My 13 week old German Shepard puppy will not eat her kibble. I've taken her to the vet and she is healthy. I have tried several brands of kibble including what she was fed by the breeder I am really getting worried. I have tried wetting her food, putting a tablespoon of wet and even chicken broth and nothing seems to work. I am giving her nutrical and wet food but I know kibble is better for her. Does anyone have any ideas? Thanks
