While chronic kidney disease certainly isn’t a “good” diagnosis for any dog, there are plenty of ways to manage the disease and keep Fido’s tail wagging for years to come.

Often, this includes switching to a food designed specifically for dogs with kidney issues. 

Below, we’ll explain what kidney disease is, share some signs that indicate your dog’s kidneys may be struggling, and discuss some of the treatment strategies including diet adjustment. We’ll also identify some of the best dog food for kidney disease options so your mutt can safely enjoy his munchies

It’s important to work with your vet if you suspect your dog is suffering from kidney issues.

Not only will you need your vet to help monitor and treat the problem, but you’ll also need your vet to provide a prescription or authorization to obtain a kidney-friendly food.

What Is Kidney Disease in Dogs?

Your dog’s kidneys operate as a filtration system and help keep his body in balance. This includes executing a whole range of tasks, but some of the most important include:

  • Filtering Waste from the Bloodstream — The kidneys work to remove waste from the bloodstream, and then dispose of these wastes via your dog’s urine. 
  • Maintaining Water and Mineral Concentration Levels — Kidneys help maintain a balance of salt and water in the body. For example, if your dog’s body fluids are currently too diluted, the kidneys may signal the body to excrete more urine. 
  • Controlling Blood Pressure — Kidneys partially maintain blood pressure by aiding in calcium metabolism, maintaining appropriate phosphorus levels, and adjusting the amount of water in the body.  
  • Manufacturing Some Hormones — The kidneys produce hormones that encourage red-blood-cell production which helps carry oxygen throughout the body. 

Kidney disease occurs in two different ways: acute kidney disease (or kidney failure) and chronic kidney disease.

Acute kidney failure usually occurs as a result of ingesting toxins like antifreeze (hence the importance of using pet-safe ice melts) or medications. This can cause an abrupt decline in kidney function.

Chronic kidney disease, on the other hand, develops slowly and presents itself more over time. It can be caused by a variety of genetic and environmental factors (more on this below). 

Both types of kidney disease warrant veterinary attention, but while chronic kidney disease will require long-term efforts to address, acute kidney disease is a medical emergency that can be fatal and requires immediate treatment. 

Characteristics of Foods for Dogs with Kidney Disease

best food for dog with kidney disease

There are a couple of key guidelines to keep in mind when finding food for a dog with kidney issues. Keep in mind that all foods designed to treat kidney disease that are currently on the market require veterinary authorization.

Here are a couple of characteristics of foods for dogs with kidney disease. 

  • They’re typically lower in protein. These foods are usually lower in protein content which reduces the strain on the kidneys, which must filter out protein waste products. This can help preserve kidney function and prevent further damage. The recommended protein range for dogs with kidney disease  is less than or equal to 14 to 20 percent on a dry-matter basis. 
  • Kidney-supporting foods feature reduced salt content. Sodium and salt levels are reduced in foods specialized for kidney issues as this reduces the workload on the kidneys. In addition, it can help affected doggos maintain a reasonable blood pressure level. 
  • Kidney-supporting foods feature reduced phosphorus. Though it’s reasoning is unclear, limiting the amount of phosphorus along with protein in a dog’s diet can help delay the progression of chronic kidney disease. The recommended phosphorus content for dogs suffering kidney disease is somewhere between 0.2 and 0.5 percent on a dry-matter basis.  
  • The best kidney-friendly foods contain plenty of omega-3s. Omega-3 fatty acids can help reduce inflammation which can ease the progression of chronic kidney disease. 

Note that it is often wise to consider wet or canned options for dogs with kidney disease.

Dogs suffering from kidney disease need more water than healthy doggos, so you’ll not only want to encourage your dog to drink lots of water (you can attempt this through the use of a dog water fountain), you may want to give your dog a food with much greater water content too, like a quality canned wet food.

Your Options Are Limited

It is important to understand that there simply aren’t that many kidney-friendly dog foods on the market.

Accordingly, we’ve had to recommend a few that don’t meet the criteria we typically impose on foods we recommend.

In some cases, this is the result of the foods’ specific goals. For example, several kidney-supporting dog foods feature very low protein levels or proteins that are situated farther down the ingredient list than we’d like. This is unavoidable to an extent, as kidney-friendly foods must have reduced protein content.

However, there are also foods listed below that feature incompletely labelled by-products and other animal-based foods.

We’d normally avoid recommending such foods, but because there are only a handful of foods available for dogs with kidney ailments, we have no choice but to include them here.

What Causes Kidney Disease in Dogs?

kidney function
Image from VCA Animal Hospitals.

As mentioned, acute kidney disease is usually caused by your dog ingesting something toxic. This could be antifreeze, ibuprofen, chemical cleaners, or anything around the house that is poisonous to dogs. One of the best ways to keep your pooch safe is to make sure that anything potentially dangerous is far from Fido’s reach. 

