Understanding Kidney Stones in Dogs
Kidney stones can affect our beloved canine companions, causing discomfort and potentially leading to more serious health issues. Understanding the basics of kidney stones in dogs is essential for early detection and proper management.
Common Breeds at Risk
While kidney stones can occur in dogs of any breed, certain breeds are more susceptible to developing them. Toy breeds such as Miniature Schnauzers and Shih Tzus have a higher risk of kidney stones compared to larger breeds. It is important for owners of these breeds to be aware of the potential risk and take necessary precautions.
Formation of Kidney Stones
The formation of kidney stones in dogs is typically the result of imbalances in their urine or blood composition. The normal urine of a dog is slightly acidic and contains dissolved mineral products. However, when there are imbalances, such as an increase in certain minerals or a decrease in others, crystalline structures can form and eventually become kidney stones.
The exact causes of these imbalances can vary and may include factors such as genetics, diet, and underlying medical conditions. It is important to work closely with a veterinarian to determine the underlying cause and develop an appropriate treatment plan.
To diagnose kidney stones in dogs, veterinarians may perform diagnostic procedures such as abdominal X-rays or ultrasound. These imaging techniques can help visualize the presence and location of stones in the kidneys or urinary tract. Urinalysis is another important tool for diagnosis, as it can detect the presence of blood in the urine, abnormal pH levels, and the presence of crystals.

Symptoms and Diagnosis
When it comes to kidney stones in dogs, recognizing the signs and obtaining a proper diagnosis are crucial steps in ensuring the well-being of your furry friend.
Recognizing Signs
The presence of kidney stones in dogs can lead to various symptoms, although the most common characteristics are blood in the urine and pain during urination. However, it’s important to note that other symptoms may also indicate the presence of kidney stones. Some additional signs to watch out for include:
- Abdominal pain or discomfort
- Vomiting
- Swelling of the kidney
- Changes in urination patterns
In severe cases, a urinary obstruction may occur, which is a life-threatening emergency that requires immediate medical attention.
Diagnostic Procedures
To confirm the presence of kidney stones and determine the appropriate treatment approach, a veterinarian will perform diagnostic procedures. These procedures typically include a combination of the following:
-
Physical Examination: A complete physical examination allows the veterinarian to assess your dog’s overall health and identify any specific signs that may indicate kidney stones.
-
Urinalysis: A urinalysis is a crucial diagnostic tool that can detect the presence of blood in the urine, abnormal pH levels, and the presence of crystals. It helps in evaluating the overall health of the urinary system and provides important clues about the presence of kidney stones.
-
Imaging Tests: Abdominal X-rays or ultrasound are commonly used to visualize the kidneys and detect the presence of stones. These imaging tests provide detailed information about the size, location, and number of kidney stones present (Wag Walking).
Once the diagnosis of kidney stones is confirmed, the veterinarian can proceed with developing an appropriate treatment plan. Treatment options may include medical interventions or surgical procedures, depending on the severity and specific needs of your dog. To learn more about treatment options for kidney stones in dogs, refer to the section on Treatment Options.
By recognizing the signs and seeking timely veterinary care, you can ensure that your dog receives the necessary diagnosis and treatment for kidney stones. Remember, early detection and intervention can help prevent complications and promote the overall well-being of your canine companion.
Treatment Options
When it comes to treating kidney stones in dogs, there are various options available depending on the severity and type of stones. Treatment options for kidney stones in dogs include medical interventions and surgical procedures.
Medical Interventions
Medical interventions aim to manage and dissolve kidney stones in dogs through non-invasive methods. These interventions may include:
- Dietary Changes: Modifying the dog’s diet to promote stone dissolution and prevent further stone formation. A veterinarian may recommend a specific dog kidney stones diet that is tailored to the type of stones present.
- Medications: Prescription medications can be used to assist in the dissolution or prevention of certain types of kidney stones. However, the effectiveness of medication may vary depending on the size, composition, and location of the stones.
- Urohydropulsion: This procedure involves flushing out small stones from the urinary tract using a special technique with a urinary catheter. Urohydropulsion is typically used for smaller stones that can be safely expelled without the need for surgery.
It’s important to note that medical interventions may not be suitable for all cases of kidney stones, particularly if the stones are too large or causing severe obstruction. In such instances, surgical procedures may be necessary.
Surgical Procedures
Surgical procedures are often considered when kidney stones in dogs are causing significant obstruction, pain, or other complications. The specific surgical approach will depend on the size, location, and composition of the stones. Surgical procedures for kidney stones in dogs may include:
- Laser Lithotripsy: This procedure utilizes a laser to break down the stones into smaller fragments that can be flushed out of the urinary tract or retrieved with a small basket. Laser lithotripsy is a non-invasive alternative to traditional surgery and may be an option for certain cases.
