Important Disclaimer: If your dog has been diagnosed with kidney disease (also called chronic kidney disease or CKD), always consult your veterinarian before introducing any new treats, foods, or supplements into their diet. Kidney disease requires careful dietary management, and what works for one dog may not be appropriate for another depending on the stage of disease, lab values, and overall health. This guide is intended to provide general information and should not replace professional veterinary advice.

Learning that your dog has kidney disease can be overwhelming. One of the first questions many owners ask is, “Can I still give my dog treats?” The answer is yes, but you need to be much more selective about what treats you offer. Dogs with kidney disease require a diet that is low in phosphorus, moderate in high-quality protein, and low in sodium. The wrong treats can accelerate kidney damage, while the right ones can maintain your dog’s quality of life and keep that tail wagging at treat time.

Kidney disease affects the kidneys’ ability to filter waste products from the blood. When the kidneys are compromised, substances like phosphorus, sodium, and certain protein byproducts can build up to dangerous levels. A kidney-friendly diet focuses on reducing the workload on the kidneys by limiting these substances while still providing adequate nutrition and hydration.

In this guide, we will cover what ingredients to avoid, what to look for in kidney-safe treats, review five of the best options available, and discuss how to keep treat time enjoyable for your dog without compromising their health. If your dog is also a senior, you may find additional helpful information in our guide on the best treats for senior dogs.

What Ingredients to Avoid with Kidney Disease  

Understanding what to keep away from your dog is just as important as knowing what to offer them. Here are the key ingredients and nutrients that dogs with kidney disease should avoid or consume in strictly limited quantities.

High-Phosphorus Ingredients  

Phosphorus is the number one nutrient to restrict in dogs with kidney disease. Healthy kidneys filter excess phosphorus out of the blood, but damaged kidneys cannot keep up. Elevated phosphorus levels accelerate kidney deterioration and can lead to serious complications including bone disease and mineralization of soft tissues. Avoid treats that contain or are high in:

• Bone meal or ground bone
• Organ meats like liver, kidney, and heart
• Dairy products (cheese, yogurt, milk-based treats)
• Fish with bones
• Egg yolks
• Legumes and lentils

High-Sodium Ingredients  

Excess sodium forces the kidneys to work harder and can contribute to high blood pressure, which is already a common complication of kidney disease. Steer clear of treats that list salt as an ingredient, as well as any jerky treats, processed meat treats, or commercial treats with added sodium. Even some dental chews contain more sodium than is appropriate for a kidney patient.

Excessive Protein  

This one is nuanced. Dogs with kidney disease do not need to eliminate protein entirely, but they need moderate amounts of high-quality protein. The issue is that protein metabolism produces waste products like blood urea nitrogen (BUN) that damaged kidneys struggle to clear. Treats that are extremely high in protein, such as jerky, bully sticks, and freeze-dried meat treats, should be given sparingly if at all. The protein your dog does eat should come from high-quality, highly digestible sources.

Artificial Additives  

Dogs with kidney disease are already dealing with compromised organ function. Adding artificial colors, flavors, preservatives, or chemical additives to their diet creates additional substances their body must process and eliminate. Stick to treats with clean, simple ingredient lists.

What to Look For in Kidney-Friendly Treats  

Now that you know what to avoid, here is what makes a treat safe and suitable for dogs with kidney disease.

Low Phosphorus Content  

The ideal kidney-friendly treat is naturally low in phosphorus. Fruits and vegetables are generally excellent low-phosphorus options. Sweet potatoes, carrots, green beans, watermelon, blueberries, and apples (without seeds) are all naturally low in phosphorus and safe for most dogs with kidney disease. When buying commercial treats, look for products that list their phosphorus content or are specifically formulated for renal diets.

Low Sodium  

Choose treats with no added salt. Single-ingredient vegetable and fruit treats are naturally low in sodium. For commercial treats, check the guaranteed analysis for sodium content and aim for products with less than 0.3% sodium on a dry matter basis.

Moderate Protein with High Digestibility  

If you do offer protein-based treats, choose those made from high-quality, easily digestible proteins in moderate amounts. Small, soft training treats with lower protein percentages are preferable to large, dense, protein-heavy chews.

High Moisture Content  

Hydration is critically important for dogs with kidney disease. Treats with higher moisture content, like fresh fruits and vegetables, help support hydration. Dehydrated or freeze-dried treats can be rehydrated before serving to add extra fluid intake.

Calorie Awareness  

Many dogs with kidney disease struggle to maintain a healthy weight, either losing weight due to decreased appetite or gaining weight due to reduced activity. Choose treats that fit within your dog’s caloric needs and adjust meal portions accordingly.

Best Dog Treats for Kidney Disease: Product Reviews  

We focused on treats that are low in phosphorus, low in sodium, and gentle on compromised kidneys. Here are five options that stand out for dogs with renal health challenges.

1. Wholesome Pride Sweet Potato Chews  

Wholesome Pride Sweet Potato Chews are one of the most widely recommended treats for dogs with kidney disease, and for good reason. These chews contain just one ingredient: dehydrated sweet potato. There are no additives, no preservatives, no added salt, and no fillers. Sweet potatoes are naturally low in phosphorus and sodium while being rich in dietary fiber, vitamins A and C, and beta-carotene.

The chewy texture provides some dental benefit and keeps dogs occupied longer than a quick bite-sized treat. They are also easily broken into smaller pieces for training or reward purposes.

2. Fruitables Skinny Minis  

Fruitables Skinny Minis are a brilliant option for dogs with kidney disease who still need regular treats for training or daily rewards. Each treat contains just 3 calories, making them one of the lowest-calorie options on the market. They are made primarily from fruits and vegetables, keeping the phosphorus and protein content naturally low. Available in flavors like pumpkin and mango, apple bacon, and watermelon, these treats offer variety without compromising kidney health.

