Essential Nutritional Components
Macronutrient Requirements
| Nutrient | Dogs | Cats | Key Functions |
| Protein | 18-29% | 30-50% | Muscle maintenance, enzyme production |
| Fat | 10-16% | 15-20% | Energy, skin/coat health |
| Carbs | 30-50% | <20% | Fiber, energy (species-dependent) |
| Moisture | Varies | Critical | Organ function, digestion |
Based on AAFCO 2023 Nutrient Profiles
Pet Food Types Compared
Commercial Formulations
| Format | Advantages | Considerations |
| Dry Kibble | Dental benefits, cost-effective | Lower palatability, processing |
| Wet Food | Higher moisture, palatable | Shorter shelf life, cost |
| Raw Diet | Natural enzymes, high protein | Bacterial risks, unbalanced |
| Freeze-Dried | Nutrient retention, convenient | Rehydration needed, price |
Decoding Pet Food Labels
Ingredient Analysis

Guaranteed Analysis
- Minimum crude protein
- Minimum crude fat
- Maximum crude fiber
- Maximum moisture
Life Stage Nutrition
Puppy/Kitten Formulas
- Higher calories: 400-500 kcal/cup
- DHA enriched: Brain development
- Small kibble size: For deciduous teeth
Adult Maintenance
- Balanced macros
- Weight management options
- Breed-specific formulations
Senior Diets
