Goal for euthanasia
CVMA position statement:
“The animal must be rendered irreversibly
unconscious as rapidly as possible with the least
possible pain, fear, and anxiety. The preferred
methods used to achieve this are those that affect
the brain first, followed quickly by cessation of
cardiac and respiratory function. The experience,
training, sensitivity, and compassion of the
individual carrying out the procedure are critical”
