We recently bought a paint and was told it just turned 3. Turns out we were lied to and it is actually 4 1/2 years old. It stands 13.3 currently however both parents were mid 15. I am extremely worried we will not get the height out of it her that we expected. I do not believe it had the best care and was under feed. What if anything can anyone suggest that I do to try to bring it around. Within 2 weeks we are already seen a change in overall looks and behavior.
