Animal Euthanasia

Animal euthanasia (from Greek, meaning "good death") is the act of humanely putting an animal to death or allowing it to die as by withholding extreme medical measures. Reasons for euthanasia include incurable (and especially painful) conditions or diseases, lack of resources to continue supporting the animal, or laboratory test procedures. Euthanasia methods are designed to cause minimal pain and distress. Euthanasia is distinct from animal slaughter and pest control, which are performed for purposes other than an act of mercy, although in some cases the killing procedure is the same.

In domesticated animals, this process is commonly referred to by euphemisms such as "lay down", "put down", "put to sleep", or "put out of its/his/her misery".
