I have a Clydesdale mare that I bought August 12, 2009. She is my dream horse I've been saving up for literally since I was 2. When I bought her all her breeding rights were carried through with her papers and name and showing documentation. She's 10 now, 11 April 2010 and I really don't see myself breeding her. I use her for pleasure riding and she's wonderful with my friends kids, perks her ears up for the camera for my photographers during photo shoots. She's everything I could have asked for in a horse. I know she has foaled 3 times in the past and have met her most recent filly that is now a year old. All her foals have been healthy and gone on to showing. She has great lines and would make a great mother again no doubt. So if for some reason I change my mind and want to breed her, how many years do I have left to safely breed her.