The soft, chewy texture is easy for dogs of all ages and sizes to enjoy, including seniors with dental issues.

Hill’s Prescription Diet Kidney Care Treats are specifically formulated by veterinary nutritionists for dogs with kidney disease. These treats are designed to complement Hill’s Prescription Diet k/d food and feature controlled levels of phosphorus, reduced sodium, and therapeutic levels of nutrients that support kidney function. They are one of the few commercial treats that have been clinically studied and developed specifically for renal patients.

Because these are prescription treats, they typically require a veterinary authorization to purchase. While this adds a step to the buying process, it also provides an extra layer of assurance that the product is appropriate for dogs with kidney disease. The formulation is backed by Hill’s decades of clinical nutrition research.

Price range: $8-12

The simplified recipe reduces the number of potential irritants and makes it straightforward to assess the phosphorus and sodium content.

These treats are available in several protein options, including turkey and potato and salmon and potato. For dogs with kidney disease, the potato-based varieties tend to be the most kidney-friendly due to the lower phosphorus contribution from plant-based carbohydrates. The limited ingredient approach also benefits dogs with food sensitivities, which can sometimes accompany chronic kidney disease. If your dog also has diabetes, see our guide on the best treats for diabetic dogs for additional options.

Price range: $5-8

Pros:

• Limited ingredient list is easy to evaluate for kidney safety
• No corn, wheat, soy, dairy, or eggs

A Note on Heart Disease and Low-Sodium Treats  

Dogs with heart disease share a similar dietary need with kidney disease patients when it comes to sodium restriction. If your dog has been diagnosed with heart disease or is at risk, many of the treats recommended in this guide are also appropriate due to their low-sodium profiles. The Wholesome Pride Sweet Potato Chews and fresh vegetable options are particularly well-suited for dogs managing heart conditions. Always consult your veterinarian for specific dietary guidance related to your dog’s cardiac health.

Frequently Asked Questions  

Can dogs with kidney disease still have treats?  

Yes, dogs with kidney disease can absolutely still enjoy treats. The key is choosing treats that are low in phosphorus, low in sodium, and not excessively high in protein. Treats are an important part of the bond between you and your dog, and eliminating them entirely can reduce your dog’s quality of life unnecessarily. Work with your veterinarian to identify appropriate treat options based on your dog’s specific stage of kidney disease and lab values.

How much phosphorus is too much for a dog with kidney disease?  

The ideal phosphorus restriction depends on the stage of kidney disease. For dogs in early stages (IRIS Stage 1-2), moderate phosphorus restriction is typically sufficient. For dogs in later stages (IRIS Stage 3-4), more aggressive restriction is necessary. As a general guideline, veterinary nutritionists often recommend keeping phosphorus intake below 60 mg per kilogram of body weight per day for dogs with CKD. Your veterinarian can provide specific targets based on your dog’s blood work.

Are freeze-dried treats safe for dogs with kidney disease?  

Many freeze-dried treats are made from pure meat and are therefore high in both protein and phosphorus, which makes them less than ideal for dogs with kidney disease. However, freeze-dried fruit and vegetable treats can be excellent options. If your dog does well with limited amounts of protein, small quantities of freeze-dried treats used sparingly may be acceptable, but consult your veterinarian first. For a broader look at freeze-dried options, see our guide on best low-calorie dog treats.

Should I avoid all protein treats for my dog with kidney disease?  

No. Dogs with kidney disease still need protein; they just need it to be high-quality and in controlled amounts. The outdated recommendation to severely restrict protein has been replaced by a more nuanced approach that emphasizes moderate amounts of highly digestible, high-quality protein. The goal is to reduce the waste products of protein metabolism without creating protein malnutrition. Your veterinarian can advise on the appropriate protein level for your dog’s specific stage of CKD.

Can I give my dog with kidney disease dental chews?  

Some dental chews may be acceptable, but many contain higher levels of sodium and protein than is ideal for kidney patients. Check the ingredient list and nutritional analysis carefully. If dental health is a concern, discuss dental chew options directly with your veterinarian, who may recommend specific kidney-friendly alternatives. For general dental chew information, see our guide on the best dental chews for dogs.

What fruits and vegetables should I avoid giving a dog with kidney disease?  

While most fruits and vegetables are safe, there are some notable exceptions. Never give your dog grapes or raisins, as they can cause acute kidney failure even in healthy dogs. Avoid onions, garlic, and avocados, which are toxic to dogs regardless of kidney status. Bananas, while safe in small amounts, are relatively high in potassium and should be limited for dogs with advanced kidney disease where potassium regulation may be impaired.

How do I know if a treat is affecting my dog’s kidney disease?  

Regular veterinary check-ups with blood work and urinalysis are the most reliable way to monitor your dog’s kidney function. If you introduce new treats, pay attention to changes in water consumption, urination frequency, appetite, energy levels, and any signs of nausea or vomiting. Report any changes to your veterinarian. It is generally a good idea to introduce one new treat at a time and monitor for several days before adding another.

Conclusion  

A kidney disease diagnosis does not mean the end of treat time for your dog. By choosing treats that are low in phosphorus, low in sodium, and moderate in protein, you can continue to reward, train, and bond with your dog while supporting their kidney health. Whether you reach for the simplicity of Wholesome Pride Sweet Potato Chews, the clinical precision of Hill’s Prescription Diet Kidney Care Treats, or the zero-cost goodness of fresh carrots and green beans from your own kitchen, the right treats can make your dog’s life with kidney disease more enjoyable.

Always remember to consult your veterinarian before making any dietary changes for a dog with kidney disease.
