Dogs in Society: The Versatile and Intelligent Companions for Work and Play"

[Another's Eyes]

Dogs in society are not only used as companion animals, but as working animals...helping the blind/disabled, searching for injured/dead, drug sniffing, etc. I've always thought dogs were very intelligent, but after reading the following article it makes me wonder.

I've always thought dogs were very intelligent,

Intelligent compared to what?
Does failing that test make them any less intelligent? (perhaps compared to a human, but how about compared to the rest of the animal kingdom?)
How often does finding food-on-a-string-in-a-box come up in their evolutionary history?

(from the link)
Many of the dogs eventually figured out what to do, but that ultimate success was more a matter of learning, not insight. But in the end, does it matter?

In some cases, could "learning" be more intelligent than "insight"? (e.g., if insight=instinct)
