2. Animal euthanasia (euthanasia from Greek: "good
death") is the act of putting an animal to death or
allowing it to die 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.

4. Unconsciousness, respiratory then cardiac
arrest follow rapidly, usually within
30 second.
Generally describe the method as leading to a
quick and peace.
For large animals, the volumes
of barbiturates required are considered by
some to be impractical, although this is
standard practice in the United States.

5. Gas anesthetic such as isoflurane and sevoflurane
can used for euthanasia of every small animals.
Death may also be caused using carbon
dioxide has been achieved by inhaled anaesthetic..
Carbon monoxide is often used, but some states in
the US have banned its use in animal shelters:
although carbon monoxide poisoning is not
particularly painful, the conditions in the gas
chamber are often not humane . Nitrogen has been
shown to be effective, although some young
animals are rather resistant and it currently is not
widely used.

6. Cervical dislocation or displacement (breaking
or fracturing) of the neck, is an older yet less
common method of killing small animals such
as mice.
Performed properly it is intended to cause as
painless death as possible and has no cost or
equipment involved.
The handler must know the proper method of
executing the movement which will cause the
cervical displacement and without proper
training and method education there is a risk of
not causing death and can cause severe pain
and suffering. 6
7. When intravenous injection is not possible,
euthanasia drugs such as pentobarbital can be
injected directly into a heart chamber or body
cavity.
While intraperitoneal injection is fully acceptable
although it may take up to 15 minutes to take
effect in dogs and cats and intracardiac (IC)
injection may only be performed on an
unconscious or deeply sedated animal. Performing
IC injections on a fully conscious animal in places
with humane laws for animal handling is often a
criminal offense.

8. This can be an appropriate means of euthanasia
for large animals (e.g., horses, cattle, deer) if
performed properly.
Free bullet Traditionally used for shooting
horses.
Captive bolt Commonly used for cattle and
other livestock. The bolt is fired through the
forehead causing massive disruption of
the cerebral cortex. In cattle, this stuns the
animal, though if left for a prolonged period it
will die from cerebral oedema.
