What to watch for

Wheat flour Low risk
Ground wheat, common in treats and biscuits as a binder. Wheat is a known allergen for some dogs.
Corn Low risk
Cooked corn is a digestible source of energy and some protein. It is often criticised but is not a common allergen; its main risk is mould toxins (aflatoxin) when quality control is poor.
Fish meal Low risk
Rendered fish. A concentrated protein, but 'fish' does not name the species, so it is harder to avoid if your dog reacts to a particular fish.
Natural flavor Low risk
Flavoring from natural sources. Normally safe, but the term can hide which animal or plant it came from, which matters for allergies.
Salt Low risk
Salt supplies sodium and chloride, which dogs need. Pet foods use small amounts; high salt is mainly a concern for dogs with heart or kidney disease.
Copper sulfate Low risk
A source of copper, an essential trace mineral. Some breeds accumulate copper in the liver, and vets have raised concern that some dog foods supply more than dogs need.
