What to watch for
- 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.
What it does well

Meets an AAFCO nutrient profile. - High protein 35.6%
30% or more on a dry-matter basis. - Named meat first
