Chronic kidney disease in dogs is typically managed with a combination of dietary strategies and veterinarian-directed medications that support appetite, blood pressure control and mineral balance.
While the condition cannot be cured, veterinarians often begin with commercially available medications and dietary strategies that are well studied and widely used in dogs with chronic kidney disease. These treatments aim to stabilize clinical signs and support quality of life over time, with adjustments made as a dog’s needs evolve.
This article explains how kidney disease is approached in dogs, which treatments are most commonly prescribed and how compounded formulations may support consistent long-term care under veterinary guidance.
What Is Kidney Disease in Dogs?
Kidney disease in dogs refers to a progressive loss of kidney function that affects the body’s ability to filter waste products, regulate hydration and maintain electrolyte balance.
Which Dogs Are at Higher Risk of Kidney Disease?
Middle-aged to older dogs are most commonly diagnosed with kidney disease, although it can occur at any age depending on underlying causes.
How Do Veterinarians Diagnose Kidney Disease?
A combination of bloodwork, urine testing and clinical assessment are used by veterinarians to diagnose and stage kidney disease.
International Renal Interest Society (IRIS) staging is widely used to help guide monitoring and management decisions in dogs with chronic kidney disease.
Why Are Medications Used as a Treatment for Kidney Disease in Dogs?
Dietary management is foundational in canine kidney disease, but medications are often added to address specific complications that develop as kidney function declines.
In many cases, these medications are prescribed in standard, commercially manufactured forms. When dogs have difficulty tolerating or taking these products, veterinarians may consider formulation alternatives to support consistency and comfort.
These may include:
- Reduced appetite
- Elevated blood pressure
- Disturbances in phosphorus balance
Rather than following a single protocol, veterinarians tailor medication choices to each dog’s clinical picture, adjusting recommendations over time as disease progression and response to therapy change.
How Do You Treat Kidney Disease in Dogs Effectively?
Treatment for kidney disease in dogs focuses on managing the complications that arise as kidney function declines, rather than curing the disease itself. Veterinarians typically take a multi-pronged approach.
The most common medication categories in dogs with chronic kidney disease include:
- Appetite stimulants, which may be used to support consistent food intake and help prevent weight loss or muscle wasting.
- Blood pressure medications, which help manage systemic hypertension that can worsen kidney damage and affect other organs.
- Phosphorus binders, which reduce phosphorus absorption from food when blood phosphorus levels become elevated despite dietary management.
These medication categories include several commercially available options that veterinarians commonly prescribe, selected based on laboratory findings, blood pressure measurements and clinical signs.
Commonly prescribed examples across these categories may include appetite stimulants such as mirtazapine, blood pressure medications such as amlodipine or telmisartan, and phosphorus binders such as aluminum hydroxide or calcium carbonate, depending on the individual dog’s needs.
The sections below explore each of these medication types in more detail, including why they’re used, what role they play in kidney disease management and how formulation options—such as compounding—may help support long-term care.
What Are Appetite Stimulants for Dogs With Kidney Disease?
Appetite stimulants for dogs are prescribed to help encourage food intake, not to treat kidney disease itself. These medications are available in commercially manufactured forms, and the goal is to support nutritional status and overall comfort while other aspects of kidney care are addressed.
Appetite stimulants commonly discussed in dogs with kidney disease include mirtazapine, which is available in FDA-approved oral formulations, and capromorelin (Entyce®), an FDA-approved appetite stimulant labeled for use in dogs. In some cases, veterinarians may also prescribe compounded formulations of appetite-supporting medications to better match a dog’s size, tolerance or administration preferences. Appetite stimulants are used to support caloric intake and body condition rather than directly affecting kidney function.
Decreased appetite is a common concern in dogs with kidney disease and may contribute to:
- Weight loss
- Muscle wasting
- Reduced energy
Veterinarians may discuss appetite stimulants when a dog shows persistent reluctance to eat despite dietary adjustments.
Compounded formulations may be considered when a dog requires a customized strength, an alternative dosage form or improved palatability to support consistent administration.
Why Are Blood Pressure Medications Used for Kidney Disease in Dogs?
Systemic hypertension is commonly identified in dogs with chronic kidney disease and may contribute to further kidney injury if left unmanaged. For this reason, veterinarians often monitor blood pressure as part of routine kidney disease evaluation.
When elevated blood pressure is identified, antihypertensive medications may be prescribed to help reduce strain on the kidneys and other organs, such as the eyes and heart.
