You need to do some reading on this, and also talk to your breeder and vet.

Different breeds have different issues—and certainly not all dog foods are the same.

We always look at the ingredients and try to keep cereal content to an absolute minimum. Also we try to keep the fat content below 5% (not easy) and the protein content as high as possible.

Cereal and peanut butter cookies, doggie granola bars etc etc and similar nonsense is really not doing your dog a favour.
