May I ask.. is she biting or sort of chewing on people? The reason I ask is my cousin-in-law has Labs and says they are “mouthy”. That means, they like to put your hand in their mouth and sort of keep it there. We have a female Doberman that does the same thing... it isn’t aggressive. In fact, it is her playful/loving attempt to get your attention.
For the most part, “mouthy” is an apt description but those sharp puppy teeth make it painful at times. She has lots of toys, Kongs, and teething chew sticks but likes to work on shoes and people. She has not taken to the rawhide like our previous dog did. The previous dog, an Australian cattle dog, would work a rawhide to death in pretty short order.
