furniture, George reluctantly took an experts advice and gently hit the

parrots beak whenever the bird started to chew furniture, The bird

stopped chewing furniture, but it is now afraid of hands and will

sometimes bite. Since Chewing on the furniture would not have hurt the

bird, George should not have hit it.

When Carlas puppy escaped from her yard, it bounded into a busy street.

Although Carla does not generally approve of physical discipline, she hit

the puppy sharply with her hand. Now the puppy enters the street only

when accompanied by Carla, so, Carla was justified in disciplining the

puppy.

Which one of the following principles, if established, would justify the

judgments about Georges and Carlas actions?

a) When disciplining an animal physically, a trainer should use an object

such as a rolled up newspapers to avoid making the animal frightened of

hands.

b) When training an animal, physical discipline should be used only when

such discipline is necessary to correct behavior that could result in seriousharm to the animal.

c) Using physical discipline to train an animal is justified only when all

alternative strategies for the correcting undesirable behavior have failed.

d) Physical discipline should not be used on immature animals.
