Kidney Health Nutrition
Supporting kidney function through thoughtful nutrition
Kidney disease is one of the most common conditions affecting senior dogs. Proper nutrition plays a crucial role in managing kidney disease and supporting remaining kidney function. A thoughtfully designed diet can help reduce the workload on the kidneys while providing essential nutrients.
Understanding Kidney Function
Filter Waste
Kidneys remove metabolic waste products from the blood, including urea and creatinine
Maintain Balance
Regulate electrolytes, blood pressure, and acid-base balance in the body
Produce Hormones
Create hormones that regulate blood pressure and red blood cell production
Kidney-Friendly Dietary Principles
Moderate, High-Quality Protein
Use highly digestible proteins to minimize waste production. Quality over quantity is key.
Best sources: Eggs, fish, lean poultry, small amounts of lean beef
Reduced Phosphorus
High phosphorus can accelerate kidney damage. Limit phosphorus-rich foods.
Avoid: Organ meats, dairy, bone meal, whole grains in large amounts
Controlled Sodium
Moderate sodium intake helps manage blood pressure and reduce kidney workload.
Avoid: Processed meats, cheese, high-sodium treats
Omega-3 Fatty Acids
Anti-inflammatory properties help protect kidney tissue and reduce progression.
Sources: Fish oil, sardines, salmon
Increased Hydration
Moisture is critical. Fresh food provides natural hydration.
Add: Bone broth, goat's milk, additional water to meals
Kidney-Supportive Meal Components
Recommended Proteins
- Eggs (highly bioavailable, low phosphorus)
- White fish (cod, tilapia)
- Chicken breast (skinless, lean)
- Turkey (lean, ground or breast)
- Rabbit (novel protein, lean)
Beneficial Vegetables
- Green beans (low phosphorus, filling)
- Cauliflower (vitamin C, low phosphorus)
- Bell peppers (antioxidants, low protein)
- Cabbage (fiber, low calorie)
- Cucumber (hydrating, low nutrient density)
Foods to Limit or Avoid
❌ Organ Meats
Liver, kidney, and other organs are very high in phosphorus
❌ Dairy Products
Cheese, milk, and yogurt contain high phosphorus levels
❌ Processed Meats & Treats
High sodium content can worsen kidney function and increase blood pressure
❌ Whole Grains in Large Amounts
Brown rice, whole wheat, and oats contain more phosphorus than white rice
Important: Work with a Professional
Kidney disease management requires careful monitoring and individualized nutrition plans. Bloodwork values (BUN, creatinine, phosphorus, potassium) must guide dietary adjustments. Always work with a veterinary nutritionist when managing kidney disease.
