Yelping in a shockingly stern tone, while turning away, ignoring for a few seconds. This is what a mother dog would do to teach its pup. We raised 2 lab/retriever mixes to have very gentle mouths. It was shocking how sharp those little puppy teeth are and really important to curb it from the beginning. It sounds like you've done the research. Freeze kongs of peanut butter, nonfat yogurt, kibble and your puppy can chew on these instead.

Ian Dunbar's books and videos are great!! They're free online.

If the puppy bites or chews on you, immediately say no, stop playing, petting etc, stand up and walk away. Ignore the puppy for a few minutes. It will take some repetition, but the puppy will learn.

We are getting a puppy and I’ve been researching this in anticipation. This seems to be an area where there are varied responses to how to deal with this. In addition to giving the puppy plenty of exercise and making sure she has plenty of chew outlets, what is the best direct human response? For example, I’ve seen pull your hands away, out them under your arm pits and turn around, pull hand away and yip as though in pain, and hold dog collar on side so she can’t bite you and give it a slight tug and then praise lavishly when not biting (this one seems like an outlier). Interested in what’s worked best and any related training videos or podcasts. Thanks!
