PetSafe harness sizing
PetSafe’s Easy Walk Harness covers chest girths from 30.5cm to 124.5cm across 8 sizes. Runs further up than most, which matters for giant breeds. It also uses wide size bands, so a single size covers a lot of dogs and adjustment matters more.

What PetSafe calls the same dog other brands would
Letter sizes do not travel between brands. A dog measuring 78cm around the chest takes PetSafe Medium, and the same dog is:
If your dog measures between two sizes
PetSafe’s ranges overlap on purpose, so a measurement landing in two of them is normal rather than a mistake. What decides it is where inside each range you sit: near the bottom the straps run near their tightest, near the top there is little adjustment left and a growing dog will outgrow it. The size finder shows that position for every brand at once.
