Yes, I lost my very first horse ever from colic. I had her for three weeks, she came to me way malnourished, and was not in a good situation. I became very attached to her in the short time I had her and it was one of the toughest things I have ever had to deal with. I am just happy that her short time with me was wonderful and that she had food and shelter and she knew love. I know it is hard, trust me, I have been there. He was in your life for a reason, even if it was for a short time. I have asked myself over and over what did we do to cause it, and there was nothing we did different. I beat myself up saying that somehow, it was my fault, but it could have been anything. Keep your chin up and remember, he is looking down at you and will always be with you.
