As the injury is healing, I seem to be taking the photos closer, so in comparison the wound itself does not look much smaller. However, you can clearly see the way the wound itself is contracting inwards.
As can be seen, the injury is now smaller than the palm of my hand. He still finds it itchy, but I guess that is to be expected.
Thankfully, he seems to have recouped any lost weight pretty quickly, and indeed the girth is considerably tighter. He certainly doesnt look like a big horse just standing there ... until you get a bit closer that is!
