I have a dog that acts a lot like that, she's not dumb though she's just a bit stubborn. She took a long time to learn down, and she licks everything, stares a lot, I think it's a personality thing. She does have neurological problems (epilepsy) but I don't think that has anything to do with why she acts that way I agree with the person before me. Puppies are brats!