The cause of chronic kidney disease is a little more difficult to pin down, but it can generally be attributed to one of the following factors:

  • Aging process — As dogs become older, many body functions can naturally slow down. This includes activity in the kidneys, and chronic kidney disease is more likely to prevent itself later in your dog’s life. 
  • Underlying illness —  Many underlying illnesses can be the root cause of your dog’s kidney disease, as they can compromise the body’s ability to filter out toxins. 
  • Dental problems — Dental issues can open the door for harmful bacteria to enter the bloodstream which can cause irreversible damage to the kidneys and other organ systems.
old dogs can suffer kidney disease

Additionally, congenital and hereditary diseases can lead to kidney failure. Certain dog breeds like German shepherds and bull terriers may be more prone to developing kidney diseases based on their genetic background.

Your pooch may also be predisposed to kidney complications depending on his family health history. 

It’s important to see your veterinarian as soon as you notice any signs of kidney disease for a thorough diagnosis. 

What Happens When a Dog Suffers from Kidney Disease?

dog getting vet treatment

Remember that there are both chronic and acute forms of kidney disease.

We’re primarily focusing on the chronic form here, but if your dog is showing signs of kidney disease after ingesting something toxic, he likely has an acute case that needs to be treated immediately.

In such cases, you’ll simply need to make your way to the nearest pet hospital or care facility pronto. However, chronic kidney disease is a long-term, rather than emergent problem.

As your dog ages or his chronic kidney disease progresses, he will become less capable of efficiently filtering his blood. Subsequently, his body must increase the amount of blood flowing through the kidneys to lower the concentration of toxins. 

This can lead to increased water intake and a higher production of urine than normal. Your dog’s blood pressure will likely change too, though you obviously won’t notice this (there are no outward signs of high blood pressure).

Unfortunately, chronic kidney disease is typically a lifelong condition that requires permanent management under the direction of your veterinarian. 

Symptoms of Kidney Disease In Dogs

It’s critical to know what to look out for when it comes to kidney disease as the acute form of the disease can be life-threatening. Even if your dog is “only” suffering from the chronic form, you’ll need veterinary guidance to ensure he stays as healthy and happy as possible.  

Here are a few key signs your pooch may be suffering from kidney issues:

  • Increased thirst
  • Increased urination
  • Depression
  • Weight loss
  • Decreased appetite
  • Vomiting
  • Bad breath
  • Weight loss
  • Blood in urine
  • Pale gums
  • Mouth sores

How Is Kidney Disease Treated in Dogs?


When you go in for an office visit, your vet will likely run a variety of tests to diagnose the problem. This may include a urinalysis to evaluate kidney function and a blood chemistry analysis to assess the function of your dog’s internal organs. 

Depending on your dog’s test results, your veterinarian will recommend a variety of treatment strategies to help Fido manage his condition.

Some of the most common treatments for chronic kidney disease in dogs include: 

  • Switching to a Kidney-Supporting Food — As discussed earlier, most dogs with chronic kidney disease will require a specialized food that won’t cause the kidneys to work harder than they have to. These foods still offer a balanced diet while being gentler on your dog’s system.
  • Medications — Your veterinarian may prescribe various medications to manage the symptoms associated with the kidney issues at hand. This may include medications to help the body eliminate phosphorus, reduce stomach acid, control blood pressure, prevent vomiting, stimulate red blood cell production, or regulate the parathyroid gland which controls calcium levels in the bloodstream. 
  • Supplements — Your vet may also recommend adding some supplements to Fido’s daily diet. This may include potassium supplements which can help regulate blood pressure. 
  • IV Fluids — Your pooch might be given intravenous fluids to help flush out the kidneys and bloodstream. This process helps remove toxic metabolites from his blood stream. The procedure can also replenish vital electrolytes like potassium. 
  • Treating the Underlying Issue — Since kidney issues are often a result of another underlying problem, your veterinarian will work to root out any associated ailments that may be overwhelming your dog’s kidneys. For instance, some canine companions with kidney disease have diabetes. 

Dog Kidney Disease FAQs

chihuahua at the vet

Supporting Spot following a kidney disease diagnosis can be challenging. Here are a couple of the most common kidney disease questions owners often have, with answers to help you maintain your mutt’s health. 

What is the best food for dogs with kidney disease?

Ultimately, the right renal diet depends on the individual needs of your dog. Since every pooch is different, it’s best to take this up with your veterinarian to find the best renal diet food for Fido.

That said, you’ll likely find that your vet recommends one of the therapeutic diets discussed above, as they’re some of the most common and trusted on the market today.

Is kidney disease painful for dogs?

Kidney disease and its associated symptoms can be extremely painful for your pooch, especially the formation of kidney stones (and passing) or any buildup of waste products in your pup’s system. As soon as you suspect an issue, it’s vital to see your veterinarian. Your pet care professional can help you come up with a treatment plan to keep your four-footer as comfortable as possible. 

As with any health condition, follow your vet’s orders closely, whether it’s sticking to a special renal diet, offering ample clean water, or giving medications.

How long can a dog live with kidney disease?

This answer largely depends on the stage of your dog’s kidney disease. Generally speaking, the earlier you catch the condition, the better chance you have of prolonging your pup’s life. Unfortunately, without treatment, the progression of kidney disease can be rapid, leading to renal failure.

Your vet will develop a treatment plan based around the stage of kidney disease your dog is in and what’s causing the kidney damage.

