I understand that horses are not finished growing until all the bones are done, however.... How old are they when they reach full height and just need to do the finishing? When do you say okay that is about the height she/he will be. Just the filling out and bone finishing left. I have two yearlings but don't know how much height is still to come. They have grown about 1/2 a hand since the spring. Will they keep growing past 2 years of age.. up to 3 years? I'm trying to get an idea of how tall they will be when they are finished. My Gelding is 14months and 14 hands. My filly is 15 months and 14.2 hands. I know there are varibles to keep in mind and I believe the growth will slow.. but these are my first babies and I'm familiar with when they stop. Dogs most have full height about 6mos but then are not finished growing until they fill out and mature. Horses?
