I'm having some trouble with my harness and I'm thinking may be I'm not putting the saddle in the right place. Does it go behind the withers, or over the withers. I've been putting it behind the withers. But since the girth area is more forward, the saddle tips back a little. Then the thinner staps coming off of the saddle that connect to the shafts are going more backward, putting pressure on my horse. I noticed from a photo, that my horse's previous owner had the saddle more over the withers. Here's a couple pictures from last weekend. Hopefully you can see those straps that go to the shafts.
