Kidney Disease Diet Support for Dogs (CKD / Renal Diets)
Canine nutrition support for dogs with chronic kidney disease across the UK.
Kidney disease can feel overwhelming. Appetite changes, weight loss, nausea, and increased thirst are common and it’s hard to know what to feed when your dog suddenly becomes sensitive to foods they previously enjoyed.
The good news is that nutrition is one of the most effective, immediate ways to support a dog with CKD. A well-balanced renal diet can help reduce the workload on the kidneys, support stable blood values, maintain muscle, and improve your dog’s day-to-day comfort.
How Nutrition Supports Kidney Function
Dogs with CKD benefit from diets that are:
1.Moderate in high-quality protein
Not low protein. but the right amount, to maintain muscle without adding unnecessary renal stress.
2.Controlled in phosphorus
This is one of the most important factors. Excess dietary phosphorus contributes to blood phosphorous levels and can contribute to the progression of kidney disease. A tailored recipe keeps phosphorus safely within renal-appropriate ranges.
3.Balanced for calcium and essential fatty acids
A correct Ca:P ratio supports mineral balance. Essential fatty acids help reduce inflammation.
4.Gentle on digestion
Dogs with CKD often have nausea, reflux, or intermittent vomiting.
Hydrating foods, cooked diets, and simple textures make eating easier.
5.Supportive of hydration
Moist diets, broths and small frequent meals help maintain fluid balance.
Each dog is different, so all diets are adjusted based on stage of CKD, appetite, weight history, blood biochemistry, and individual tolerances.
When to Seek Nutritional Support
Your dog may benefit from a personalised plan if they have:
- A diagnosis from your vet for CKD
- Weight loss or muscle wastage
- Difficulty tolerating commercial renal foods
- Multiple intolerances alongside CKD (e.g. poultry, beef, eggs) or additional conditions
Or if you simply want guidance without the overwhelm.
