My paint mare is 2 years-old and is very small for show. She is approximately 13.1-13.2 hands and will probably only be about 14.1-15 hands. That of course is too small for show. Any ways to help her growth?
What kind of showing do you want to do with her? I didn't know there were height requirements in shows. In the hunter world, you have pony classes. Besides, my horse didn't actually stop growing until she was about 5. You have some time. I don't know of any supplements you can give to help the height issue. There are ways of bulking up your horse, but not with height.
What breed is your horse? Because whenever my mare gets WP down well I will train her for English Pleasure and HUS, so I would just prefer her to be bigger, and she is a paint-that looks like a qh- so she would just look better big.
