Polycystic Kidney Disease

Polycystic Kidney Disease

Polycystic Kidney Disease (PKD) is a genetic disorder that affects a dog’s kidneys, causing the gradual formation of multiple fluid-filled cysts within the kidney tissue. Over time, these cysts enlarge and replace normal kidney tissue, reducing the organ’s ability to filter waste and maintain fluid balance. PKD is a progressive and inherited condition, meaning it worsens with age and is often passed down from parent dogs.

Dogs suffering from Polycystic Kidney Disease may not show signs early on, as the cysts grow slowly. However, as the disease advances, common symptoms include increased thirst, frequent urination, loss of appetite, weight loss, vomiting, and lethargy. In more severe stages, affected dogs may also develop high blood pressure, kidney failure, and a dull coat condition. Because the symptoms can resemble other kidney issues, early veterinary screening is important, especially in predisposed breeds.

The primary cause of PKD is genetic mutation, most commonly inherited in an autosomal dominant pattern, meaning that even one affected parent can pass the condition to offspring. The cysts usually begin forming early in life but may not cause symptoms until the dog reaches middle or senior age. Although the condition cannot be cured, early detection and management can help slow its progression and improve the dog’s quality of life.

Dog Breeds Commonly Affected by Polycystic Kidney Disease

Polycystic Kidney Disease can occur in any breed, but it’s more frequently seen in certain purebred lines, including:

• Bull Terriers
• Cairn Terriers
• Beagles
• West Highland White Terriers
• Shih Tzus
• Soft-Coated Wheaten Terriers
• Samoyeds
• Staffordshire Bull Terriers
• Golden Retrievers
• Doberman Pinschers

Diagnosis is typically made using ultrasound imaging, which allows veterinarians to visualize the cysts in the kidneys. In some cases, genetic testing can confirm the presence of PKD genes, especially for breeding dogs. While there’s no specific cure, treatment focuses on managing symptoms and slowing kidney damage through dietary changes, fluid therapy, blood pressure management, and kidney-supportive medications.

Maintaining a low-protein, low-phosphorus diet, providing plenty of fresh water, and scheduling regular veterinary checkups are essential for managing PKD. Early diagnosis and careful monitoring can help affected dogs live longer and more comfortable lives despite the disease
