Showing is a good way to add value to your tiniquine. If you have a tiniquine that is a four or five time halter champion then he is going to be worth a lot and so will his foals, as they are would-be winners.
Another good reason is if you have a tiniquine that wins halter shows you have an even better chance of him winning the next halter show because they get one more chance of winning for every show they win.
Also, some breeders only allow show winning mares to be bred with their stallions.
More to come as I think of them.
