I wouldn't say they are stupid.. most labs are smarter than their owners lol. They are VERY smart though and basically can pick up anything. They can hunt, do search and rescue, be service dogs, therapy dogs, K9s for Police K9-Units, dock diving, agility, etc.

I agree any breed can have less-than intellegent dogs though. I think Labrador Retrievers are one of the smartest dog breeds out there. There are a lot of untrained dogs in shelters and people would say they are stupid, but they really aren't. I have heard that the worst-behaved dogs are usually the smartest and that usually is true. Take Marley from Marley and Me for example.

There are some dogs I have ran across that just don't get things in the shelter, it's not their fault. Dogs can be slow just like people but there's nothing wrong with it. We have Siete (See-et-A) a lab at the shelter. I love her so much and wish I could bring her home to work with her, she needs some manners. She is only 9 months old though, but very goofy and loving, VERY smart and has a lot of potential to do anything that someone wants her to do.

Dogs that don't get things aren't stupid, it just makes them special and unique. Our dog, Rudy is not that smart, but I wouldn't call him stupid if that makes sense. He is sure special though.