- Surgical Removal: In more severe cases, surgical removal of the kidney stones may be necessary. Surgical removal is typically performed when stones are large, numerous, or causing significant obstruction. The veterinarian will determine the most appropriate surgical technique based on the individual dog’s condition.
It’s important to consult with a veterinarian to determine the best treatment approach for your dog’s specific case. They will consider factors such as the size and composition of the stones, the dog’s overall health, and the potential risks and benefits of each treatment option. Keep in mind that the cost of treating kidney stones in dogs can vary, with an average cost ranging from $800 to $7,500.

While bladder stones in dogs share some similarities with kidney stones, the treatment approaches can differ. To understand the differences, refer to our section on Comparing Bladder and Kidney Stones.
Types of Kidney Stones
Kidney stones in dogs can vary in composition, and understanding the different types is essential for proper diagnosis and treatment. The three most common types of kidney stones in dogs are calcium oxalate stones, struvite stones, and urate stones.
Calcium Oxalate Stones
Calcium oxalate stones are the most prevalent type of kidney stones in dogs, accounting for approximately 41.3% of all stone formations, as shown in one past study. These stones form due to an accumulation of calcium and oxalate crystals in the kidneys. While the exact cause of calcium oxalate stone formation is not fully understood, factors such as breed predisposition and dietary influences may play a role.
Diagnosing calcium oxalate stones in dogs often involves blood tests to check for high blood calcium levels and urinalysis to detect the presence of acidic urine and numerous calcium oxalate crystals. Imaging procedures like X-rays, ultrasounds, or contrast studies can help identify the stones in the kidneys, but the definitive composition of the stones can only be determined through analysis at a veterinary laboratory.
Treatment options for calcium oxalate stones depend on the size of the stones and the risk of urinary tract obstruction. Non-surgical removal, known as urohydropropulsion, involves flushing out small stones using a special urinary catheter technique. Surgical removal is recommended for larger stones, multiple stones, increased risk of urinary tract obstruction, or in male dogs due to their higher risk of obstruction. In some cases, ultrasonic dissolution may be available to break down the stones using high-frequency ultrasound waves. To prevent recurrence, dogs with calcium oxalate stones often require a therapeutic diet that promotes less acidic, more dilute urine. This diet typically involves avoiding high oxalate foods, calcium supplements, and vitamin C supplements.
Struvite Stones
Struvite stones, also known as magnesium ammonium phosphate stones, are more commonly found in female dogs. They often develop as a result of urinary tract infections (WebMD). The formation of struvite stones is associated with the presence of certain bacteria that produce urease, an enzyme that increases urinary pH and promotes stone formation.
Diagnosing struvite stones typically involves urinalysis to detect alkaline urine and the presence of struvite crystals. Imaging procedures like X-rays or ultrasounds can help confirm the presence of stones in the kidneys.
Treatment for struvite stones involves addressing the underlying urinary tract infection and dissolving the stones. This is typically achieved through antibiotic therapy to eliminate the infection and a specific diet that promotes the dissolution of struvite stones. Regular monitoring of urine pH and urinalysis is essential to ensure the effectiveness of the treatment and prevent recurrence. In some cases, surgical removal of large or obstructive stones may be necessary.
Urate Stones
Urate stones are commonly found in certain dog breeds, particularly Dalmatians. These stones form due to the accumulation of uric acid crystals in the kidneys. Dalmatians have a genetic predisposition to inefficient uric acid metabolism, leading to higher uric acid levels in the urine and an increased risk of stone formation.
Diagnosing urate stones in dogs often involves urinalysis to detect the presence of uric acid crystals and imaging procedures like X-rays or ultrasounds to confirm the presence of stones in the kidneys.
Treatment for urate stones typically involves a combination of dietary changes, medication, and increased hydration. A low-purine diet is often recommended to reduce the production of uric acid. Medications may be prescribed to help dissolve the stones or manage underlying metabolic conditions. Adequate hydration is crucial to promote urine dilution and reduce the risk of stone formation.
Understanding the different types of kidney stones in dogs is essential for accurate diagnosis and appropriate treatment. If you suspect your dog may have kidney stones, it’s important to consult with a veterinarian for proper evaluation and guidance.
Prevention and Management
When it comes to preventing and managing kidney stones in dogs, proactive measures are essential. By taking steps to address diet and hydration, as well as implementing recurrence prevention strategies, dog owners can help minimize the risk and impact of kidney stones.
