My Canadian gelding was put on biweekly farrier trims for April and May, then every 3 weeks farrier trims and just  changed  to every 5 weeks starting now..  This seems to have worked for him.  I also put him in Hoof Scoots for exercising only activity as this is more comfortable for him.  Being IR he needs regular exercise.
