Second smartest breed, according to Intelligence of Dogs, though I have issues with that book, it’s fairly accurate at the extremes.
All of my guys and gals have been incredibly smart, and incredibly happy. Course, they’re well taken care of.
The current one is white, and you can really watch his facial expressions, which was much harder with the previous black ones.
So far, he can open sliding and swinging doors, the doorknobs just slow him down. He does watch TV, and reacts in ways that show he is following the plotline… as he sees it.
As a bit about self-image and sentience, as mentioned in an earlier thread, he almost killed the TV, from charging it, the first time he saw Westminster, and his father’s brother from the same mother and father but a different litter showed up.
Contrawise, the most neurotic dog I’ve ever known was on the far end of the spectrum. Twas an Afghan Hound. Named Jessica, after the redhead on Soap.
Dumb as half a brick, and nervous as a cat in a room full of rocking chairs.
However, I’ve found, having been involved in dog shows, that both intelligence and neuroses are breed-related tendencies.
Goldens tend not to be too smart, but incredibly happy, for example. Well known for it. Very well adjusted dogs.
So, while breed X may be known for being smart and neurotic, breed Y may be known for being smart and happy.
However, individuals within these breeds may be neither smart nor happy.
In short, dogs are people.
You got the jocks, you got the sensitive artists, you got the soldiers and you got the thugs. You got the salt of the earth, and you got the freak show.
Personally, I vote with John Steinbeck.
