Your Guide to Renal Diets for Dogs With Kidney Disease
When Should I Feed My Dog a Renal Diet?
Your veterinarian will move your dog onto a renal diet as soon as theyve been diagnosed with CKD. But the diet they recommend will vary based on the stage of kidney deterioration, which progresses from
IRIS Stage 1 to 4.
What Types of Renal Diets Are There?
Once your dog reaches IRIS Stage 2 CKD, phosphorus restriction becomes necessary and so a diet like Royal Canin Renal Supportmay be suggested. As well as being low in protein and phosphorus, it has a high energy density to help maintain weight.
The build-up of waste products in a dogs bloodstream may begin to affect their appetite around stage 2 and many dogs will need extra encouragement to eat. Renal diets are designed to be extremely palatable for this reason, but some diets like Royal Canins go further by allowing you to mix aromas, shapes, sizes, and textures, as well as wet and dry options, to create a variety of enticing flavors.You can also encourage eating by gently warming wet food and adding warm water to dry diets. Because dogs with CKD have an increased risk of dehydration, always ensure they have access to lots of fresh water.If your dog has additional dietary requirements, due to food sensitivity or joint pain, there are different versions of renal dog food availablethat combine the various benefits into one carefully formulated diet.In the final stages of CKD, a veterinarian may use a liquid diet if specific types of feeding tubes are placed.Nutrition plays a major role in the management of CKD and can make a considerable impact on the quality of life of a dog. If you have questions about renal diets or CKD, speak to your veterinarian.

Renal Diet for Dogs: A Guide on Feeding
Chronic kidney disease in dogs is a progressive condition with the prevalence of 25% of dogs from veterinary clinics, with 9-16% mortality rate.
Senior geriatric dogs and some breeds are more likely to suffer from this condition.
Fortunately, early detection and dietary switch to a renal diet for dogs was shown in studies to significantly improve CKD condition.
What is Renal Disease in Dogs?
Canine renal disease, or chronic kidney disease in dogs, is when a dog's kidneys begin to malfunction, eventually losing the ability to remove waste and balance fluids in the dog's body.
In severe cases, this condition causes a complete loss of renal function, resulting in kidney failure and eventually death.
In early stages of kidney disease, it may cause metabolic acidosis, as well as prevention of absorption of water, leading to excessive thirst, increased urination, and nutrient loss.
In moderate cases, decreased blood cell production can lead to anemia and hypertension can occur affecting cardiovascular health.
As the disease progresses over time, bone health may be impaired in the dog, leading to bone pain and an increased risk of fractures.
Ultimately, uremic crisis, the inability of kidneys to eliminate waste products from the dog's body out of the blood leading to fatal blood poisoning, may occur.
For dogs who have been diagnosed with chronic renal disease, nutrition and vet-approved renal diet for dogs is a crucial part of the treatment plan.
Although canine kidney disease is often degenerative, dietary therapy will slow the progression of the disease and prevent further complications, such as complete kidney failure and potential death.
The Renal Diet for Dogs Guide
Therapeutic Dietary Support
There is strongresearch that supports using nutritional adjustments as a tool to combat the progression of renal disease in dogs.
Specific diets for dogs with renal disease and kidney failure were shown to maintain or improve nutrient absorption, delay the onset of uremia, slow disease progression or development of other complications, and extend the expected lifetime.
A veterinarian should be your first point of contact in helping you design a safe and appropriate renal diet for dogs with this condition.
You will have the choice of either switching to other commercial dog foods, prescription foods, homemade dog food diet, or a combination of both.
1. Balanced Level of Phosphate
All renal diets for dogs should contain carefully balanced levels of phosphate.
Phosphorus is an important mineral that is essential for cell structure, energy and bone health.
Low levels are associated with adverse health outcomes and malnutrition.
Although it is an essential part of the diet, balance is key, particularly when it comes to dogs with renaldisease.
As this mineral is metabolized by the kidneys, excessive quantities can place strain on the system due to reduced ability to metabolize the mineral.
Eventually, poorly balanced diet may lead to adverse effects such as weakening of the bones and calcification of body tissues, including the kidneys.
Specific dog kidney health diets contain the optimum level of phosphate and often dietary additives that bind phosphate, allowing it to be excreted through the gastrointestinal system instead of the urinary system.
2. Reduced Levels of Salt
When feeding a dog a renal diet, salt is one of the mostimportant considerations.
Animal studies have shownhow increased levels of salt in the diet to increase the protein excreted in the urine and markedly increase kidney function deterioration.
Similar studies have shown how the reduction of salt intake in dog's diet with kidney problems will slow down the rate of progression of the disease.
The bottom line is to decrease the amount of salt, but not necessarily eliminate it.
3. Low(er) Quantities of High-Quality Protein
Same as with salt, you'll need to reduce the amount of protein in the dog's diet. For this reason, most kidney-friendly options are often labeled as low protein dog foods.
Protein is a vital part of the canines overall nutrition which provides daily energy, promotes healing and maintenance of all tissues and cells in the dog's body.
However, protein breakdown also leads to toxic waste products in the bloodstream that requires processing by the kidneys for excretion through the urine.
