I was out riding and I came across 2 stallions ( I know, not good on a flirty mare haha) and they came trotting over, and they had their whole muzzels covered in raw sores. I'll attatch some images, but I was wondering what the h3ll it could be!? Their field... wasn't in the best condition, but there was nothing along the lines of poisinous plants or trees around... Perhaps some buttercups, nettles and little blue flowers. But I know the nettles and little blue plants don't do this. And there was planty of grass for these boys. It almost looked like really bad mud fever all over their noses, or real bad ezcema in humans.
The images are bad quality as there from my phone , but the sores were scabby and the skin was broken and red under the scabby bits.
