Worth checking: The Large girth is printed on the chart as '29.5"-425"' (typo). 42.5 in is taken from PetSafe's own 3 in 1 + Two Point Control Leash page, which states 'girth measurement 29.5-42.5 in; neck measurement 24-38 in': https://www.petsafe.com/p/3-in-1-harness-two-point-control-leash/3IN1-TPC-LSH-S-BLK/
Note: PetSafe support says: if your pet falls in between sizes, size down (https://support.petsafe.net/articles/how-to-measure-your-pet-for-a-petsafe-3-in-1-harness/).
If your dog is between two sizes
PetSafe publishes advice for this, so use theirs rather than a rule of thumb:
“if your pet falls in between sizes, size down”

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
PetSafe sizes this harness by girth (shoulder also listed).
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 PetSafe’s own current chart before you buy.
