 In the tv series, Dexter also takes a detour in his code of only killing murderers in order to dispose of a pedophile who is stalking Astor.Animals do not like Dexter, which can cause noise problems when Dexter stalks a victim with pets.He is quoted as having once had a dog that barked and growled at Dexter until he was forced to get rid of it, and a turtle, which hid in it's shell until it died of starvation rather than have to deal with Dexter.
