I believe most of us dog owners knew intuitively that 5,000 years had to be wrong.
It's like knowing, intuitively that man had language, tools, shelter etc. more that 5,000 years.
It's arguable that dogs enabled man to truly civilize and subdue the planet.
Before them we had no eyes, ears or noses. We were too slow.
With them we became the Alpha Predator and were no longer prey to any beast.
A fundamental transition point in human development.
Oh, and fundamental to canine development as well. It was and has been a synergistic association.
Dogs got food, warmth and protection too.
And music.
And BACON! :)
