Top Grain-Free Dog Food Options (2026)
Expert analysis of the best grain-free formulas. Plus: should your dog go grain-free?
FDA Investigation Note
The FDA investigated a potential link between grain-free diets and DCM (heart disease) in dogs. While no definitive cause was found, consult your vet before switching to grain-free, especially for breeds prone to DCM (Golden Retrievers, Dobermans, etc.).
Who Should Feed Grain-Free?
Grain-free diets are beneficial for dogs with diagnosed grain allergies (rare, affecting less than 1% of dogs). Signs include:
- Chronic ear infections
- Excessive scratching/licking
- Digestive issues that improve without grains
Most dogs do NOT need grain-free food. Grains like rice and oatmeal are nutritious and easily digested by most dogs.
