I hope they can get this done....

[Pedigree Ann]

Northern Dancer bred some larger mares, even though he was vertically challenged himself. I think he had a ramp for help with altitude. Unfortunately, 'fish and fowl' matings (those with parents from extreme ends of the spectrum) often end up one or the other, not the average. She probably needs an 'average' sized mate to keep her baby from being so big it won't fit in the gate.
