This size is perfect for Cavalier King Charles Spaniels, Boston Terriers and standard size Daschunds.
Girth is 16-26 inches (42-67cm) and the harness length is 12 inches (30 cm).
**Keep in mind, the length is not always the most important. Fitting the girth snuggly to keep the harness secure and covering the most vital organs is best.
All measurements are approximate.
