Euthanasia for companion animals facing terminal illness or severe suffering represents an ethical responsibility and a welfare benefit unavailable to most humans.
The ability to end suffering through euthanasia is a profound welfare benefit available to companion animals and not to most humans facing terminal conditions. The ethical responsibility of companion animal ownership includes the willingness to make end-of-life decisions based on animal welfare rather than owner grief. Veterinary guidelines are clear that fear of euthanasia causing unnecessarily prolonged suffering is a welfare failure.
