KONG Ultimate Car Safety Dog Harness, medium

Pets at Home reports independent crash testing to ASTM F3725-25 and FMVSS 213 frontal conditions. The seat belt runs through the harness handles, so you don't buy a tether. Medium fits a 38 to 91 cm girth and a 35.5 to 91 cm neck, but the page gives no weight range.

What the label and listing say

Chest girth	38 to 91 cm
Material	Heavy-duty reinforced webbing
