Re: RC: RE: Fw: gaited: 50/50 chance

Lawton Johnston and I had several conversations about this issue. He rode many
different horses in his day. But he always was trying to cross his walking
horse mares with his Arab stallion to get a gaited half Arab. He gave up. I've
considered breeding my endurance walking horse mare with an Arab, but it would
be to get a good trail horse that could do the miles with a brian, not to get a
gaited half Arab. I would suspect, however, that the trot would be smoother and
flatter and that the spooks would be many fewer and much farther between. But I
wouldn't bet that the cross would be "gaited."
