Stress is defined as
the biological responses an animal exhibits in an attempt to cope with a threat to its homeostatis
Pain is defined as
An aversive sensory experience representing awareness by the animal of damage or threat to the integrity of its tissues. It changes the animals’ physiology and behaviour to reduce the likelihood of recurrence and to promote recovery
Distress occurs
when the stress is of such magnitude or duration that significant changes in biological function must occur for the animal to survive
