Sorry this may be a little late.... but try taking a cloth wash rag or a small rag, and get it wet, splash it with chicken broth or beef broth, and freeze it. (before sticking it in the freezer, make sure it's in a good shape for the puppy to chew on it once it's frozen)
Give it to the pup and let her chew away!!
Also you can take a raw hide and soak it in water and let it get soft, then let her chew on it, when their teeth are comming in they like to chew on things that massage their gums, so something Sort of soft, so they can sink their teeth into it, will make them feel better!!
