End-of-life decision-making for horses is one of the most emotionally and ethically challenging aspects of horse ownership, and welfare-centered approaches prioritize the prevention of suffering over extension of life.
The welfare imperative in equine end-of-life care is to prevent a prolonged period of suffering by making timely, courageous decisions about euthanasia. Horses do not benefit from extended life when that life involves chronic unmanageable pain, inability to engage in basic behaviors, or progressive deterioration toward a more distressing death. The emotional difficulty of euthanasia decisions for owners is real and deserves compassion, but this difficulty should not be allowed to extend a horse's suffering. Veterinarians and equine welfare advisors have a responsibility to provide honest quality of life assessment and to support owners in making timely decisions.
