Of course, this brings up he question of "which species is truly intelligent". Humans define intelligence as the kinds of thinking that we are best at (we write novels about murder, we create reality TV shows, we argue endlessly about our political systems...).
But DOGS, well ummm.... no genocide, no child sexual abuse, no corporate greed, no fashion statements, no wars......
.....lots of play, unconditional love, honest emotions, simple living, desire to avoid conflict.....
What is intelligence, complex thought, moral ethics ?? Maybe they're a whole lot smarter than we think they are, they just don't need to prove it all the time.
Just speculating....
