i have a 7 week old puppy too, who just picked at her food, but now she eats the whole lot. i changed her diet to denes wet food, she didnt like that so shes now on burns pet nutrition. i got it from ebay at a great price. all puppies upto 12 weeks o0ld should be fed 4 meals a day, then from 12-16 weeks 3 meals a day, from 16-9 months on 2 meals a day. you can then choose whether to keep feeding 2 meals or just 1 meal a day at this point.
