Symptoms and Diagnosis of Canine Oxalate Stones

Urinary stones in dogs – whether calcium oxalate stones or cystine stones – can go unnoticed for a long time. Common symptoms of urinary stones include:

• Frequent urination in small amounts
• Pain during urination (the dog yelps or hesitates when urinating)
• Blood in the urine (hematuria)
• Incontinence or sudden urge to urinate
• Increased licking of the genital area
• Colicky abdominal pain with blocked urinary tracts

Diagnosis is usually made by:

• Urine analysis (pH value, crystals, blood, bacteria)
• Ultrasound or X-ray to visualize the stones
• Stone analysis after removal to precisely determine the composition

Important: The therapeutic and nutritional approach differs depending on the type of stone.

Urinary stones are more common in dogs than often thought – especially calcium oxalate stones pose a constant burden for many animals. However, a targeted nutritional adjustment can significantly reduce the risk of these stone formations. It is important to keep an eye on the urine pH value and ensure a balanced intake of certain minerals.

Types of Canine Urinary Stones

Urinary stones can have different causes depending on their composition. The most important types:

• Struvite stones: develop in an alkaline environment (pH > 7), bacterial cause, urine-acidifying diet recommended
• Calcium oxalate stones: develop in an acidic environment (pH < 6.5), cannot be dissolved, urine-alkalizing feeding recommended
• Urate stones: genetic, e.g., in Dalmatians, low-purine diet necessary
• Cystine stones: genetic, especially in male dogs, reduced-protein and urine-alkalizing diet useful

Diet to Reduce Oxalate Stone Formation

Calcium oxalate stones in dogs usually form with overly acidic urine and increased concentrations of calcium and oxalic acid. The aim of the diet is to minimize the excretion of these substances and to increase the urine pH.

Important measures:

• Low calcium content
• Low vitamin D content to reduce calcium absorption
• Urine-alkalizing properties for pH elevation (pH > 7)

🟩 Urine-alkalizing minerals:

• Calcium: – paradoxical, but important in adapted doses
• Magnesium
• Potassium
• Sodium

🧠 These cations are alkaline, buffer acids, and help raise urine pH – essential for preventing oxalate stones in dogs.

BugBell: Dog Food for Oxalate Stones

A few BugBell products incorporate all measures to reduce oxalate stones. The recipes are based on current nutritional recommendations:

• Low calcium content
• Low vitamin D content
• Urine-alkalizing formula for pH stabilization (pH value above 7)
• Adapted mineral ratios: Calcium, Potassium, Sodium, Chloride

Note: Our products are complete foods with a specifically coordinated composition for nutritional support in cases of urinary stone problems in dogs. It is not a substitute for veterinary treatment.
