Duke our 8yo TB gelding, while bucking out at another horse in his stable (who bites him ) got his legs caught in the rungs and in the process of removing them has skinned a section of his rear leg (approx 30cm) while its ugly and hairless not bloody, we have been using pink spray it does not seem to be bothering him. But he also appears to have a small puncture wound just above the larger skinned area. Tiny in size but today has a clear discharge coming from it and feels warm to touch. All the fellow agistees say there is nothing we can do except keep it clean and run cold water over it. We have also been using a green antibiotic paste on this wound on their advice. How long should this take to clear up and what signs should I worry about. Also any suggestions on pain relief for horses (that dont need a vet). He is eating heaps of hay, but off his chaff. All feedback welcome.
