Our SMALL harness is meant for Cavalier King Charles Spaniels, Frenchies, Boston Terriers and Min Pin sized dogs. Dogs are all different sizes though, so going by the sizing chart is the best idea, not the breed. Contact us if you need help.
**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.