Diet and Hydration
Diet plays a crucial role in preventing kidney stones in dogs. Providing a well-balanced and appropriate diet can help maintain the optimal urinary environment and reduce the formation of stones. It is recommended to consult with a veterinarian to determine the most suitable diet for your dog based on their specific needs and any underlying health conditions.
For dogs prone to certain types of kidney stones, such as calcium oxalate stones or struvite stones, dietary modifications are often necessary. For instance, dogs with calcium oxalate bladder stones may benefit from a diet that promotes less acidic and more dilute urine, while avoiding high oxalate foods, calcium supplements, and vitamin C supplements. Regular monitoring through urinalysis, bladder X-rays, and urine tests can help detect any potential issues early on.
Hydration is also a vital aspect of preventing kidney stones in dogs. Adequate water intake promotes the dilution of urinary crystals, allowing them to dissolve or be flushed from the system before forming into stones. Encourage your dog to drink plenty of fresh, clean water throughout the day. If your dog is not drinking enough water, consult with your veterinarian for guidance on how to increase their water intake. Ensuring access to fresh water at all times is essential.
Recurrence Prevention
For dogs that have experienced kidney stones, recurrence prevention is crucial. Monitoring and managing kidney stones may involve regular lab tests to assess kidney function and urine quality, as well as imaging rechecks with radiographs or ultrasound to ensure stones are not growing or causing complications (Pet Health Network). It is essential to follow the recommended treatment plan and maintain regular communication with your veterinarian to ensure the best outcomes.
In some cases, veterinary urologists may employ special techniques to break stones into smaller pieces, facilitating their passage through the urine. Antibiotics, diet changes, increased water intake, and, in certain instances, surgery may be part of the treatment approach for managing kidney stones in dogs (Pet Health Network). The specific course of action will depend on the type, size, and location of the stones, as well as the overall health of the dog.
By remaining vigilant and staying proactive in the prevention and management of kidney stones in dogs, pet owners can help minimize the occurrence and impact of this condition. Remember to consult with a veterinarian for personalized advice and guidance tailored to your dog’s specific needs. Additionally, considering natural remedies in conjunction with veterinary recommendations may provide additional support.
Comparing Bladder and Kidney Stones
When it comes to urinary stones in dogs, it’s important to differentiate between bladder stones and kidney stones. While they share similarities, there are key differences in their location, symptoms, and treatment approaches.
Location and Symptoms
Most urinary stones in dogs are located in the urethra and the urinary bladder. Bladder stones, as the name suggests, develop within the bladder. On the other hand, kidney stones form in the kidneys themselves. The symptoms of these stones differ based on their location (WebMD).
Bladder Stones
The most common signs of bladder stones in dogs include:
- Blood in the urine
- Abdominal discomfort
- Urinary accidents
- Urination in small amounts
- Difficulty urinating
In some cases, bladder stones can cause urinary obstruction, which is a serious condition requiring immediate emergency treatment. Male dogs are more prone to urinary obstruction due to their longer and narrower urethra (VCA Hospitals).
Kidney Stones
Kidney stones, on the other hand, may not always present obvious symptoms. However, dogs with kidney stones may experience:
- Flank pain
- Blood in the urine
- Increased thirst
- Frequent urination
- Urinary accidents
In some cases, kidney stones may cause urinary obstruction, which requires prompt veterinary attention.
Treatment Approaches
When it comes to the treatment of bladder and kidney stones in dogs, there are various approaches depending on the specific circumstances and the type of stone involved.
Bladder Stone Treatment
Treatment options for bladder stones in dogs may include:
- Surgical removal: In many cases, bladder stones are surgically removed. This procedure is typically performed by a veterinarian.
- Non-surgical removal: Some bladder stones can be removed through a procedure called urohydropropulsion, which involves flushing the stones out of the bladder using a special catheter.
- Dietary dissolution: In certain cases, bladder stones can be dissolved through a specialized diet that helps break them down over time (VCA Hospitals).
Kidney Stone Treatment
Kidney stones in dogs often require medical intervention. Treatment options may include:
- Surgical removal: In some cases, surgical removal of kidney stones may be necessary. This procedure is typically performed by a veterinarian experienced in urologic surgery.
- Interventional radiology: Another treatment approach involves interventional radiology, where a laser fiber is directed onto the kidney stone through a cystoscopy to break the stone into small pieces.
- Management of underlying causes: In addition to specific stone treatments, addressing underlying factors such as diet and hydration may help prevent or manage the formation of kidney stones (WebMD).
By understanding the differences between bladder and kidney stones, dog owners can better recognize the signs and seek appropriate veterinary care. It’s important to consult with a veterinarian for an accurate diagnosis and tailored treatment plan for your dog’s specific condition.
