Euthanasia in Animal Welfare: Principles and Practice

Humane euthanasia is a welfare-positive tool for ending unrelenting suffering; understanding principles and methods guides better decision-making.

Key Facts

The AVMA defines euthanasia as causing death without pain, distress, or anxiety
Carbon dioxide euthanasia for rodents causes some distress before unconsciousness
Intravenous barbiturate is considered the gold standard for companion animal euthanasia
The decision to euthanize is often delayed too long in companion animals causing unnecessary suffering

Welfare Considerations

Euthanasia is a welfare tool — the ability to end suffering that cannot be adequately controlled is a genuine welfare benefit. Delaying euthanasia to spare owner distress prolongs animal suffering. Choosing the most humane euthanasia method available is an ethical responsibility. Quality of life scales help owners and veterinarians make more objective decisions about when euthanasia is the welfare-positive choice.
