Local horse rescue was called to assist with emaciated mare today. Mare is estimated to be around 30 and in very rough shape. She went down shortly after arriving at the rescue farm and it was decided to let her go. That being said, we would like to know who she was. The tattoo is basically illegible. We have a few ideas based on estimated age, color, markings etc. I've seen where people have been able to look up who they think an OTTB is and compare markings and such to verify. Where/how do you do that? And is there somewhere that states if the horse is recorded as deceased?
