Kidney stones in dogs, while not exceedingly common, can cause significant discomfort and lead to severe complications if left untreated. Understanding the causes, recognizing the symptoms, and knowing the available treatments can help pet owners ensure the well-being of their furry friends. In this article, we’ll delve into everything you need to know about kidney stones in dogs, from causes to treatments.
What Are Kidney Stones?
Kidney stones, medically known as nephroliths, are hard mineral and crystalline deposits that form in the kidneys. They can vary in size and may cause blockages in the urinary tract, leading to severe pain and other health issues. These stones are often composed of minerals such as calcium, struvite, and uric acid.
Causes of Kidney Stones in Dogs
Understanding the causes of kidney stones in dogs can help in prevention and early detection. Here are some common causes:
Dietary Factors
Certain diets can contribute to the formation of kidney stones. High levels of calcium, protein, or magnesium in a dog’s diet can increase the risk. Additionally, inadequate water intake can lead to concentrated urine, promoting stone formation.
Genetic Predisposition
Some dog breeds are more prone to developing kidney stones due to genetic factors. Breeds like Dalmatians, Miniature Schnauzers, and Bulldogs have a higher risk. If you own one of these breeds, regular check-ups with your veterinarian are crucial.
Underlying Health Conditions
Certain health conditions, such as urinary tract infections, can increase the likelihood of kidney stone formation. Dogs with hyperparathyroidism or those taking certain medications may also be at risk.

Recognizing the symptoms of kidney stones in dogs is vital for early intervention. Here are some common symptoms:
Pain and Discomfort
Dogs with kidney stones may exhibit signs of pain, such as whining, restlessness, or avoiding physical activity. They may also show discomfort when urinating.
Changes in Urination
Frequent urination, difficulty urinating, or blood in the urine are common indicators of kidney stones. If you notice these symptoms, consult your veterinarian immediately.
Lethargy and Loss of Appetite
Kidney stones can cause your dog to feel unwell, leading to lethargy and a decrease in appetite. Weight loss may also occur over time.
Diagnosing Kidney Stones in Dogs
Diagnosing kidney stones in dogs typically involves a combination of physical examination, medical history, and diagnostic tests.
Physical Examination
Your veterinarian will perform a physical examination and discuss your dog’s medical history and symptoms. They may palpate the abdomen to check for signs of pain or discomfort.
Imaging Tests
Imaging tests such as X-rays or ultrasounds are commonly used to visualize kidney stones. These tests help determine the size, location, and number of stones present.
Urinalysis
A urinalysis can provide valuable information about your dog’s urinary health. It can detect the presence of blood, crystals, or infection, which may indicate kidney stones.
Treatment Options for Kidney Stones in Dogs

Treatment for kidney stones in dogs depends on the size, location, and number of stones, as well as the overall health of the dog.
Dietary Modifications
In some cases, dietary changes can help dissolve certain types of kidney stones. Your veterinarian may recommend a special diet low in calcium, protein, or magnesium to prevent further stone formation.
Medications
Medications may be prescribed to manage pain or treat any underlying infections. In some cases, medications can help dissolve stones or prevent new ones from forming.
Surgical Intervention
For larger stones or those causing a blockage, surgical intervention may be necessary. Procedures such as cystotomy or nephrotomy can be performed to remove the stones and alleviate symptoms.
Extracorporeal Shock Wave Lithotripsy (ESWL)
ESWL is a non-invasive procedure that uses sound waves to break kidney stones into smaller pieces, allowing them to pass more easily. This option may be suitable for certain cases, depending on the stone’s size and location.
Preventing Kidney Stones in Dogs
Preventing kidney stones in dogs involves maintaining a healthy lifestyle and regular veterinary check-ups. Here are some preventive measures:
Adequate Hydration
Ensure your dog has access to fresh, clean water at all times. Proper hydration helps dilute urine, reducing the risk of stone formation.
Balanced Diet
Feed your dog a balanced diet appropriate for their breed, age, and health status. Avoid over-supplementing with minerals like calcium and magnesium.
Regular Veterinary Check-Ups
Regular visits to the veterinarian can help detect early signs of kidney stones or other urinary issues. Your vet can provide tailored advice based on your dog’s specific needs.
Conclusion
Kidney stones in dogs can be a challenging condition, but with the right knowledge and care, pet owners can manage and prevent this issue effectively. Understanding the causes, recognizing the symptoms, and seeking timely veterinary care are crucial steps in ensuring your dog’s health and well-being. By taking preventive measures and working closely with your veterinarian, you can help your furry friend live a happy, healthy life free from the discomfort of kidney stones.
