Pardon not getting back to you - & haven't got time now either, but leaving this thread open, to remember to do it when I have spare time. Hope his leg heals quickly. If you're getting hoof xrays, make sure the vet marks the dorsal wall, dorsal hairline & apex of frog at least. Good also to have them stand on something that will allow for accurate measurements, such as a board with nails(cos radio-lucent) spaced evenly or such.
... & it will be fun if I mark your pics including where I suspect P3 is, then get to see rads & whether I'm accurate or not!
