Dogs are a function of their upbringing and tend towards affectionate behavior towards humans. If socialized they will think of people outside their family as sources of attention instead of intruders. Pits aren’t different. 30-50 people die to dogs out of 338M people. By contrast over 300 die in bathtubs and almost 400k die from heart disease.
You would be safer slip proofing your bathroom or skipping that greasy burger rather than worrying about rover eating you.
