Ok, my young warmblood is again going through another growth spurt and has become completely unbalanced again. She was backed lightly as a coming 3 year old and worked on forward and straight. We started working lovely for the past 3 months. She got her rhythm, started to come nicely into the contact and her transitions were getting much more balanced, even the downward. This last month has been a devil of a time. She wants to over bend, fall out and totally lost her balance. She cross fires at the canter on the ground. My trainer told me the other day she is indeed going into another growth spurt and is completely croup high. She is weak in the hind end and poor thing can't balance for anything. Question is, how do you know if you should just let them have a few months off to grow and come back to work or to work them through the growth spurt. She is coming 4 yrs old now but still a big mare and growing. She is reaching 17 h. BTW, she has been vet checked and consulted with experienced trainers. All her issues are related to lack of strength and balance and not a soreness/lameness issue.
