Thanks so much for the advice everyone! It's good to know that she's just being a "normal" puppy. I have read that pugs are very eager for lots of love and do get sad/upset when they think they have displeased and looking them in the eyes when scolding works - it's great to hear that it does work from someone who has a pug I have to say that she is a great puppy and so much fun. I really love being a dog owner!
