Retirement and end-of-life management for horses is a significant welfare challenge. Understanding what good retirement looks like and when euthanasia is the kindest option guides responsible ownership.
The welfare of retired and elderly horses depends on owner commitment to ongoing management after the horse is no longer in productive use. This commitment is tested by the costs — veterinary care, farriery, dental care, and housing all continue regardless of whether the horse is working — and by the emotional difficulty of recognising when retirement has transitioned to deteriorating welfare. Horses with managed Cushing's disease, controlled arthritis, and appropriate body condition can have excellent quality of life in retirement for many years. But the decision to euthanise — when pain management is no longer adequate or when quality of life has deteriorated irreversibly — is one of the most important welfare decisions an owner makes, and making it too late causes unnecessary suffering. A good death is a welfare goal, not a welfare failure.
