I have recently (3 months ago) bought a 4yo Highland who lives out 24/7 and when I bought him he had fronts on. I had them taken off straight away as neither of my other natives are shod and do perfectly well without. However he is struggling on stony ground and looks slightly unlevel in front in the school. Leading in from the field he will avoid stones. He is fed regular hay, happy hoof, pony nuts, micronised linseed, s beet, top spec. Any advice please? Or should I just give in and out fronts on him?
