Definitely read some books, puppies playbite and thats a fact even though they look cute and cuddly, they can be an absolute nightmare. Pinching, wacking him on the nose with a newspaper are not going to work, I had the stupid advice to pick mine up by he scruff of her neck and shake her like a ragdoll
I'm a sensible person and knew this advice was rubbish even though the person had done it to their dog. Raising a puppy involves common sense, please just think about what you are doing. I never hit my babies or shook them so why would the crap advice to pinch a puppy or hit it on the nose make sense to a normal person.
Your puppy is not trying to dominate, it is playing and thats what puppies do. You need to teach your puppy what is acceptable and believe me it can take months and months, there is no quick fix after 2 weeks. Mine stopped playbiting and chasing my son altogether at about 6 months old and that is with a lot of work and training constantly for it to eventually sink in that he wasn't a plaything for her.
Don't be under the impression that you are going to learn all this at puppy classes either from my experience and not sure what boundaries you are expecting to learn at a puppy training class.
BTW how old is your daughter? If its that much of an problem at the moment with your puppy biting your daughter then commons sense says to limit this, theres no way your daugher should be subjected to a puppy biting her feet especially if the puppy is biting hard, if the puppy isn't responding to the ignoring then seperate them. Why let the puppy bite your daughter - yes she was brave but she shouldn't have to deal with that if she is really young. They need to mix but not when the puppy is biting like that.
