So the "over 200 professional dog obedience judges" couldn't tell the difference between a smart dog and and intelligent dog. No wonder there are those that don't agree with it. :)
I smart dog can learn to sit quickly when trained....and intelligent dog learns that biting a porcupine is not a good thing and doesn't do it again.
I have had many dogs that I tried to teach fetch too....the intelligent ones do it once, then look at you like your nuts when to throw it away again. :)
