Size Information
The webbing on the harness is one single piece so the harness is very adjustable to different proportions. We recommend selecting a size based on the weight of your dog. Please size up if your dog is on the edge of the weight range.

Crash Testing Information

Our Impact harness has been tested up to 108 lbs. at an established University testing facility using the Federal Motor Vehicle Safety Standard for child restraint systems. See below for a link to the crash test report and videos for specific harness sizes and results.

Our Impact Harness initially passed for dogs weighing up to 130lbs at the University of Michigan testing facility in 2016. Since then, we’ve refined our dog dummy for accuracy, and improved our testing standards. The Impact Harness passed the crash test at Calspan in 2020 for dogs weighing up to 108 pounds using current PPSC testing guidelines. The new crash-test dog dummy has been vetted and will be the standard going forward for PPSC tests. In our effort to act as a leader in the dog safety space, we will continually update our crash-testing methods as industry standards change.