What are the signs of kidney disease in dogs?

Some common signs of kidney disease in dogs include lethargy, weight loss, pale gums, bad breath, and increased or decreased water intake.

You might also notice a change in your dog’s urine volume or infrequent or frequent urination. Be sure to give your vet a call whenever your pooch is exhibiting any of these symptoms. 

What human food can I feed my dog with kidney disease?

While there are dog-safe human foods you can share with most pups, you’ll need to run any treat by your veterinarian to make sure it fits within your dog’s kidney disease treatment plan. Don’t forget that dogs with kidney disease should have limited sodium, protein, and phosphorus intake — nutrient concerns often met with prescription kidney diets. 

What foods help repair a dog’s kidneys?

Unfortunately, you can’t fully repair kidneys, only support their future health. That being said, foods rich in omega-3 fatty acids can reduce inflammation and slow the progression of canine kidney disease. 

Your best bet is sticking with the therapeutic kidney diet prescribed by your doctor, with the nutrient profiles designed with a sodium, phosphorus, and protein restriction that’s more gentle for dogs with renal disease. These therapeutic diets are the best choice for dogs with renal disease but shouldn’t be fed to dogs without kidney disease.

What foods should dogs with kidney disease avoid?

Any dog with kidney disease should avoid foods high in sodium, protein, or phosphorus. More importantly, anything your dog consumes should be vetted by your vet to make sure it’s a good fit for his needs. 

Prescription kidney diets are typically recommended, as these have carefully measured amounts of protein, sodium levels, and more. The delicate balance of nutrients in such a specialized diet for dogs with kidney disease ensures your dog is getting what he needs for day-to-day life without stressing his system.

Why do dogs get kidney disease?

Dogs can get acute kidney disease from consuming something toxic like medication or antifreeze. Chronic kidney disease can be caused by a variety of genetic and environmental factors. Regular check-ups can help catch common signs of this disease and other chronic conditions early.

Keep your canine running at his best and support healthy kidney function by always offering him fresh water and serving proper nutrition. If you unsure what optimal nutrition looks like for your doggo, ask your vet.

Is kidney disease fatal in dogs?

Kidney disease that’s managed under the care of a veterinarian with regular check-ups and proper nutrition isn’t necessarily fatal for dogs though it can, unfortunately, shorten your dog’s lifespan. If left unaddressed, acute and chronic kidney disease can be fatal. 

Can dogs get a kidney transplant?

While pooch kidney transplants are possible, they are difficult to come by and extremely costly. Testing is somewhat limited and a kidney transplant study out of the University of California reported a risky 36% success rate. Unfortunately, even if your dog undergoes a successful transplant, he’ll likely have to take medications for the rest of his life. 


Under the direction of a pet care professional, pups with kidney disease can still maintain an enriching, fulfilling lifestyle. Make sure you speak to your veterinarian about the best way to transition your furry best friend to a kidney-friendly kibble or wet food before making the switch.

Hi Kate. I appreciate this list. I’m with another dog owner here that my dog will try the food one day and the next day he tries to bury it into the floor. I’ve spent so much money on good dog food for renal support that just goes into the trash. I’ve tried making it more enticing with acorn squash, non-fat cottage cheese, and other of his favorites, but Murphy-dawg just turns it away. I’m thinking of trying out the Renal Support Low Protein from Just Food for Dogs. Do you happen to have a review of that? Thanks a bunch.

Hey there, Angela. We haven’t looked at that specific recipe, but we have written about other JustFoodforDogs recipes, such as their customized meals.
Let us know how it works for your pup!


This kidney advice is about as bad as it gets. The carb filled, moisture deprived, nutrient lacking junk food equivalent food recommended here are terrible. With so much info out there about the benefits of real food and the detriment of this processed foods I am not sure how you can feel good about promoting these foods. Dogs don’t thrive like they can with real food which is also in part why there is more and more of a push for real food for our pets. If you are truly trying to help pets live a better, longer life, you should research for yourself and do so with unbiased paid for play research used by these food industry goliaths that aren’t out to help pets be healthier but instead line their pockets at the demise of our pets. This is wrong and you are perpetually their wrong doings by promoting their products.

However, because of his medical issues, this is really a question for your vet.

If he was healthy and you were just trying to get him to eat something, we’d recommend all of the typical things (some cooked chicken or beef, bits of cheese, dog-safe peanut butter, cooked white rice, etc.).
But given his issues and nutritional needs, you’ll need to run these things by your vet first.

Best of luck! Sorry we couldn’t be of help.

Thank you for writing such a helpful article. I just found out that Maggie has CKD. She is 11yrs old. I am fortunate she is asymptomatic and pray that continues until I can get a handle on lowering her kidney values, by changing her food. I do not want to place her on meds, she is already on seizure meds. Seizures came out of no where and started winter 2020. Thank you again for helping our fury loved ones. Annemarie

Looking for a tiny kibble for my Chihuahua-the Purina is too big. Any of these other brands come in a smaller size?

Hey there, Tonisa. Not sure if this helps, but the Blue Buffalo kibble was described by one owner as “Cheerio-sized.”
Best of luck!
