Most horses go hopping lame etc etc but there are always the odd ones
My horse had an abscess that took 7 weeks to rear it's ugly head, no heat, no raised digital pulse, only 1/2 10ths lame....after 7 weeks he went much lamer and pus was located but took a long time (he is quite a tough boy, quite stoic and has good feet with thich soles). Hope that helps
vet and farrier already been about 3 weeks ago so we were just waiting now but yesterday when i picked foot out one side started really crumbling and a hole sort of came but no pus
