The real culprit here is almost certainly population growth, which has climbed steadily from 296 million Americans in 2005 to 333 million by 2023—more people means more dog owners, more dogs, and statistically more fatal incidents. Meanwhile, Amazon's revenue rocketed from roughly $8.5 billion to $575 billion over the same period, driven not by canine violence but by the wholesale transformation of how humans buy things online, which itself correlates with rising incomes, suburban sprawl, and the sheer proliferation of stuff. The third variable, in other words, is us: more of us, wanting more things, owning more dogs, all moving together through two decades of American life like passengers on a ship we didn't realize was accelerating.
