Understanding Kidney Stones in Dogs
When it comes to kidney stones in dogs, it is important to have a clear understanding of their formation, types, and the risk factors associated with them.
Formation and Types
Kidney stones, also known as renal calculi, are solid crystals that form in the kidneys. These stones can be made up of various substances, such as calcium, oxalate, struvite, or cystine. The most common types of kidney stones in dogs are calcium oxalate and struvite stones (Pet Health Network). Calcium oxalate stones are also commonly found in the bladder.
Calcium oxalate stones are formed due to an imbalance of calcium and oxalate in the urine. Struvite stones, on the other hand, are caused by chronic bacterial infection and consist of magnesium, ammonium, and phosphate. Other less common types of kidney stones include cystine stones, which are formed due to an inherited metabolic disorder.
Risk Factors and Predisposition
Several factors can increase a dog’s risk of developing kidney stones. Female dogs are more prone to kidney stones than males, and certain breeds have a higher predisposition to forming stones multiple times. Additionally, dogs with underlying medical conditions, such as urinary tract infections, obesity, or metabolic imbalances, are more susceptible to developing kidney stones (Pet Health Network).
It is important for dog owners to be aware of the signs and symptoms of kidney stones, which may include frequent urination, bloody urine, difficulty urinating, and discomfort in the abdominal area. If you notice any of these signs, it is advisable to consult a veterinarian for proper diagnosis and treatment options. Early detection and intervention can help prevent complications and provide the best possible outcome for your dog.

Prevention of Kidney Stones in Dogs
When it comes to preventing kidney stones in dogs, a proactive approach is essential. By implementing certain strategies, you can reduce the risk of kidney stone formation and promote your dog’s overall urinary health. Two key factors to consider are hydration and water intake, as well as dietary recommendations for prevention.
Hydration and Water Intake
Staying hydrated is crucial for preventing kidney stones in dogs, just as it is for humans. Ensuring that your dog has access to fresh, clean water at all times is essential. Adequate water intake helps dilute the chemicals that can contribute to the formation of kidney stones. It also promotes urine production, which aids in flushing out potential stone-forming substances from the urinary tract.
As a general rule, dogs should drink approximately one ounce of water per pound of body weight daily. However, this can vary depending on factors such as activity level, size, and overall health. It’s important to monitor your dog’s water intake and encourage them to drink more if necessary. If you notice any signs of decreased water consumption or increased thirst, consult your veterinarian to rule out any underlying health issues.
Dietary Recommendations for Prevention
Diet plays a crucial role in preventing kidney stones in dogs. Here are some dietary recommendations to consider:
-
Citrus Fruits: Citrus fruits like lemons, oranges, and grapefruits contain natural citrate, which can help reduce or block the formation of kidney stones (Healthline). Incorporating these fruits into your dog’s diet, in moderation and with guidance from your veterinarian, may help maintain proper urinary health.
-
Calcium-Rich Foods: Contrary to popular belief, consuming calcium-rich foods can actually help prevent kidney stones by keeping oxalate levels in check. Good sources of calcium for dogs include milk, yogurt, cheese, legumes, and dark green vegetables. It’s important to obtain calcium from natural food sources rather than relying solely on supplements (Healthline).
-
Limit Sodium Intake: High sodium levels in the body can promote calcium buildup in urine, potentially leading to kidney stone formation. Therefore, it is advisable to limit your dog’s salt intake and check labels on processed foods for sodium content. Opting for low-sodium or homemade meals can help reduce the risk of kidney stone formation.
-
Reduced Animal Protein: Animal proteins, such as red meat, pork, chicken, and eggs, can contribute to the production of uric acid and increase the risk of kidney stones. It is recommended to moderate the intake of animal proteins and focus on a balanced diet that includes appropriate amounts of high-quality protein from sources such as lean meats, fish, and plant-based proteins (Healthline).
It’s important to note that every dog is unique, and dietary recommendations may vary depending on factors such as breed, size, age, and any underlying health conditions. Consulting with your veterinarian is crucial to develop a tailored diet plan that suits your dog’s specific needs and helps prevent kidney stone formation.
By prioritizing hydration and implementing suitable dietary recommendations, you can significantly reduce the risk of kidney stone formation in your beloved canine companion. However, it’s always important to monitor your dog’s health and seek veterinary advice if you notice any signs of kidney stones or changes in their urinary habits.
