Much depends on the horse, the new owner and the discipline or activity they plan to undertake. Some horses have been re-homed in under one month; others may take three to six months, or longer.
When ex-racehorses first come to HEROS Charity we give them a period of rest and play in the field. They need a bit of time to get racing out of their minds and it also takes some time for us to understand their abilities and needs.
