They also play a vital role in getting rid of toxins and waste from the body.

Let’s start with the common symptoms and proceed with how you can buy the best dog foods for kidney disease.
Highlighting the Common Symptoms of Renal Failure
Problems associated with kidney diseases can be difficult for your dog. The symptoms can directly affect their quality of life. However, there is a difference between acute and chronic renal issues. Let’s look at each of them in detail.
As the name suggests, acute renal failure has a sudden onset. It can result from things such as poisoning and ingestion of forbidden foods like raisins or grapes.
More reasons that could cause acute renal failure include infection, dehydration, trauma, or certain medication. As a pet parent, you must consult your veterinarian immediately if you notice the following symptoms:
- Change in urination or more frequent urination
- Change in water consumption
- Increased lethargy
- Lack of appetite
- Difficulty in coordination
- Change in behavior
The overall result of the diagnosis may vary based on how advanced the disease is. Some dogs in the early stages may make complete recovery with a changed diet and proper treatment, while others may progress it into chronic renal failure. Therefore, it is important to immediately seek professional assistance as soon as you detect the symptoms.
Chronic renal failure is more common in older dogs, but direct poisoning or certain congenital defects can affect the younger ones too. Chronic renal disease often advances at a slow pace, making it difficult to see through the symptoms.
Even though it’s slow, it is still a progressive disease and will only worsen with time if not managed properly. If your dog breed is prone to the disease, it is best to keep an eye for these symptoms:
- Drastic weight loss
- Change in urination
- Change in water consumption
- Lack of coordination
- Pale gums
- Abdominal pain
We advise that you take your dog for a full-body examination if you detect these symptoms.
Kidney Disease and Other Health Complications
It’s hard to come to terms with the problems your dog has to go through. Kidney failure itself is a painful condition, and there could be further health complications that could make it more challenging. It is, however, important to remember that these health problems may appear together with kidney issues but not necessarily.
Congestive Heart Failure
Kidney and heart problems are often related; this is called Cardiorenal Syndrome. It means that kidney failure can cause heart conditions and vice versa.
Anemia can result from kidney failure and has symptoms such as depression, weakness, rapid breathing, apathy, weight loss, fatigue, or heart rate. Treatment for kidney failure also usually include hormone therapy and medications to reduce the symptoms of anemia.
Chronic kidney failure is often associated with bacteria entering the bloodstream; it can also cause damage to the heart and liver over time. It is one of the major reasons why kidney problems are often accompanied by liver failure as well.
Chronic kidney failure can also cause acidosis due to the diminished ability of the kidney to filter out blood acidity and toxicity. Treating acidosis can help slow down the advancement of renal failure.
The bean-shaped organs are responsible for maintaining blood pressure. If the kidneys stop working properly, it can lead to hypertension. If left untreated, the symptoms can damage the brain, blood vessels, heart, and eyes.
The Best Dog Food for Kidney Disease – Everything You Need to Know
Arm yourself with the following information before heading out to choose the best food for dogs battling kidney disease.
Wet/Canned Food Formulation
The extra moisture in wet/canned food formulation is beneficial for dogs with kidney disease. Water is essential for the successful filtration of toxins from the bloodstream. Transitioning to a wet food diet can be difficult for dogs who have eaten kibble are their lives. To help your dog with the transition, we recommend combining a wet food diet with dry food to keep your dog hydrated. Also, don’t forget to provide your dog with plenty of fresh water along with food.
Low Protein Level
Kidneys work to remove the toxins produced from protein breakdown. When kidneys are not functioning well, this can lead to a buildup of these toxins and put stress on the organ. Therefore, it is crucial to offer your dog food with reduced levels of protein.
Also, limited protein content should come from high-quality sources. Improved quality guarantee fewer toxic byproducts and doesn’t strain the kidneys as much.
Phosphorus is considered as an important mineral to maintain your dog’s teeth and bones, but if your pooch has kidney problems, high levels of phosphorus can be poisonous.
The excess level of the mineral is taken care of by the kidneys, but when the kidneys are failing, the excess amount continues to build up. Extra phosphorus can cause vitamin D deficiency and loss of bone density.
Increased Levels of B-Vitamins
Even though there are no direct benefits from Vitamin B to the kidneys, it can help with the symptoms. It is best to choose a diet with high levels of B-vitamins. You can also add it from the tap by dissolving it in water for increased water intake.
Enriched with Omega-3 Fatty Acids
Omega-3 fatty acids are not only great for your dog’s fur but also reduce inflammation, which reduces pressure in the kidneys. It also helps remove toxins from the bloodstream.
Powerful antioxidants such as vitamins C and E are great for preventing cell damage and combat free radicals. These antioxidants play an important role in contributing to the overall health of your pooch and slow down the progression of failing kidneys.
Food options that contain cheap ingredients, artificial flavors, preservatives, added color, and other unnatural ingredients are bad for a dog with failing kidneys. Organic food from natural sources also ensures a renal-supportive diet has good flavor.
Reduced Sodium Levels
High levels of sodium can affect blood pressure and be harmful to the kidneys. Controlling the sodium level through food will not only help your pooch’s kidney but also prevent other life-threatening diseases like heart problems.
What Not to Feed Your Dog with Kidney Disease
We recommend a specialized diet designed for renal care for dogs diagnosed with kidney disease. However, you can stick to a normal, low-protein formula if the condition is in the early stages. The key is to avoid certain ingredients, and that would include:
- Excess protein
- Formulas rich in phosphorus
- Food rich in sodium
- Fruits and vegetables such as onions, garlic, grapes, and raisins
- Avoid wheat gluten
Tips on Switching Your Dog to a Renal-Supportive Diet for
If kidney disease is discovered at an early stage, it may not be necessary to place your dog on a restricted diet. However, certain considerations need to be taken into account. For starters, switch to formulas made with limited ingredients.
Consult your vet to find out if it is the right time to change to a specified renal diet. Make sure the transition is very slow, as most options with restricted protein levels may not be as tasty for your pup. Rotating the formula and gradually adding the new food to his meals will encourage him to eat.
In case you are having a hard time with your pooch, consider seasoning the food with natural additives or delicious wet food options to make it more enticing. Just make sure you do not counter the benefits of special renal diets by adding foods high in sodium or other harmful ingredients.
Is it important that I change the diet of my dog suffering from kidney disease?
Yes, it is important to switch to a diet that supports kidney care. The food you feed needs to provide proper nutrition, absent the ingredients that can worsen the condition. Changing your dog’s diet not only supports better organ function but helps control symptoms and prevent other health issues that are associated with kidney problems. Tailoring the formula is crucial for your dog’s health and long life.
Can I give homemade dog treats to my dog with kidney disease?
Just because your dog has been diagnosed with kidney disease doesn’t mean you should stop rewarding or treating your dog. Avoid treats that contain high levels of phosphorus, protein, and sodium, so don’t feed your dog things like cheese, dry meat, or bread. The best treats are natural vegetables and fruits but avoid grapes, raisins, garlic, and onion.
What do I feed my pooch who refuses to eat?
Not every kidney-supportive diet available in the market offers great flavor. Picky eaters might give you a very hard time switching to a specific healthy diet. While you can always try home-cooked meals, the products I have reviewed in this article are savory and palatable and entice your dog to eat.