Antihypertensive medications prescribed for dogs with kidney disease may include calcium channel blockers such as amlodipine, angiotensin-converting enzyme inhibitors such as enalapril or benazepril, or angiotensin receptor blockers such as telmisartan, depending on blood pressure measurements and concurrent clinical findings.
Blood pressure management is individualized and requires ongoing reassessment by a veterinarian.
What Are Phosphorus Binders for Dogs With Kidney Disease?
Phosphorus binders for dogs work within the gastrointestinal tract to reduce phosphorus absorption from food. They are prescribed only under veterinary supervision and selected based on a dog’s laboratory values, diet and tolerance. Consistency in administration is important, particularly in dogs requiring long-term use.
Common phosphorus binders prescribed in dogs include aluminum hydroxide and calcium carbonate. These products may be available as commercial supplements or prepared as compounded formulations to support accurate dosing and palatability under veterinary guidance. Phosphorus binders act locally within the gastrointestinal tract rather than systemically.
As kidney function declines, phosphorus regulation may become impaired, leading to elevated blood phosphorus levels. Veterinarians often address phosphorus balance through diet first, but phosphorus binders may be discussed when dietary measures alone are insufficient.
Veterinary nutrition and internal medicine specialists frequently reference phosphorus control as part of comprehensive kidney disease management.

Can Kidney Disease Medications for Dogs Be Compounded?
While many dogs with kidney disease do well on commercially available medications, compounding may be discussed in certain situations to support individualized care. In many cases, you can request a compounded treatment for kidney disease in dogs. Compounding pharmacies, including Mixlab, allow medications to be prepared in strengths and dosage forms tailored to an individual dog’s prescription.
Common medications to treat hypertension related to kidney dysfunction are benazepril and enalapril. Mixlab can compound these as flavored suspension, capsule, tablet and even transdermal gel. Supplementing with Calcitriol can also add renal protection.
This is especially helpful for dogs with kidney disease, who often require multiple medications given daily over extended periods.
Veterinarians may discuss compounded formulations when a dog needs:
- A dose not commercially available
- A formulation that is easier to administer, such as a flavored liquid
- Improved palatability to support adherence
Compounding does not replace veterinary oversight or monitoring. It is one tool veterinarians may use to help support consistency and practicality in long-term kidney disease care.
The Importance of Monitoring and Long-Term Management
Kidney disease management is an ongoing process. Veterinarians typically monitor dogs with chronic kidney disease through periodic:
- Laboratory testing
- Blood pressure assessment
- Evaluation of appetite, hydration and body condition
Medication needs may change over time as disease progresses or stabilizes. Regular communication between dog owners and veterinarians helps ensure that therapy remains appropriate and aligned with the dog’s current needs.
Frequently Asked Questions: Treatment for Kidney Disease in Dogs
What Is the Most Common Treatment for Kidney Disease in Dogs?
There is not one answer—the specific medications chosen depend on a dog’s laboratory values, clinical signs and disease stage.
Veterinarians may prescribe medications that support appetite, help manage blood pressure or assist with phosphorus balance. These medications support management rather than curing kidney disease.
Do All Dogs With Kidney Disease Need Appetite Stimulants?
No. Some dogs maintain a good appetite with dietary changes alone. Appetite stimulants may be discussed when decreased food intake becomes a concern and nutritional status is at risk.
Why Is Blood Pressure Monitored in Dogs with Kidney Disease?
High blood pressure is commonly associated with chronic kidney disease and may contribute to further organ damage. Monitoring allows veterinarians to identify hypertension early and determine whether medication is appropriate.
Are Phosphorus Binders for Dogs Safe for Long-term Use?
Phosphorus binders may be prescribed for long-term use when clinically indicated.
Safety depends on:
- Appropriate product selection
- Consistent administration
- Ongoing veterinary monitoring
Can a Treatment for Kidney Disease in Dogs Be Compounded?
Yes. When prescribed by a veterinarian, a treatment for kidney disease in dogs can often be compounded to provide customized strengths or alternative dosage forms that support consistent administration.
Which medications are commonly used to manage kidney disease in dogs?
Veterinarians may prescribe medications such as mirtazapine or capromorelin to support appetite, amlodipine or telmisartan to manage blood pressure, and aluminum hydroxide or calcium-based binders to help control phosphorus levels. The specific combination depends on laboratory findings, disease stage, and how the dog is responding to treatment.
