Ok so today I went out to my horse who has been in the field on her own for 6hours a day in a flat field fully fenced with stud railing. So I was checking her legs as she is super injury prone and on the back of the fetlock on the right fore right where she bends it there is a huge gouge out of it the skin is yellow and its very deep oddly though there was slight little crusty bits of blood on the hairs but in the actual cut there was nothing when I squeezed it first pus came out then this clear fluid? It is not hurting her as she was fooling in the paddock all day and I walked her around she was very happy not lame at all. So I stood her down stream in our fresh water river for 40 minutes which seemed to clean it there was no heat or swelling in it. I then cleaned it with a water and tea tree mix to make sure no dirt from the river was in it and wrapped her leg with the cut coated in manuka honey. Does anyone know what else I should do to prevent the infection travelling up her leg?
