Determining the correct size for your working dog's Tactical Dog Harness isn't an exact science. Here at Shark Fin Gear, we strive to ensure you achieve the ideal fit. That's why we offer five sizes tailored to most breeds that are doing scent work, search and rescue, and apprehending suspects. Consult the sizing charts provided below to gauge and equip your dog with the appropriate harness. Additionally, once you've placed your order, be sure to watch our instructional video demonstrating how to properly put on and adjust an SFGC harness.