Kidney disease is more common in older dogs and can affect up to 4% of dogs. However, even younger dogs are prone to the disease if they live in an unhealthy environment, and bacteria enter their bloodstream through food.

What’s the best way to diagnose kidney disease in dogs?
Identifying the symptoms, in this case, is not enough. A vet may recommend urinalysis and a complete blood profile to conduct a proper diagnosis. Dogs with kidney disease may also have high blood pressure, abnormal electrolyte levels, and even anemia. Some vets may also recommend an ultrasound for accurate results.
What should I expect from my dog if he has kidney disease?
While you can ensure a long and comfortable life for your dog even with kidney disease, it can cause certain problems. In addition to changing your dog’s diet, you must also consider your pet’s lifestyle and water consumption. Also, you can expect different behavior and mood from them. Kidney disease can lead to poor appetite, which causes lethargy and constant tiredness. Maintain your pooch’s muscle mass and keep up with weight maintenance by adding food toppers on his regular food such as fish oils, tuna juice, and chicken stock.
What should I do to switch my dog’s food to a more renal-supportive diet?
The key is taking a gradual approach to switching your dog’s diet. To start with, mix only a bit of the new, renal-supportive food with the regular food your dog already loves. Increase gradually and let your dog take its time adjusting to the new diet. You can always add to the palatability of the new diet by adding delicious, healthy toppers.
How long would my dog live with kidney failure?
According to a study, the average life expectancy of a dog diagnosed with kidney failure can range between 112 to 326 days. However, as bleak as it may seem, the right diet and proper care can show the progression of the disease and your dog may live several years if the diagnosis and treatment are taken care of on time.
How can I improve my dog’s kidney function?
One of the best ways to control the progression of renal disease is to provide a diet that low in protein, sodium, calcium, and phosphorus. Eliminating the excess protein and minerals can stabilize your pooch’s system and improve kidney enzymes, leading to a longer, healthier life span.

Protein is a calorie-dense nutrient, and feeding too much of it can increase the workload on the kidney as well as the liver.
Should I take my dog for exercise if he has kidney disease?
In addition to giving a renal-care diet to your dog, exercise is great to improve general health, fitness, and overall quality of life. Also, it can reduce the risk of other diseases associated with kidney failure such as cardiovascular risk.
What are the possible conditions that could lead to kidney failure?
Acute kidney failure can result from an abrupt decline in the organ function that happens over time from ingesting toxins, certain medications, tainted foods, etc. Other conditions include urinary obstruction, infections, and decreased flow of blood or oxygen to the kidneys.
What foods should I avoid feeding my dog with kidney disease?
First of all, whatever diet you chose should be low in protein, sodium, and phosphorus. Also, avoid giving high protein treats to your dog, such as cheese, jerky treats, meat, pig ears, rawhides, etc. Similarly, treats with a high level of sodium can increase blood pressure and worsen kidney damage. If you are picking up a readymade meal, make sure you read the labels to be sure about what you are feeding your pooch.

Based on a study, the breeds most prone to kidney failure include:

Is wet food a better option for dogs with kidney problems?
Because of their moisture content, wet food options are preferable. But in addition to being low in protein content, some wet food diets may be limited when it comes to other essential nutrients. Therefore, it is best if you give your pooch a combination of both to keep up with their special dietary requirements.
While kidney disease is not reversible, with proper diet and management, your dog can live years past diagnosis.
If you suspect your dog is experiencing problems related to their kidneys, you should immediately consult with your veterinarian.
