Kidney disease is a common issue in dogs, affecting around 10% of dogs over the age of 15. While the condition is irreversible, a special canine diet can help to manage symptoms, slow the progression of the disease, and improve a dog's quality of life. These diets are typically low in protein, phosphorus, and sodium, and high in omega-3 fatty acids, antioxidants, and other essential nutrients. The aim is to reduce the kidney's workload and provide adequate nutrition to maintain a stable body weight. Veterinary therapeutic diets, homemade recipes, and canned kidney support foods are all options to support dogs with kidney problems.

What You'll Learn
The importance of flavour and appetite
Maintaining a healthy appetite in dogs with kidney disease is essential to ensure they receive adequate nutrition. Kidney disease can cause a decrease in appetite, making it challenging to meet their nutritional needs. This loss of appetite is often due to the metabolic and physical changes associated with kidney disease, including nausea and vomiting. Thus, it is crucial to make their food as palatable as possible.
The flavour and taste of dog food play a significant role in encouraging consumption. Special diets for kidney problems should be carefully formulated to be highly palatable, with appealing flavours, aromas, and textures. This increases the likelihood of dogs eating the food and receiving the necessary nutrients.
Additionally, the diets should be calorie- and nutrient-dense, allowing dogs to obtain sufficient nutrition from smaller portions. This is particularly important for dogs with kidney disease, who may have reduced appetites and struggle to consume larger quantities of food.
The transition to a new diet should be gradual to avoid upsetting the dog's stomach and deterring them from eating. Mixing small amounts of new food with their old food and gradually increasing the proportion over several days can help them adjust to the new flavours and textures. This slow transition also gives their digestive system time to adapt, reducing the risk of food refusal.

Reducing phosphorus and protein intake
Protein is inherently high in phosphorus, which is why veterinarians recommend reducing protein intake. However, it is essential to provide dogs with proteins that are low in phosphorus. Plant-based sources of protein, such as egg whites, tend to be lower in phosphorus than animal-based sources. Additionally, certain cuts of poultry and wild duck are excellent low-phosphorus meat options.
It is worth noting that protein is essential for a dog's survival, and levels must be carefully balanced. While reducing protein intake can help alleviate clinical signs of uremia, a condition that occurs when waste products like creatinine and blood urea nitrogen build up in the bloodstream, it is not always necessary to restrict protein.
To ensure your dog receives adequate nutrition while managing their phosphorus and protein intake, it is crucial to consult a veterinarian or a canine nutritionist. They can help you choose an appropriate formulation or even recommend a veterinary nutritionist to provide recipes for homemade kidney-friendly meals.

The role of omega-3 fatty acids
Omega-3 fatty acids, including eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), are essential for supporting kidney function in dogs with chronic kidney disease (CKD). These fatty acids help to reduce inflammation in the kidneys and slow the progression of the disease.
Veterinary therapeutic diets for dogs with CKD typically include elevated levels of omega-3 fatty acids. These diets are designed to be palatable, as it is crucial for dogs with CKD to eat adequately and maintain a stable body weight and body condition. Omega-3 fatty acids can be added to a dog's diet through supplements or by including fish oils in their meals.
Additionally, omega-3 fatty acids can help reduce the production of inflammatory compounds that create oxidative stress on diseased kidneys. This, in turn, helps to preserve kidney function and improve the dog's overall quality of life.
It is important to note that while omega-3 fatty acids are beneficial for kidney health, they should be included as part of a well-balanced diet recommended by a veterinarian. The diet should be tailored to the individual needs of the dog, taking into account factors such as the stage of kidney deterioration and any other underlying health conditions.

The benefits of fresh food diets
Chronic kidney disease (CKD) is a common condition in dogs, affecting around 10% of dogs over the age of fifteen. While the condition is irreversible, a tailored nutrition plan can help increase your dog's quality of life and limit associated health issues.
- Fresh food diets can be hydrating for dogs with kidney problems. Dogs with kidney disease can get dehydrated easily, so moisture in their food is important. Fresh food diets can have up to 85% moisture, compared to kibble, which is usually about 10-15% moisture.
- Fresh food diets can be tailored to your dog's specific needs. Every dog is unique, and a homemade diet can be adapted to suit them. For example, a fresh food diet can incorporate high-quality protein sources that are lower in phosphorus, such as egg whites and certain cuts of poultry.
- Fresh food diets can be more digestible for dogs. Raw diets, in particular, are more easily digestible for most dogs.
- Fresh food diets can be palatable. It is important for dogs with CKD to eat adequately, and a fresh food diet can be made tasty to encourage your dog to eat.
- Fresh food diets can be nutrient-dense. Dogs with CKD need a special formula of nutrients to help them maintain their body and muscle condition. A fresh food diet can be adapted to be high in the nutrients that your dog needs, such as omega-3 fatty acids, antioxidants, and vitamins.
It is important to consult your veterinarian before making any dietary changes for your dog, to ensure the safety and appropriateness of the fresh food diet for their specific needs.

The impact of sodium and salt
Sodium homeostasis, or the maintenance of stable sodium levels, is crucial in dogs with chronic renal insufficiency. Studies have shown that dogs with this condition may experience prolonged sodium retention and a prolonged excretory cycle when given a sodium challenge, indicating a reduced ability to excrete sodium rapidly. This can lead to an expansion of the extracellular fluid volume and a disruption in volume homeostasis.
Additionally, the interaction of sodium with other nutrients, such as protein, phosphorus, and potassium, further complicates the understanding of its impact. For example, low-sodium diets are often associated with reduced protein intake, which can alleviate clinical signs of uremia, a condition characterized by the buildup of creatinine and blood urea nitrogen in the bloodstream. However, it is challenging to determine the independent effects of sodium due to the varying levels of protein, phosphorus, and caloric density in diets.
Veterinary therapeutic diets for kidney support often include moderate sodium restrictions, along with moderate protein and phosphorus restrictions, and elevated levels of omega-3 fatty acids and potassium. These diets are designed to be palatable, as it is crucial for dogs with kidney issues to eat adequately and maintain their body weight and condition.
In conclusion, while the impact of sodium and salt on canine kidney problems is multifaceted, it is generally believed that mild sodium restriction can be beneficial for dogs with kidney issues. However, it is important to work with a veterinarian to ensure a well-balanced diet that meets the specific needs of the dog, as individual variations may exist.

Frequently asked questions
A special diet can help increase a dog's quality of life and limit associated health issues. It can also slow the progression of Chronic Kidney Disease (CKD).
A canine kidney diet should be low in phosphorus and sodium but high in omega-3 fatty acids and other essential nutrients. It should also be calorie- and nutrient-dense.
Plant-based sources of protein are lower in phosphorus than animal-based sources. Egg whites and certain cuts of poultry are also good sources of low-phosphorus protein.
Transitioning to a new diet should be done very slowly. Start by mixing 5% of the new food with 95% of the old food for the first two days, then gradually increase the proportion of new food over the course of about two weeks.
