Notes and tips

• “Complete and balanced” statements on the label indicate a product formulated for all nutritional needs for a specified life stage (puppy/growth or adult/maintenance). Look for compliance statements from authorities relevant to your region (e.g., AAFCO in the U.S., FEDIAF in Europe) or wording used locally.
• Many brands offer separate puppy and adult formulas (different nutrient profiles). Some also offer formulas for specific breeds, sizes, or health conditions.
• If you want a shorter list filtered by region (Australia), diet type (dry, wet, raw, grain‑free, limited ingredient), price range, or veterinary diets, I can provide a tailored list.
