But I am not so sure that this can be the causal factor for all the foot problems I see in recently deshod hooves.
The foot above (not one I have worked on) is most likely to have had a fair amount of farrier attention judging by the nail holes and interesting shoe pad combo. It took a long time for the foot to get like that.
To be honest, I am wary of posting pictures like the ones above. But unfortunately I have met horses still living, attached to feet that are going in the same direction. So I post with the hope that maybe these pictures will serve as a timely warning and prevent such tragedy happening for someone and their horse.
