up one size.
X-SMALL: L:6-9", G:15-17", N:6-8.5"
