Look at that skinny neck! And you can see how prominent his withers are.
And here he is with the Equi Measure mold on when I first made it to send off for his saddle fitting.
And here are the recent photos of him - you can see that now he's a bit overweight (hey, it's January!) but also that his back has completely changed shape and he's gained a lot of muscle development. He's been in regular work and just isn't the same horse anymore. No wonder he needs a new saddle!
