Doris: I would be concerned about the weight with the fact that she was
probably small at 26months (since she is 15.1 now) and how it timed with
her growth spurts. If she was sloping downhill quite a bit while you were
riding, it doesn't matter how light it was, it may have been extra stress
on the front. Remember, growing babies might have a lot more than 60% of
their weight on the front and add the weight of rider and tack?.... I would
recommend having her looked at by a competent veterinary chiropractor and
make sure the problems are gone. Some outgrow them and some don't. It
never hurts to check.
