Our medium harness is ideal for dogs like Cocker Spaniels, larger Boston Terriers, or Beagles.
Harness length is 15 inches (38 cm). Girth is 25-32 inches (63-81 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.
