Dogs, stupid. DUH.
ahem. its more about diet then anything, really: look at what we eat, and then look at the smarter dog owners and what they feed their dogs. 4 food groups, with decent variety.
Plus, my dog will one day play video games with me using his specially built ps3 controller harness and the ULTIMATE WINGMAN WILL BE BORN!!!
seriously, if my dog can figure out how to open lever style tupperware which is beyond certain humans, soon they will be like author Dean Koontz's dogs, a perfect companion species for mankind. After all, the negative things humans desire almost don't intersect with those of dogs, but we most certainly want the same positive things dogs want.
