Kurgo
An affordable five-point-adjustable harness with all-steel nesting buckles and an included carabiner tether. Kurgo publishes a June 2018 Calspan report showing small, medium, and large v3 units passed the manufacturer's adapted FMVSS 213 criteria for structural integrity and excursion, up to a stated 75 lb test range. This is manufacturer-commissioned testing, not current CPS certification.


Ruffwear
A padded, strength-rated car harness with a universal seat-belt loop and manufacturer-published dynamic testing under FMVSS 213 conditions. Ruffwear explicitly states that Load Up is not CPS certified and that its tested forward-excursion result would not meet CPS's current certification limit; that unusually clear disclosure makes it a stronger research choice than vague 'safety-tested' restraints, but not equivalent to the two certified picks above.


Sleepypod
Sleepypod's current next-generation three-point car harness, offered in Regular and Long body-shape versions. The official page states independent CPS testing earned a 5-Star rating across an 18-110 lb range, while CPS currently lists Clickit Range among its certified harnesses. A sizing quiz and exact shape selection are important because the design deliberately limits torso movement.

Säker
A modular trail-and-car harness that is currently listed by Center for Pet Safety as a 5-Star certified safety harness in XS through L. CPS reports a November 2022 test under protocol CPS-001-014.01 with a 75 lb test dog; that independent certification is the main reason it ranks first, not a claim that it eliminates crash risk.


Orvis
A full-coverage hammock offered in Compact, Midsize, and Full-size formats, with a mesh window, side skirts, zippered seatbelt-receiver openings, Grip-Tight backing, and cushion-gap handles. The machine-washable fabric uses substantial post-consumer recycled content and a microweave intended to mask fur. It is only water resistant, requires adjustable front and rear headrests, and its official review presentation was inconsistent during verification, so it receives the most conservative score here.

K&H Pet Products
K&H's Bucket Booster uses the vehicle belt beneath its cushion, raises the dog about 5.5 inches, and includes two interior tethers for harness attachment. It offers a more supported, padded perch than a hanging booster, but K&H publishes no pet weight limit on the current page and this research found no current crash certification for the seat.
