I trimmed up Chanti's front feet myself to prevent her feet from cracking. Her left front has always had a crack, you can see it from the bottom of her hoof to her coronet band, and when her foot gets long it starts splitting at the toe so we touch it up with a rasp as needed. All I use is a rasp and once in a while I use the hoof knife to trim away flaky frog, if it's peeling and already loose. I admit I'm not by any means a pro but I'm not completely stupid when it comes to trimming and I feel I can handle touch up trims like this.
So first will be before the trim of the left front. And second is the sole view. On the right side, right at the bar, there's an area, like a flap that I couldn't trim off with the knife. I could get up and under it with the hoof pick and it felt like there was a "pocket" under it. I didn't want to mess with it much because I wasn't sure what it was.
3rd pic is the after pic, and 4th is after the trim showing the sole. I don't use the hoof knife and dig any sole out and I had let her walk around and graze in the yard so her hoof was a little dirty.
Next post will be right front.