Treatment Options for Kidney Stones in Dogs
When it comes to treating kidney stones in dogs, there are several options available, including medical interventions and surgical procedures.
Medical Interventions
Medical interventions are often the first line of treatment for kidney stones in dogs. These interventions may include:
-
Urohydropulsion: This technique involves flushing out smaller stones from the urinary tract using a catheter and a sterile saline solution. It can be an effective method for dogs with smaller stones that are causing discomfort or obstruction (Wag Walking).
-
Extracorporeal Shock Wave Lithotripsy (ESWL): ESWL uses shock waves to break down larger stones into smaller fragments, making them easier to pass through urine. This non-invasive procedure is often performed under anesthesia and may require multiple sessions (Wag Walking).
-
Medications: Depending on the type of kidney stones present, medications may be prescribed to acidify urine, increase water intake, and treat urinary tract infections. These medications aim to prevent stone growth and facilitate their dissolution (Pet Health Network).
-
Pain Management: Dogs with kidney stones may experience discomfort, and pain medications can be prescribed to alleviate their discomfort during the treatment process.
Surgical Procedures
In some cases, surgical procedures may be necessary to remove kidney stones in dogs. Surgery is often recommended when the stones pose a high risk of blocking the urethra, which can be life-threatening. Common surgical procedures for kidney stones in dogs include:
-
Lithotripsy: This surgical procedure involves using laser energy or ultrasound to break the stones into smaller pieces, making them easier to pass through the urinary tract.
-
Surgical Stone Removal: In cases where the stones cannot be effectively treated with less invasive methods, surgical removal of the stones may be necessary. This procedure is typically performed under general anesthesia and requires an incision to access and remove the stones from the urinary tract (Wag Walking).
It’s important to note that the choice of treatment for kidney stones in dogs depends on the size, location, and composition of the stones, as well as the overall health of the dog. Your veterinarian will evaluate these factors and recommend the most appropriate treatment plan for your dog’s specific situation.
After the treatment, regular monitoring of lab tests for kidney function and urine quality is essential to ensure the stones are not causing complications and to detect any recurrence. Imaging rechecks with radiographs or ultrasound may also be necessary to monitor for stone growth or other issues (Pet Health Network). Following your veterinarian’s guidance and maintaining a proper diet and hydration routine can help prevent the formation of new stones and support your dog’s long-term kidney health.
Diet Considerations for Managing Kidney Stones
When it comes to managing kidney stones in dogs, diet plays a crucial role in preventing their formation and recurrence. There are specific dietary considerations for different types of kidney stones that can help dissolve or prevent the formation of stones. Let’s explore two important aspects: prescription diets for dissolution and nutritional approaches for specific stone types.
Prescription Diets for Dissolution
While some types of kidney stones cannot be dissolved through dietary means, others can benefit from prescription diets that aim to prevent their recurrence. Let’s take a look at some specific stone types and their corresponding dietary recommendations:
-
Calcium Oxalate Stones: Dissolution of calcium oxalate stones is not possible through diet alone. However, once the stones have been removed, it’s crucial to prevent their recurrence. Veterinary therapeutic diets marketed to reduce the recurrence of calcium oxalate stones contain modified amounts of calcium to reduce the calcium excreted in urine. These diets also aim to lower oxalic acid in the urine. Consulting with your veterinarian and following their recommendations for the appropriate diet is essential in managing calcium oxalate stones.
-
Purine Stones: Dissolution of purine stones may be possible with protein-restricted therapeutic nutrition combined with additional measures. This includes increasing water intake and urine production, creating an alkaline urine pH, eliminating any existing urinary tract infection, and giving a medication called allopurinol. The same plan is used to reduce purine stone recurrence once the stones have been removed or dissolved. Your veterinarian will guide you on the appropriate diet and treatment plan for managing purine stones.
-
Calcium Phosphate Stones: Dissolution of calcium phosphate stones has not proven to be effective. Prevention involves feeding wet versus dry food, limiting sodium intake, managing urine pH, and additional medication as prescribed by your veterinarian. However, there are no specific diet recommendations for calcium phosphate stones (VCA Hospitals). Your veterinarian will provide guidance on managing calcium phosphate stones based on your dog’s specific needs.
