Understanding dog nutrition
Omnivorous nature:
Unlike cats, dogs are omnivores and can digest both plant and animal matter. However, they still require high-quality animal protein as the foundation of a healthy diet. Their digestive systems are adapted to process a variety of foods, but quality protein remains essential for optimal health.
Essential nutrients:
Dogs require specific nutrients in their diet:
- Protein: High-quality animal protein for muscle maintenance
- Fats: Essential fatty acids for skin, coat, and brain health
- Carbohydrates: Energy source and fiber for digestive health
- Vitamins and minerals: Essential for various bodily functions
- Water: Critical for overall health and hydration
Life stage requirements:
Nutritional needs vary by life stage:
- Puppies: Higher protein, fat, and calories for growth
- Adults: Balanced nutrition for maintenance
- Seniors: Easily digestible proteins, joint support
