I have two mares also, and being both responsible as a horse owner, and absolutely burning at the number of people who breed any animal at the expense of others that already exist, I have never and will never, breed either. The one mare comes from an old, previously well known Arab blood line and has the smoothest movement, and the other is the prettiest Anglo-arab I have ever seen, more Arab than Thoroughbred.
I also have a couple little dogs and when we got the second little guy, our neighbors fell in love with him and promptly went out and got a little female with the idea that when she was old enough, they would let their little dog be bred by ours. We neutered Diesel before that could happen. So we not only talk the talk, but we walk it too.
