A few days ago I noticed a crack in my horse's front, right hoof. No one was around to ask about it, but it didn't seem to bother her at all. I went today and noticed a crack in her other front hoof. The cracks are pretty much identical in regards to location and size.
I lunged her for about ten minutes and she shows no signs of either hoof bothering her. As you'll see in the pictures, the cracks aren't large, and they are both across the hoof instead of up and down.
I know it is kind of hard to tell in the pictures, but it is definitely a crack.
I'm just wondering if this is something I should call the farrier for and if it is even anything worth worrying about too much [since like I said, she shows zero signs of it bothering her at all].
