I just noticed this today. This is the same hoof. Dexter's left front. The top left picture taken in January right after deshoeing him. The top right taken 8 days ago (that's marking pen at his toe) and the bottom one was taken last Saturday.
(Now of course this is not a trim I would perform on a healthy hoof. This is a trim I would perform on this horse's left front foundered hoof because I want to see if I can trim him in a way that will help him. )
Interesting changes. Not just between the first two pictures, how his heel is much wider, but also it appears to me in the 3rd picture after only a week, his frog got busy! So then I took the forces nearly completely off his hoofwall, (off his laminae). I can't wait to see what his hoof will do now. It never ceases to amaze me the capacity these hooves have for healing themselves if you can set them up for success.
