Well put Shakou. Every organism finds it's niche, an environment where it is able to adapt, thrive, reproduce and pass on it's genes. The niche with humans has been advantageous to dogs and has allowed them to evolve. I think comparing intelligence is almost beside the point. Of course different animals are going to vary in their talents.
"If you love wealth better than liberty, the tranquility of servitude better than the animating contest of freedom, go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains set lightly upon you and may posterity forget that ye were our countrymen." -- Samuel Adams 1776
"When the people fear their government, there is tyranny; when the government fears the people, there is liberty."
