Bim was happily nibbling at a bale of hay id left in the field shelter when she began to cough, when i went over to her i realised she had stopped eating and was just stood. Then she went all rigid and like she was trying to cough something up. I took her out and into the field and walked her round gently rubbing her throat and she kept stopping and doing it. Then she stood for a while and then began grazing. Shes been fine since but looks a little drained and fed up. Shes grazing in the field now. Why would this happen - its never happened before?? Did i do the right thing?? Is there anything i should look out for now with her?? Is there something i should do in future to prevent it? are horses who have choked once more prone to it?? Ahhh questions questions - it was awful to watch
