Good basic foundation training works for gaited and non gaited horses. I feel like if the gait is there, it will come out. Some horses are naturals and gait well from the get go where some take time to find their gait. Some never get a decent gait at all even if they are a gaited breed. It isn't rock solid in any breed. The closest one is the Peruvian. I have never seen a Peruvian not gait. Some do gait better than others though. You will not know until you work with your horse. Get that good foundation first.
