Nursing Foal Imbalanced Syndrome
Notice how the inside (medial ) is lower than the outside (lateral). The foals are in nursing position all day long and wearing out the medial side of the hooves because stabulated horses don't travel 25 miles a day like will do in the wild so is very important to rasp those tender hooves every 3 weeks during their first 6 months of their lives to compensate this cycle.
The grey horse's knees and hooves are not properly aligned......Bay horse's knees and hooves are properly aligned. You only have 6 months to correct before the phalanges of the pasterns closed up for good.
