2.Hoof horn in an ideal dry climate. The horn will be hard, dry and strong. Because this horn is undamaged it will have a low porosity and will not readily absorb environmental water. As that is because most people think that is the problem. In reality wetting these feet never makes things better, but the myth continues in tradtion.
More water is never the answer.
The observer sees the hooves dry out and then assumes that the brittleness is due to a lack of water. I hope you now know better.
