Description Size Guide Health & Safety Care Review Warranty and Guarantee Help JK9® Speed - Built for top performance When “walk” just doesn’t cut it anymore, this harness steps up. The Julius-K9 Speed Harness merges rugged performance with comfort and control — perfect for active dogs and owners who move. The design of the padding of the harness was inspired by the seats of sports cars. Its inner surface is lined with neoprene, which does not absorb moisture and is easy to clean. It is pleasant to wear in all seasons and conditions. As the JK9 Speed is a short Y-shaped harness, it doesn’t bend back and turn sideways even if your dog prefers to run next to you. The harness’s German-made OEKO-TEX®-certified straps can be adjusted at five points, so they can be completely tailored to your dog. Optimised Y-shaped design: Keeps the harness from bending backwards or shifting sideways when your dog rockets ahead. Neoprene inner lining inspired by sports-car seats: Non-moisture-absorbing, wipe-clean, and designed for comfort across seasons. Five-point adjustment with German OEKO-TEX®-certified straps: Tailor it to your dog and keep it snug without squeezing. Heavy-duty leash attachment ring + sturdy back handle: Pull-up assistance for steep terrain or firm control when your dog’s got zoomies. Built by professionals in a European ISO 9001 factory: You get real quality, not just “dog gear”. TAKING YOUR DOG'S MEASUREMENTS CORRECTLY Place two fingers behind the front legs in case of sizes 2XS, XS and S, three fingers for size M and four fingers for sizes L, XL, 2XL. The neck girth should be measured at the base of the neck. If any measurement fits the next size, choose the bigger one.
