Its normal, my mares swelled to about an an inch and a half depth. They say you can rug straight after - IF you can get near the damned horse again. I couldn't get near mine in her stable for about a week, and for 6 months she freaked out if you went near her shoulder.
CrazyMare - I know what you mean, she is now a right stroppy madam this week lol, tries to bite my head of when I get near her. Bless her, dont blame her though - it was horrible...
Is the process painful for the horse? Thinking of having mine done only he has allot of under the skin sarcoid's and lumpy bits so just wondered if anyone has any experience of this?
