My pick for Product of the Month is the X-Back harness by Alpine Outfitters! This is the pulling harness that I use with both of my dogs for the various activities that we do where they're hooked up to something. These harnesses hold up incredibly well and I've had no problems with any parts of them rubbing my dogs raw. Because great danes aren't the typical northern breed that you see out there doing a lot of the various pulling sports, I had both of my guys actually fitted for their harnesses by a member of their company. You might think that a custom fit harness would be a lot more expensive than a ready made one, but I think that it only cost an extra dollar or two. Definitely a really great deal! And you can even get your dog's name on the harness!!
I do spell Heffner with two f's, but there was a misprint on the original form that I never got fixed (the harness in the above picture is also a little big on Heffner and we've since had it modified so that it fits better).
