Your puppy’s desire to bite and mouth you as well as other people is motivated by their natural drives within them. In this chapter you will learn what motivates your pup to use their mouth, why they are using it and how to stop your puppy from biting and mouthing.
When you bring your new puppy home at 6-9 weeks and ween them from their siblings, you become their sibling. So, of course, they want to play with and engage you. And that is Great!! However, when they start to mouth you and keep playing and reinforcing their behavior, you have just taught them it is okay to put their mouth on you. They remember this and repeat the behavior, and it repeatedly works, empowering them. This is why the mouthing gets worse and begins to generalize into biting.
