It is visible in white hooves. Hence, it occurs more often than is "visible", b/c it won't show up on black hooves as well. Many things can cause it. However, if you think back and really review what she did "then", it might help. This has occured on my mare (white hooves) when she went from soft ground to ridden on hard ground (extremely hard, I.e., solid rock). My mistake. It appeared as "blush rings" on the outer hoof wall below the coronet. I called the vet. It was nothing to get excited about. And, when the rings grew out to the point I rasped them off, it did look like I hit blood. However, there are several other less "benign" causes. Maybe some of the experts will chime in with the "other things".
There is just as much horse sense as ever, but the horses have most of it.
