Weight pull and Sledding Harness Sizes

Above sizes reflect pretty well any size of dog. The best way to fit a harness on a dog is to measure it from base of neck to tail 'root' and around the neck (plus the weight of dog). 

For Scootering, Biking, or Sledding (H-backs available in mid-range sizes too). These harnesses are well-made and especially good for large dogs such as Alaskan Malamutes but sizes to fit Siberian Huskies, Samoyed, Alaskan Husky and non-traditional breeds also available. All new. The harness should be snug and come to the tail base when pulled tight. The tail shouldn't come through the harness and should not be up the back when tight. Broken fur under the front legs and around the neck can be a key sign of poor fitting - or cheap, abrasive material. Poorly-fitting equipment is a prime reason why a dog won't 'work' - and can be hurt!

Weight pull harnesses are properly spread for freighting or weight pull, are good for competition or fun and have a spreader bar. My dogs have won many pulls and 'gold, silver, bronze' placements in them! All new. The spreader bar should NOT come below the hock on the dog, though many, many people do fit them that way. Experienced dogs probably wouldn't tangle but inexperienced dogs WILL tangle on a low or wide fitting pull harness, possibly breaking a leg. The harness should be snug and allow room for the tail to pop up, with a small amount of room around the butt. Poorly-fitting equipment is a prime reason why a dog won't 'work' - and can be hurt!
