How to support a palmar hoof...

Photos of the same horse 6 months apart. This foot was in pretty dire straits. 

Isn't it interesting to see how it has changed without remedial farriery or trimming...

Contrast the relative positions of the frog and heels; the other key changes are the development of the digital cushion and the shorter, stronger hoof wall. 

Much greater mass at the back of the foot. There is old damage on the lateral bar but that is growing out and not causing any problems at the moment.
