We once bought a farm that came with a horse. The couple that owned it before us just lost interest and let him run wild around the place.
He was in terrible condition when we took over. He had been a racing horse and hurt his back, so it seemed like he wasn't of use to anyone.
And they had let his teeth and hooves grow wild, so they both needed to be cut back.
His hooves took forever to heal, as they needed to grow out cracks. The farrier just came back every few months and kept trimming them.
And it was fascinating to watch a farrier floating a horse's teeth.
I think he was a lot more comfortable after we were done with all his doctoring. He had a sweet personality and it was criminal how they had neglected him.
