Generally there are some breeds that seem smarter than others.
However, I always find it slightly amusing to read the 'smartest dog list".
I think individuals vary greatly.
I also think trainability and cleverness, are all to oft confused.
Smart at what?
Herding?
Obedience?
Tricks?
Protection work?
Sneaky?
I have a friend with a Border Collie.
Great at herding & obedience etc.
But simply will never be able to do things my Dobes can, because its timid.
It wont jump off the high jetty to fetch a ball - too 'traumatic' lol.
Even though it knows how to swim.
Does that make it dumb?
No.
It just uses its brain differently to my dogs who seem to be able to cope with dangerous situations with ease.
I know plenty of smart dogs that are terrified of thunder?!?
Seriously.
Why?
It has never hurt them.
My dogs even enjoy going to the New Years fireworks each year!
(They would love to chase those Catherine wheels).
Not smarter - Just different intelligence.
One able to cope with pressure, stress or fearful situations without loosing concentration or focus.
One with a natural ability to herd, that mine could never match.
I had a Dalmatian who was a total failure at dog obedience!
(In comparison to my quick to learn Dobes).
However, he was a sneaky, calculating, thief.
His nick name was Hoodini.
He could escape any 'dog proof fence'. Yes he could climb vertically.
He would wait until all signs of humans were gone, before committing his 'crimes'.
Hopeless at basic obedience...
But intelligent?
Hell yes!
He would have come last on the 'clever dog list of skills'.
But he was smart in my mind - no doubt.

Stupid is as stupid does, springs to mind :P
Great question though.
PS - I am a complete math moron...
But the first time I jumped out of a plane (solo fyi, not tandum).
I loved it, stayed relaxed. Never got anxious.
Went through my drills (tongue pokes, signals, horizon to ground circle of awareness etc).
Landed on my mark - And got "Jumped her *** off" written by my instructor in my log book.
And went on to jump again.... and again!!
My highly intelligent mathematically inclined, Engineer friend - froze.
Brain turned to mush.
Failed to hard arch off the door.
So her instructor had to pull her shoot as began to spin (before she flicked them away as she was also solo).
So she never experienced freefall.
Didn't remember anything.
And never jumped again.
Not dumb.
Just different brain wiring to me.
