Chronic Kidney Disease in Dogs

Chronic kidney disease (CKD) is a common condition in older dogs. Unlike cats, dogs may not show obvious signs of kidney disease until significant damage has already occurred. In many cases, symptoms don’t become noticeable until approximately 60–70% of kidney function has been affected.

The good news is that when kidney disease is detected early, we can often slow its progression and help your dog maintain a good quality of life. While there is no cure for chronic kidney disease, there are many ways we can manage the condition, control symptoms, and keep your dog comfortable.

What Do the Kidneys Do?

The kidneys play several important roles in your dog’s body. They help:

• Remove waste products from the bloodstream

• Maintain proper fluid and electrolyte balance

• Regulate blood pressure

• Support red blood cell production

• Help maintain overall body balance and health

When kidney function declines, these important processes can be affected.

What Are the Signs of Kidney Disease?

The early signs of chronic kidney disease can be subtle and may look like other health problems. Common symptoms include:

• Increased thirst and drinking

• Increased urination or larger amounts of urine

• Decreased appetite

• Weight loss

• Muscle loss, particularly in older dogs

• Changes in energy levels

Because these symptoms can occur with many different conditions, diagnostic testing is important to determine what is actually affecting your dog.

How Is Kidney Disease Diagnosed?

The first step in diagnosing chronic kidney disease is bloodwork and urine testing.

Blood and urine samples allow us to evaluate kidney function and look for other changes that may be occurring throughout the body. Bloodwork can also provide information about the liver, pancreas, red and white blood cells, and other important areas of your dog’s health.

Once we have the results, we can determine the severity of the kidney disease and develop a treatment plan specifically suited to your dog.

The Four Stages of Kidney Disease

Chronic kidney disease is generally divided into four stages:

Stage 1: Mild or early kidney changes

Stage 2: Mild to moderate kidney disease

Stage 3: Moderate to severe kidney disease

Stage 4: Severe or end-stage kidney disease

Staging helps us understand how advanced the disease is and guides decisions about diet, medications, supplements, and monitoring.

How Is Kidney Disease Managed?

Once your dog has been diagnosed with chronic kidney disease, treatment focuses on supporting kidney function and managing the effects of the disease.

Depending on your dog’s individual needs, treatment may include:

Kidney-Specific Diet

A prescription kidney diet can help reduce the workload on the kidneys and provide appropriate levels of nutrients to support your dog’s health.

Medications

Some dogs benefit from medications to help manage complications associated with kidney disease, such as blood pressure changes, nausea, or other symptoms.

Nutritional Supplements

Certain supplements may be recommended to provide additional support and help manage specific changes associated with kidney disease.

Regular Monitoring

Regular bloodwork and urine testing are important for tracking kidney function and identifying subtle changes before they become more serious. For many dogs with CKD, checking kidney values approximately every six months is a good way to monitor progression, although your veterinarian may recommend more frequent testing depending on your dog’s stage and overall health.

Can Dogs Live a Good Life With Kidney Disease?

Absolutely! Chronic kidney disease cannot be cured, but it can often be managed. With early detection, appropriate nutrition, medications when needed, and regular monitoring, many dogs with kidney disease can continue to enjoy a good quality of life.

If you have an older dog, routine wellness exams and bloodwork can help detect changes before your dog begins showing obvious symptoms. The earlier we identify kidney disease,

the sooner we can begin supporting your dog’s kidneys and slowing the progression of the disease.
