I'd call the farrier again. Is there a nail that is higher than the rest that could be pinching? I've this before and farrier came out the day I called him and sorted her out.
it doesnt matter now. Mum has texted me and shes fine
She had them front shoes on like back ones with 2 clasps now she has 'normal' front shoes on and i think it might of just been a bit different for her. But shes ok now
