Note, The mare is pregnant so penicillin isn't an option. Also note, her back end isn't the easiest to handle as she had a rough first five years of life (she is six). One more note, The vet was called out and he said little more than he cannot stitch it due to its location.
The day of -
Three days later (today - pictures taken before it was cleaned)
She was stalled for the first two days and has been turned out yesterday/today. She doesn't let you handle her back legs the greatest so I haven't been able to wrap it. She will let me get a few splashes of water on it but not much more, no scrubbing with a cloth and no cold hosing.
I did use betadine the first day. Since then we have been splashing water and applying lavender oil and yarrow powder three times daily.
The vet said tucoprim powder was safe for her and she will be on that for a few more days.
Suggestions? I am worried because it seems to be opening more than closing but this is of course do to the little bit of swelling. And it has gone done since yesterday.
