Saddle shopping is bad enough as it is without trying to predict how the horse will look in two years.
My horse is 25. My mom needs a saddle. I’m trying to get her something that fits now while also leaving room to shim what might need to be shimmed in a couple of years. Generally speaking, between age and having 3 months of light work care of Covid, his lats and abs are a little atrophied and he’s carrying his weight lower, causing more curve to his back. I might be able to get that back up a bit by the end of the summer.
How much did your horse’s back change with age, while the horse was still in light to moderate work?
