Kidney Failure in Dogs: What Every Pet Owner Should Know


As a pet owner, it is important to understand the health risks that your furry friend may face. One of the most common health issues that dogs can experience is kidney failure. This condition can be life-threatening and requires immediate medical attention. In this article, we will discuss the causes, symptoms, and treatment options for kidney failure in dogs.

What is Kidney Failure?

Kidney failure, also known as renal failure, occurs when the kidneys are no longer able to function properly. The kidneys play a crucial role in the body by filtering waste products from the blood and maintaining the balance of fluids and electrolytes. When the kidneys fail, waste products and fluids can build up in the body, causing a range of symptoms and complications.

There are two types of kidney failure in dogs: acute and chronic. Acute kidney failure is a sudden and severe decline in kidney function, while chronic kidney failure is a gradual and progressive loss of kidney function over time.

Causes of Kidney Failure in Dogs

There are many potential causes of kidney failure in dogs, including:

  • Toxicity: Certain medications, chemicals, and plants can be toxic to the kidneys and cause damage over time.
  • Infection: Bacterial or viral infections can damage the kidneys and lead to kidney failure.
  • Dehydration: When a dog is dehydrated, the kidneys may not receive enough blood flow to function properly.
  • Genetics: Some breeds of dogs are more prone to kidney disease than others, such as the Bernese Mountain Dog and the Cocker Spaniel.
  • Aging: As dogs age, their kidneys may begin to decline in function.

Symptoms of Kidney Failure in Dogs

The symptoms of kidney failure in dogs can vary depending on the severity of the condition. Some common symptoms include:

  • Increased thirst: Dogs with kidney failure may drink more water than usual.
  • Decreased appetite: Dogs may lose their appetite and become lethargic.
  • Vomiting and diarrhea: Dogs may experience gastrointestinal symptoms as a result of kidney failure.
  • Weight loss: Dogs with kidney failure may experience significant weight loss.
  • Weakness and lethargy: Dogs may become weak and lethargic as the condition progresses.

Diagnosing Kidney Failure in Dogs

If you suspect that your dog is experiencing kidney failure, it is important to seek veterinary care immediately. Your veterinarian will perform a physical exam and may recommend bloodwork, urinalysis, and imaging tests to diagnose the condition.

Treatment Options for Kidney Failure in Dogs

There are several treatment options available for dogs with kidney failure, including:

  • Dietary changes: Your veterinarian may recommend a special diet that is low in protein and phosphorus to help support kidney function.
  • Fluid therapy: Dogs with kidney failure may require intravenous fluids to help flush toxins from the body and maintain hydration.
  • Medications: Your veterinarian may prescribe medications to help manage symptoms and support kidney function.
  • Dialysis: In severe cases of kidney failure, dialysis may be necessary to remove toxins from the blood.
  • Kidney transplant: In some cases, a kidney transplant may be an option for dogs with kidney failure.

Preventing Kidney Failure in Dogs

While not all cases of kidney failure can be prevented, there are steps that pet owners can take to help reduce the risk of this condition. These include:

  • Maintaining a healthy diet: Feeding your dog a balanced, high-quality diet can help support kidney function.
  • Providing plenty of water: Make sure your dog has access to clean, fresh water at all times.
  • Regular veterinary check-ups: Regular check-ups can help detect kidney disease early and prevent complications.
  • Monitoring medications: Some medications can be toxic to the kidneys, so it is important to follow your veterinarian’s instructions carefully.


Kidney failure is a serious health issue that can affect dogs of all ages and breeds. It is important to be aware of the causes, symptoms, and treatment options for this condition in order to provide the best possible care for your furry friend. By working closely with your veterinarian and taking steps to prevent kidney disease, you can help keep your dog healthy and happy for years to come.
