If your dog is between two sizes
Carhartt publishes advice for this, so use theirs rather than a rule of thumb:
“between sizes, size up”

This site treats a measurement within 1 in of the edge of a size, or inside two sizes at once, as between sizes, and shows both. Work it out with the harness calculator, or read how to measure your dog.

How to measure for this harness
Carhartt sizes this harness by chest girth.
Run a soft tape around the widest part of the rib cage, just behind the front legs, and keep it snug but not tight. Two fingers should slide under it. Measure twice: a tape that has slipped an inch is the single most common reason a size is wrong.
A number off this chart is where to start, not a fitting. Measure your dog and check Carhartt’s own current chart before you buy.
