It very well could be that she does have hair poking out of her ears and its itching her. I know you said the vet looked at her ears, and they don't smell, but did the vet do a ear swab, to see if she may have mites? Just a thought.
With her being a pup, I think all pups go through the exploring of having to know what everything is, so they will chew on everything! LOL
My furkids love apples and raw baby carrots too!!!
I had a pup who did that too, always had her tongue sticking out, when she sat there, now that she is older, every once in a while I will see it sticking out! LOL!!
Sounds like you are really enjoying your baby!
