A friend was riding Rosie on Saturday and near the end of the ride, she started favoring her left rear foot. I had her got off and I checked it. There was no heat in her ankle, and I couldn't see anything wrong. I still had the girl walk her the half mile back to the trail head (Would have let her ride Rookie, but she was too scared to get on him). I took her back to the house and by the time we got there, there was definitely heat in it. I cold-bathed it then checked it again. She is trying to shed her frog in that hoof, and on closer inspection, it looks like she had stepped on a rock and broke some of it off prematurely. She's walking fine after she's been out in the pasture, but I put both of them in their stalls during the day because of the heat, or if there is a storm with thunder and lightening coming. I notice that she's still favoring that foot when I first let her out in the evening.
So, my questions are:
1. Is there anything that I can do for her to make her more comfortable?
(My farrier is camping and doesn't have cell reception right now)
2. About how long does it take something like this to heal?
Thanks in advance for replies.
