XX Small: 6-8 inchesSmall: 10-14 inchesMedium: 14-19 inchesPET CLOTHING MEASUREMENT TIPS:1. Measure your pet from the base of the neck to the base of the tail. This measurement is the length needed to determine what size clothing your pet will need.2. Always go to the next larger size if your measurement is within 1 inch of the maximum.3. We also recommend to round up to the next size if your pet has a broad chest, bulky build or thick coat.NOTE: Somewhat loose clothing is more comfortable for your pet and looks better than tight clothing. If in doubt, order the next size larger. Also, please keep in mind that certain breeds e.g. greyhound, dachshund or an over or underweight dog may need a custom fit.
