Dogs nuzzleing

Question
My dog is rubbing her head, nose into blankets, clothing and me.  She is wagging her tail and seems happy.  What is she doing?

Answer
She could be just loving you. Take her to the vet to make sure you're not dealing with allergies.  I honestly think she is just loving you the best that she can. It's her way of putting her scent on you, Much like a cat does when it rubs you.
Seems that you have a happy , loving dog.
