Im so sorry for your loss. But I do know how u feel. Just a couple of weeks ago a stallion I coown was found with the same thing in a back leg. He had been in his pasture too. So I do know and am very sorry.
OMG!!! I am so, so sorry to hear of the loss of your girl. I know it is hard to say goodbye to such a dear friend. I hope that your heart heals soon. I imagine that your friend is crushed by this as well. That is way I am always scared to have another horse at my place, accidents do happen. ((((HUGS)))
Oh......... I am SOOOOOOOOOOOOOOOOO sorry to hear about your loss! My heart goes out to you! How horrible!!!!!!!! What a freak deal for something like that to happen!
