so. my paint horse is 3 and a half years old. he has had his BIG growth spurt. like a hand in 2 months when he was 2 years old.for the past two months i have been jumping a little bit. like at most a foot once a month for about ten minutes. i was considering keep doing this till hes old enough to get into serious jumping training. i heard these small jumps are actually good for his muscles and mind. because hes a baby he will get to focus on something without being over worked. well my question is. what do u think?
