Our racehorse can no longer race

We need to go back a little bit. We've known for a long time that Cotton had caught some sort of virus. We're not sure how she got it, could gave been the  feed or another horse. Under normal circumstances she did not suffer any ill effects. After a race though she would cough up blood and mucus. The only cure was rest. We let her be until April of this year and we were optimistic when she started galloping at the farm she was staying at in Pennsylvania. Unfortunately we found out a few weeks ago that the blood and mucus symptoms started up again after she was doing a  slow gallop.

It's really disappointing as we know Cotton can run. From her debut race when she caught up with Balooga Bull ( only the Horse of the Year winner for 2012 at Assiniboia Downs)  to her maiden victory in late September 2011 to her competitive races against other horses who have gone on to win significant dollars...we knew we had a racehorse. It's truly sad that we'll never get to see her full potential.

 There's nothing we can do at this point to turn Cotton back into a racehorse but, with some help, she can certainly make more racehorses. Now how do you do that again ?