Providing a diet that contains low levels of high-quality protein means a reduced amount of waste for the kidneys to process while the pets energy requirements are met.
4. Enhanced Levels of Omega-3 Fatty Acids
Omega-3 and fish oil provide many benefits to dogs, one of which is kidney support.
The supplementation of omega-3 polyunsaturated fatty acids has been suggested by vets because studies have shownits protective qualities and ability to slow the progression of renal disease in dogs.
Omega-3s are also known to promote blood filtering and support kidney function.
Several supplements containing high levels of omega-3s, particularly fish oil for dogs, have been observed to have a significantly positive impact in this area.
As pets who suffer from renal disease are often geriatric animals, they commonly present with other age-related conditions such as canine arthritis and joint pain.
Omega-3 fatty acids have further benefits for these pets as they have been clinically provento reduce pain and inflammation in dogs suffering from arthritis and reduce the need for analgesia.
5. Replacement of Vitamins
A healthy balance of vitamins and minerals may also help with the disease. These can be administered to dogs either via foods or through vitamin supplements.
As kidney disease causes increased urination, dogs often excrete excessive amounts of water-soluble vitamins which ultimately leads to depletion of essential nutrients.
As a result, this depletion can lead to malnutrition and side effects such as anorexia.
Therefore, it is absolutelyvital that these vitamins are replaced.
Ideally, you should do this through diet but supplementation may also work (although there's little evidence).
Specifically designed dog renal diets provide an optimum balance of B Vitamins and Vitamin C, as well as other essential vitamins and minerals for dogs with kidney problems.
Hydration for Dogs with Kidney Problems
Hydration is considered an essential objective in the management of renal disease in dogs.
Kidney disease causes canines to be unable to concentrate the urine.
This means that although you may notice your pet drinking more water and liquids, your dog is actually unable to compensate, which eventually causes dehydration.
Providing your pet with a sufficient amount of liquids reduces clinical signs such as lethargy and weakness, and is also seen to have long-term beneficial effects on renal function.
For this reason, many pet owners choose canned dog food that contains high water content than regular dry dog food brands.
However, it's important to pick the right type of wet dog food that will also factor in other aspects related to dogs with kidney problems.
How to Switch a Dog to a Renal Disease Diet
Loss of appetite is common in pets who are suffering from renal disease, and getting your dog to eat again can be a challenge.
However, as malnutrition in dogs can cause further complications, it is vital that you carefully monitor and encourage proper nutritionand feeding schedule in your pet.
Reduced appetite can often be a symptom of this condition. Taking this into account, dog renal diets are designed to be highly palatable to encourage nutrition in order to maintain healthy weight and energy levels.
Often, a learned food aversion will occur if a pet feels frightened, unwell or is force fed a new commercial dog food diet, or even a homemade dog food recipe. Thus, try to avoid any bad associations with the food such as simultaneously administering medication.
To encourage eating in dogs, attempt to create a comforting environment for your pet when offering his new dog food diet or homemade recipe. The ideal time to try a new diet is in a familiar home environment, rather than during hospitalization.
Introduce the new diet to your dog very slowly, gradually mixing the new food with the old, and continue increasing the kidney diet daily until it is the only one remaining.
If your pet refuses the new diet, consider another type of renal diet. It is essential that dogs with renal disease continue to eat. It is best to change to another therapeutic diet your pet finds more palatable prior to weight loss and muscle breakdown occurring.
Best Dog Food for Renal Disease in Dogs
Nutrition has long been considered of great value and genuine efficacy for the management of kidney disease in dogs. If your pet has been diagnosed with chronic kidney disease and your vet recommended a renal diet for dogs, other than homemade recipes, there are a range of quality, therapeutic diets for purchase.
Before you pick any commercial dog food brand, you must always consult with your vet.
Hill's Prescription Diet k/d Renal Health
This kidney disease dog food is available in dry and wet formulas.It contains small doses of high-quality protein and low levels of sodium.
Hill's Science is the oft-recommended dog food by veterinarians for pets with specific health problems, including kidney disease.
Low in protein and specifically adjusted to tax the dog's kidneys the least, the Hills R/D dog food also contains high levels of antioxidants, which aim to neutralize free radicals in order to slow the disease progression.
Purina Veterinary Diets Canine NF Kidney Function
Unfortunately, this canine renal disease dog food is only available in kibble form only, but it's a similar although less effective and less recommended option by vets (it is cheaper, however).
Purina Veterinary Diets Canine Kidney Function formula contains a nitrogen trap fiber system that aims to reduce nitrogenous waste the key waste product following protein breakdown that causes renal workload.
This system allows the diet to contain moderate levels of good quality protein.
ROYAL CANIN Canine Renal Support
This kidney disease dog food is available in dry formula. It contains low levels of phosphorus and low levels of high quality protein, to reduce renal workload.
Royal Canine Canine Renal Support formula also has a good amount of omega-3's most important parts, EPA and DHA, that help with regulation inflammation in the dog's body.
Again, before choosing any of these diets, please consult with your veterinarian.
I also recommend you read the reviews of these dog foods for renal support to see how other pet owners found them and what their vets told them about these dog food brands.
