I've just checked on my horse after feeding her dinner and she's injured her NS fore - looks like a cut on tin (don't quite know how she's managed it!). It's not bleeding much, looks like only the skin has been cut. I've washed the wound, filled it with honey, sprayed over that with purple paint and then covered with vet wrap. What should I do next? How often should I change the dressing? Any better ideas on treatment??? Thanks!
