Understanding Kidney Failure in Dogs
When it comes to the health of our beloved canine companions, it’s essential to be aware of potential conditions that can arise, such as kidney failure. Understanding the basics of kidney failure in dogs can help pet owners recognize the symptoms and seek appropriate veterinary care. This section will cover the definition and causes of kidney failure, as well as the different types that can occur.
Definition and Causes
Kidney failure, also known as renal failure, occurs when the kidneys are unable to perform their essential functions effectively. The kidneys play a crucial role in filtering waste products, regulating fluid balance, and maintaining electrolyte levels in the body. When kidney function is compromised, toxins can build up in the bloodstream, leading to a range of health issues.
There are two primary types of kidney failure in dogs: acute kidney failure and chronic kidney failure.
Acute kidney failure typically occurs suddenly and is often caused by factors such as ingestion of toxins, severe dehydration, infections, or blockages in the urinary tract (causes of kidney failure in dogs). This type of kidney failure requires immediate veterinary attention, as it can be life-threatening if left untreated.
Chronic kidney failure, on the other hand, develops over time and is generally age-related and predetermined by genetics. Small dogs may show early signs of chronic kidney disease around ten to fourteen years of age, while large dogs may experience kidney failure as early as seven years of age due to their shorter lifespan (VCA Hospitals). Regular physical exams, annual wellness checkups, and twice-yearly wellness exams at the primary care veterinarian’s office can help detect any problems early, allowing for timely treatment planning (Rossmoyne Animal Emergency Trauma Center).

Types of Kidney Failure
In addition to acute and chronic kidney failure, there are further classifications based on the underlying causes. Some common types include:
-
Prerenal Kidney Failure: This type occurs when factors outside the kidneys, such as dehydration or decreased blood flow, impair their function.
-
Renal Kidney Failure: Renal kidney failure refers to damage directly affecting the kidneys themselves. This can be caused by various factors, including toxins, infections, immune system disorders, or certain medications.
-
Postrenal Kidney Failure: Postrenal kidney failure occurs when there is a blockage in the urinary tract, preventing the proper flow of urine from the kidneys. This can be caused by conditions such as bladder stones, tumors, or urinary tract obstructions.
Understanding the definition and types of kidney failure in dogs is crucial for recognizing the symptoms and seeking appropriate veterinary care. In the following sections, we will delve deeper into the symptoms, diagnosis, treatment options, and preventive measures for kidney failure in dogs.
Symptoms of Kidney Failure in Dogs
Recognizing the symptoms of kidney failure in dogs is crucial for early detection and intervention. The symptoms can vary depending on the stage and underlying causes of the condition. In this section, we will explore the early signs and advanced symptoms of kidney failure in dogs.
Early Signs
One of the earliest clinical signs of kidney failure in dogs is increased water consumption and urination, known as compensated renal failure. This is the body’s attempt to compensate for the impaired kidney function by flushing out toxins and maintaining hydration (VCA Hospitals). Other early signs may include:
- Increased thirst
- Increased urination
- Weight loss
- Decreased appetite
If you notice these early signs in your dog, it is important to consult with a veterinarian for further evaluation and diagnosis. Early detection can lead to more effective treatment and management of the condition.
Advanced Symptoms
As kidney failure progresses, more severe symptoms may manifest. These advanced symptoms indicate a significant decline in kidney function and may include:
- Lethargy and weakness
- Vomiting and diarrhea
- Bad breath
- Ulcers in the mouth
- Blood in the urine
- Seizures
- Depression
- Blindness
It is important to note that the symptoms of kidney failure can vary depending on factors such as the type of kidney failure, the extent of loss of function in the kidneys, the progression of the condition, and its underlying causes (Sharon Lakes Animal Hospital). If your dog exhibits any of these advanced symptoms, immediate veterinary attention is crucial to provide appropriate treatment and support.
It’s important to remember that the symptoms of kidney failure in dogs can be non-specific and may overlap with other health conditions. Therefore, it is essential to consult with a veterinarian for a proper diagnosis. Prompt identification and treatment can help manage the progression of kidney failure and improve the quality of life for your beloved pet.

Diagnosing Kidney Failure in Dogs
When it comes to diagnosing kidney failure in dogs, veterinarians rely on a combination of tests and indicators to determine the extent of the disease. Early detection is vital for effective treatment and management. In this section, we will explore the veterinary tests used and the indicators of kidney disease in dogs.
