This is a 15-year-old quarter horse mare. She has some soundness issues. If you look at the first picture you will see that on the left side she is missing a portion of her hoof wall. On the right side, you can also see the weakening of her hoof wall. This is because her hoof wall has poor quality of horn. Before we shoe her, we are going to need to cast her hooves for at least 4 weeks.
