Sheep
When confronted by obstacles, they hate to make decisions - deferring instead to their partners or their religious leaders. While this may help the sheep maintain a superficial sense of well being, it leads to the loss of identity that typifies the sheep persona.
Their reputation for lack of vision and ambition is well deserved. Largely disinterested in politics, viewing it as time taken from work, sheep respect the law and never question authority. This leaves them susceptible to the whims of the canine personalities, who with their dominance and leadership are able to change the direction of an entire herd. Like most things in life though, sheep turn this into an advantage by utilizing the protection and guidance provided by these stronger animals.