Veterinary Tests
To diagnose kidney disease in dogs, veterinarians utilize various tests that provide valuable insights into the overall kidney function and the extent of failure. These tests may include:
-
Complete Blood Profile: This test helps evaluate the overall health of the dog and provides information about kidney function. It measures parameters such as blood urea nitrogen (BUN) and blood creatinine (CREA) levels, which can indicate decreased kidney function (VCA Hospitals).
-
Chemical Blood Profile: A chemical blood profile provides a comprehensive analysis of various enzymes and chemicals in the blood. This helps evaluate kidney function and assess the levels of specific substances that may be indicative of kidney disease (Small Door Vet).
-
Complete Blood Count (CBC): A CBC measures the different types of blood cells. Abnormalities in the CBC may suggest an underlying condition, including kidney disease. It helps assess the overall health and well-being of the dog (Small Door Vet).
-
Urinalysis: A urinalysis involves examining the physical and chemical properties of the dog’s urine. This test is crucial in assessing kidney function. It can help identify abnormalities such as proteinuria (increased protein in the urine) and a low urine specific gravity (USpG), which are early indications of kidney failure (VCA Hospitals, Animal Hospital of Clemmons, Rossmoyne Animal Emergency Trauma Center).
Indicators of Kidney Disease
Certain indicators can help veterinarians identify the presence of kidney disease in dogs. These indicators include:
- Serum Dimethylarginine (SDMA): SDMA is a biological marker for kidney function. It can be used to detect early renal failure in dogs. SDMA concentrations increase before serum creatinine levels become elevated, allowing for earlier detection and treatment of kidney issues.
By performing a combination of these veterinary tests and assessing the indicators of kidney disease, veterinarians can diagnose kidney failure in dogs and determine the appropriate treatment plan. It’s important to consult a veterinarian if you suspect any symptoms of kidney failure in your dog. Early detection and intervention can significantly improve the prognosis and quality of life for dogs with kidney disease.
Treatment Options for Kidney Failure
When it comes to treating kidney failure in dogs, the approach varies depending on whether it is acute or chronic. Additionally, managing the symptoms associated with kidney failure plays a crucial role in providing comfort and improving the quality of life for affected dogs.
Acute vs. Chronic Treatment
Acute kidney failure in dogs can occur suddenly and is often caused by ingesting toxins, such as antifreeze, household cleaners, or bad food, as well as urinary obstructions that decrease blood flow to the kidneys (WebMD). Immediate veterinary attention is crucial in these cases to prevent further damage and maximize the chances of recovery.
The treatment for acute kidney failure typically focuses on addressing the underlying cause, providing supportive care, and managing symptoms. This may include intravenous fluids to maintain hydration, diuretics to promote urine production, medications to control blood pressure, and treatments to address any complications that may arise.
Chronic kidney failure, on the other hand, is a long-term condition commonly found in older dogs. It can be caused by various factors, such as dental disease, which can gradually affect kidney function over time. The treatment for chronic kidney failure aims to slow down the progression of the disease and improve the dog’s quality of life.
Managing Symptoms
Managing the symptoms associated with kidney failure is an essential aspect of treatment. This involves a multifaceted approach to address the specific needs of each dog. The following measures are commonly employed:
-
Fluid Therapy: Adequate hydration is crucial for dogs with kidney failure. Intravenous or subcutaneous fluids may be administered to maintain hydration and support kidney function.
-
Medications: Dogs with kidney failure may require medications to control blood pressure, manage electrolyte imbalances, and treat complications such as gastric ulcers that can arise as a result of kidney disease.
-
Kidney-Friendly Diet: A kidney-friendly diet plays a significant role in managing chronic kidney failure in dogs. These diets are designed to reduce the workload on the kidneys and promote overall well-being. Specific nutrients, nutritional supplements, or therapeutic diets may be recommended to slow the progression of the disease and enhance the dog’s quality of life.
-
Regular Monitoring: Dogs with kidney failure require regular veterinary check-ups and monitoring to assess kidney function, evaluate the effectiveness of treatment, and make any necessary adjustments.
The prognosis and course of treatment for kidney failure in dogs depend on the severity and stage of the disease. It’s important to work closely with a veterinarian to develop a tailored treatment plan that addresses the individual needs of your dog. With proper care and management, it is possible to improve the well-being and quality of life of dogs with kidney failure.
