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

How to measure for this harness
Wild One 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 Wild One’s own current chart before you buy.