-
Cystine Stones: Dissolution of cystine stones may be possible using a protein-restricted therapeutic food with a controlled sodium level that supports an alkaline urine pH. Your veterinarian may also prescribe potassium citrate to alkalinize the urine and tiopronin to bind to excess cystine and remove it from the body (VCA Hospitals). Working closely with your veterinarian is crucial for managing cystine stones and following the appropriate dietary recommendations.
Nutritional Approaches for Specific Stone Types
In addition to prescription diets for dissolution, nutritional approaches are also important for managing specific types of kidney stones. Here are some examples:
- Struvite Stones: Struvite stones in dogs are commonly associated with bacterial infections in the bladder and can usually be dissolved with specific diets that have reduced levels of protein, magnesium, and phosphorus, increased levels of salt, and create acidic urine. Examples of good options include Royal Canin Veterinary Diet Adult Urinary SO, Hill’s Prescription Diet s/d or c/d Multicare, and Purina Pro Plan Veterinary Diets UR Urinary Ox/St. It’s important to consult your veterinarian to determine the most appropriate diet for managing struvite stones in your dog.
It’s worth noting that each dog’s nutritional needs may vary based on their specific condition and overall health. Therefore, it’s essential to work closely with your veterinarian to determine the most appropriate diet and nutritional approach for managing kidney stones in your dog. Regular monitoring and follow-up care, including lab tests and imaging, will help assess the effectiveness of the chosen diet and ensure long-term management strategies are in place (PetMD). For information on surgical options, refer to our section on dog kidney stones surgery.
By following a tailored diet plan, you can help manage and prevent the recurrence of kidney stones in your beloved canine companion. Remember to consult with your veterinarian, adhere to their recommendations, and provide your dog with the necessary care and support throughout the process.
Monitoring and Follow-Up Care
To effectively manage kidney stones in dogs, it is essential to establish a monitoring and follow-up care plan. This includes regular lab tests and imaging procedures to ensure the ongoing health and well-being of your furry friend.
Lab Tests and Imaging
Regular monitoring of lab tests is crucial for dogs with kidney stones, even if the stones are not causing active infection or blockage. These lab tests help evaluate kidney function and the quality of urine. By monitoring these parameters, veterinarians can assess the effectiveness of the treatment plan and make any necessary adjustments.
Common lab tests for monitoring kidney stones in dogs include:
-
Blood tests: These tests help evaluate kidney function by measuring blood urea nitrogen (BUN) and creatinine levels. Elevated levels may indicate impaired kidney function or a blockage caused by the stones.
-
Urinalysis: This test examines the urine for the presence of crystals, blood, or signs of infection. It provides valuable information about the overall health of the urinary tract and can help identify any underlying issues contributing to stone formation.
Imaging procedures, such as radiographs or ultrasound, are also necessary to monitor the condition and prevent complications. These procedures help visualize the stones, assess their size and location, and monitor for any growth or recurrence after treatment. Regular imaging rechecks are essential to ensure that the stones are not causing complications and to track the progress of the treatment plan.
Long-Term Management Strategies
Managing kidney stones in dogs requires a comprehensive long-term approach. In addition to diet and medication, several strategies can help prevent stone growth and maintain urinary tract health:
-
Dietary Modifications: Depending on the type of stones present, specific dietary modifications may be recommended. For example, in the case of calcium oxalate stones, reducing oxalate intake while ensuring adequate calcium intake is often advised (National Institute of Diabetes and Digestive and Kidney Diseases). The right diet can help control urine pH, reduce crystal formation, and prevent stone recurrence.
-
Increased Water Intake: Adequate hydration is essential for maintaining urinary tract health and preventing stone formation. Encouraging your dog to drink plenty of water can help dilute urine and flush out potential stone-forming substances. Consider providing fresh, clean water at all times and incorporating wet food into their diet to increase water intake.
-
Medication: In some cases, medication may be prescribed to manage underlying conditions or prevent recurrent stone formation. Your veterinarian will determine the appropriate medications based on the specific needs of your dog.
By implementing these long-term management strategies, regular monitoring, and follow-up care, you can ensure the well-being of your dog and minimize the risk of complications associated with kidney stones. Keeping a close eye on your dog’s health and working closely with your veterinarian will help maintain their urinary tract health and overall quality of life.
