Canine bladder stones, also referred to as uroliths or urinary stones, are solid aggregations of minerals that form within the urinary tract, predominantly in the bladder or urethra of a dog. If left unaddressed, these stones have the potential to induce considerable discomfort and potentially lead to severe health complications.


What are Bladder Stones in Dogs?


Bladder stones are concretions of minerals that develop in the bladder or urethra of dogs, commonly arising from the crystallization of substances like calcium oxalate, struvite, and urate.

These crystals tend to aggregate, progressively increasing in size and consolidating into stones that vary in dimension from minuscule particles to larger, more obstructive structures. Once these stones reach a certain size, they have the potential to impede the passage of urine through the urinary tract, resulting in discomfort, pain, and possible complications such as urinary tract infections or renal impairment.

Timely identification and management of bladder stones are paramount in averting these complications and safeguarding the health of dogs.


What are the Types of Dog Bladder Stones?

Various types of bladder stones impact dogs, including calcium oxalate, struvite, and urate stones, each possessing unique characteristics and etiologies.


What are the Most Common Types of Bladder Stones in Dogs?


“Struvite is the most common type of dog bladder stone, accounting for 37% of found stones, followed by calcium oxalate and uric acid stones at 27% and 27% respectively,” according to the 2017 study by Hoxha, Z.

Struvite Stones in Dogs


Struvite stones typically develop in the presence of urinary tract infections and consist of magnesium, ammonium, and phosphate (Palma, D., et al., 2013).

If there is a urinary tract infection, an optimal environment is created for the colonization of specific bacteria that generate urease. Urease catalyzes the breakdown of urea into ammonia and carbon dioxide, resulting in an alkaline pH level in the urine. This alkaline milieu fosters the formation of struvite crystals, which aggregate to form stones.


Consequently, addressing the underlying urinary tract infection is imperative in preventing the reoccurrence of struvite stones. Neglecting to treat the infection leads to the continual production of struvite stones, potentially resulting in complications and recurrent infections.


Calcium Oxalate Stones in Dogs


Calcium oxalate stones represent one of the most prevalent types of bladder stones detected in dogs, predominantly comprised of calcium crystals.

These stones can potentially materialize when an excessive amount of calcium and oxalate is present in the urine, thereby fostering crystal formation. Various factors, including genetic predisposition, age, and specific medical conditions, also play a role in the genesis of calcium oxalate stones.


Diet and hydration stand out as pivotal influencers in the creation of these stones. A diet rich in oxalate-laden foods such as spinach, rhubarb, and nuts elevates the susceptibility to stone formation. Conversely, optimal hydration levels mitigate the risk of calcium and oxalate concentration in the urine, thereby diminishing the probability of stone development.


“Dietary changes should consider reducing both calcium and oxalate levels to reduce the risk of calcium oxalate formation in dogs,” according to the 2003 study by Stevenson, A., et al. 

What are the Less Common Types of Bladder Stones in Dogs?


Aside from struvite and Calcium Oxalates, dogs can also suffer from urate stones, cystine stones, and silica stones. 


“Struvite, calcium oxalate, urate, and cystine stones are commonly found in dogs' bladder and urethra,” according to the 2012 study by Syme, H.

Silica “jack-stone” uroliths are relatively uncommon and are associated with the ingestion of certain foods high in silicates, such as corn gluten feed and soy hulls (Osborne, C., et al., 1981).


What are the Common Symptoms of Dog Bladder Stones?

The treatment options for canine bladder stones encompass a spectrum of approaches, from conventional medical and surgical methods to holistic strategies incorporating dietary modifications and natural remedies.


Can Medication and Surgery Treat Bladder Stones in Dogs?

Yes. Bladder stones are commonly treated through medication and surgery, particularly in cases where the stones cause significant obstruction or cannot be dissolved through dietary modifications alone. Medication therapy, such as potassium citrate or penicillamine, is utilized to dissolve specific types of bladder stones by modifying the chemical composition of the urine, thereby reducing the propensity for stone formation.


In instances where the stones are of considerable size or do not respond to medication therapy, surgical intervention is necessary. Diagnostic tools such as x-rays, ultrasounds, and urinalysis play an essential role in determining the size, location, and composition of the stones, facilitating the development of a customized treatment plan aimed at effectively managing the condition.


What are the Holistic Approaches for Dog Bladder Stones?


Comprehensive strategies for managing bladder stones in canines emphasize dietary adjustments, adequate hydration, and the utilization of natural interventions such as herbal supplements and acupuncture.


Dietary modifications are pivotal in the prevention of bladder stone development, as they regulate mineral concentrations in the urine. Optimal hydration levels are vital for toxin elimination and the mitigation of stone formation risks.


Natural remedies, such as cranberry supplements, foster an unfavorable milieu for urinary tract stone formation. 


“Dietary supplementation with cranberry may provide some protection to female dogs against uropathogenic E. coli adhesion to urinary epithelial cells,” according to the 2023 study by Carvajal-Campos, A., et al.

Additionally, holistic veterinarians advocate for acupressure to enhance energy flow and support overall bladder well-being.

The prevention of bladder stones in dogs necessitates the maintenance of a balanced diet, ensuring adequate hydration, and the regular monitoring of urinary pH levels.


Can Dietary and Lifestyle Changes Prevent Bladder Stones in Dogs? 


Yes. It is imperative to implement dietary and lifestyle modifications to prevent the formation of bladder stones in dogs. This includes offering a well-balanced diet and promoting regular physical activity.


A balanced diet that is abundant in nutrients sourced from lean proteins, fruits, and

vegetables plays a critical role in maintaining optimal pH levels in the urine. This, in turn, helps decrease the likelihood of bladder stone development. Furthermore, ensuring that dogs stay adequately hydrated by consuming ample water throughout the day assists in flushing out minerals that contribute to the formation of stones.


Regular physical activity is not only beneficial for weight management, a risk factor for bladder stones but also supports overall urinary tract health by facilitating proper circulation and muscle tone.


Holistic Care for Dogs with Bladder Stones

Natural Remedies and Supportive Care for Dog Bladder Stones


Natural remedies and supportive care, such as the utilization of cranberry juice, young coconut water, apple cider vinegar, coconut oil, and essential oils, play a significant role in the management of inflammation and the promotion of bladder health in dogs with bladder stones.


“Medicinal plants can effectively treat urolithiasis in dogs by controlling inflammation, increasing diuresis, preventing crystal aggregation, and favoring their elimination through the urethra,” according to the 2021 study by Rocha, C., & Granato, A. 

Cranberry juice has demonstrated efficacy in inhibiting the formation of bladder stones by creating an environment less conducive to their development. Coconut oil, known for its antibacterial and anti-inflammatory properties, assists in the reduction of inflammation within the bladder. Furthermore, apple cider vinegar is a popular remedy that contributes to overall bladder health by potentially balancing pH levels. When appropriately applied and diluted, essential oils can offer natural relief for symptoms associated with bladder stones. Homeopathy is also gaining recognition for its holistic approach to supporting the body's natural healing processes.
