A lifetime of abuse
Undercover video shows elephants being repeatedly beaten with bull hooks and electric prods. Wild animals used in circus acts are routinely beaten, poked, and shocked with electric prods, all to force them to perform unnatural tricks for an unsuspecting viewing public.
Trainers use these tactics to try to dominate wild animals and force them to act against their natural instincts. Tigers are made to jump through flaming hoops, elephants are forced to wear tutus or balance themselves on small balls, and bears are required to ride tricycles, just for our amusement.
