My dog is new to pulling anything so this harness helped a lot to keep the introduction easy and nice, it fit well, the straps adjusted perfectly for his size, and while a little confused, it was a lot better then using any old harness, and he didnt have any problems from it, it didnt rub his skin or seem to cause any discomfort from pulling. Overall its a great harness, and from when I inspected it, insanely sturdy, and built to last. Its definitely worth the money if you want a good harnes for your dog to start sled dog training, or pulling carts.
