The first picture shows an extremely overgrown hoof. Although the picture is taken at an unfortunate angle, you may be able to see how the frog is choked off by excess sole and bar. In the second picture, after an extremely conservative first trim, you can see how narrow the apex of the frog is. In the third picture, just 13 days later, the choked off frog is free and the apex has expanded. In the fourth picture, six weeks after the first trim, the frog looks a bit ugly, but is in the process of replacing itself. In the fifth picture, just over three months after the first trim, the frog has regenerated nicely. At no point did I ever trim this frog-- not even the tags and loose pieces. I did, however, have the owner apply colloidal silver topically for about a week. Click on each of the pictures below for larger images and additional details.
