32) After several attempts to district his young parrot from Chewing on
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.
