I have a 1/2 arab 1/2 foxtrotter right now, and he doesn't
gait under-saddle. I have seen him gait in turn-out, and have
been told by a couple of "wanna-be" trainers that they could
get him gaiting for me... but it's not that important to me.
So, even though the "wiring" is there to gait, it doesn't seem
to be natural for him to gait...
My sister has a full foxtrotter, and she RAVES about how
much more comfortable she is riding his gait, rather than a
trotting horse, on the trail. She has had tons of problems
with her back & knees prior to this horse, but now seems to
be in 7th heaven.
Hope you find what you are looking for,
