The best grain-free dog foods typically contain more protein than those made with grain.
But many are made with grain-substitutes that can upset the nutrient balance of the finished food. That’s because the 2 most common ingredients used to replace the corn, rice and other cereal grains found in other dog foods include…
- Potatoes
- Legumes (peas, chickpeas, lentils, soybeans, etc.)
Although both are suitable grain substitutes… legumes are also rich in protein… which is a good thing.
Yet unlike meat-based protein… plant protein can be deficient in certain essential amino acids.
Which is why we recommend the 10 grain-free foods below… where meat remains the dominant source of protein… in each formula.
