Not much of an update today...I checked on her this morning and she still wouldn't put any weight on that leg but she tried to come to me for a treat. I couldn't bare to see her try, so I went out to her with a treat. Poor thing. I also went over after work tonight and she was happily eating at the round bale though I'm sure that she hasn't made any miraculous recovery at this point.
Ultimately, I feel that this is "their call" as far as treatment goes. I'm just not qualified nor have the knowledge as they do.
THis whole horse thing has been an ongoing learning experience and I've learned so much from this forum as well. Thank you everyone!
