Hi puppypiles-
Yes Corgis are technically suppose to be a fed a large breed puppy formula because they are often plagued with the same growth disorders large breeds get.
For puppies the best thing to do is use a commercially available dry food that is suited for the growth of large breed puppies and then once he/she is an adult switch to a raw diet. You also can talk to the breeder or multiple breeders and see what they recommend. Make sure you are talking to breeders that know what they are doing though.
