How much biting and chewing is normal puppy behavior?

A lot. Let's face it. They are going to bite and chew a lot. Some breeds and some dogs do it more than others and that's fine, but you've got to think about part of it is they're teething. We all know that babies teethe and chew a lot and drool, and their gums hurt and that kind of thing. Puppies do the same thing. They do it a lot more rapidly. The average dog will start to lose teeth (and, therefore, start to grow their new permanent teeth) as early as about four months. And usually by about six to maybe seven at the latest, all their permanent teeth are in.
You've got to think about this in reference to the chewing. They're not doing it just to be disruptive. They might do it because they're bored, but they're probably doing it because their teeth hurt and it feels good to chew on those things. So they're all going to do it to some degree. You just have to prepare accordingly for it and give them the right chew toys and things like that, which we'll cover in a second.

Puppies love to chew. That's why they make chew toys. We talk a lot about how your hand becomes a chew toy, and that's not ideal. Biting and playing are pretty normal, but some puppies can become a little too aggressive with it. So if you're feeling like they are doing a little too much growling or are forceful with their biting, and it's not just whenever they are excited or playful, reach out to us. It may not be quite so normal. And we might need to try and correct it.
