Just a quick sanity check if I may? My 4 YO NF has gone bum-high again. He's about 14.1hh and a bit at the bum, 13.3hh at the wither. He is supposed to make at least 14.1hh so I am hoping this is the start of a growth spurt. He's been in work for about 2 months, mainly hacking with one gentle schooling or lunging session per week. However, now he's gone up again, I think he needs a bit of time off. I spoke to some other horsey types I know who say I need to just carry on but I don't think that's a good idea for a pony that I want to last into his twenties and remain sound. Am I right or being over-cautious? Thanks!
