NOW, I have found a MASSIVE cut on her neck, probably from barbed wire!! It's very deep, but by the time I got to it it looked like it was already healing up nicely. Regardless I cleaned it out and treated it with antibiotics. I just don't know how she keeps doing this to herself! She's not a very clumsy horse. She's never had really bad cuts before, just small little scrapes here and there, but this one is big! Thankfully it doesn't seem to be hurting her at all! Here are some pictures:
This is when I first found it and before it had been cleaned. Picture doesn't do it justice to how gross it looked..
This is after I carefully hosed it out and put some antibiotics and SWAT on it.
