X1 Dog Harness

Utilized by mushers and working dogs around the world, our X-back harnesses are built to fit comfortably even when the dogs are pulling hard. Each harness is from a continuous piece of webbing for maximum durability. They are lined around the dog's neck and on their chest with either soft fleece or padded nylon for comfortable running or walking.

As a single piece, non-adjustable harness, proper sizing is extra-important. Measure the dog's collar size, weight, and back length to determine sizing. Utilize the example and the chart below for reference.

    This harness does a fantastic job with our 2 year old GSP Annie Oakley and her love of running with my husband. I’m also 100% sure it also saved her life. Today while running along a trail she ran into a branch that had overgrown the trail and wasn’t visible at first. The branch snapped. Her harness saved her from being impaled and all she has to show for it is a small abrasion and maybe some bruising. I will always be grateful for the incredible craftsmanship that went into this harness. Thank you.
