Sometimes she does if I don't stop her in time. I have 5 dogs so I'm pretty conscientious about barking unnecessarily. She barks at people she doesn't know when they come in the house & it can take a awhile before she settles down. Usually if they start playing with her she'll stop. And yes she's shy with people she doesn't know, she actually is a biter if someone just goes to pet her or pick her up. She has an orange caution sticker on her medical records at the vets.
