I have a gelding thats 14h and a sport horse - I thought anything under 14.2 was automatically a pon. His mother is a pon and his father is a sport horse that produces pons.

I think he is still growing. When you use a lens of time on him, it says his final height is 14.3

Do they grow past age 3?

It takes 60 days from birth to reach final height. So if they were born late in the month they can still be growing at 3.

Ahhhh. Thank you!
