Most harness complaints — chafing, escaping, still pulling — are fit problems, not product problems. This guide shows you exactly where to measure, how to read a size chart, what to do between two sizes, and how to adjust a no-pull vest so it works the way it should.
Pulling isn't defiance — it's physics and instinct working against a standard leash setup. A well-designed no-pull harness changes the mechanics, not just the training.
