Is OK for my 8week old puppy jut to eat dried food

You should have him on a well fortified puppy chow, such as Iams or Science Diet which will provide him with a good head start into his adulthood. Meat is only a small concern right now and just meat Would not give him all he needs.

Don't forget a vet check and information on vaccinations he will need.

I would wait until the puppy was a few months older
