Explore our real-dog fit examples to see how each harness size looks. These examples describe our featured dogs; dogs of the same breed can need different sizes. Always compare your dog’s measurements with the size chart before ordering.
XXS — Smaller Dachshunds
A snug, comfortable fit for the smaller Dachshunds featured in our guide. Larger Dachshunds may need size XS.
XS — Cavoodles
Our Cavoodle wears XS for a neat, close fit that sits comfortably around the chest—ready for everyday strolls and little adventures.
S — French Bulldogs, Corgis & Cocker Spaniels
From our French Bulldog’s sturdy frame to our Corgi and Cocker Spaniel, size S gives each dog a snug fit around the body with space to step, sniff and explore.
M — Border Collies & Kelpies
A comfortable, secure fit for our Border Collie and Kelpie models, with room to move freely.
L — Boxers & American Staffordshire Terriers
Our Boxer and American Staffordshire Terrier wear L for a well-proportioned fit across their broad chests, combining everyday comfort with freedom to stride into bigger adventures.
