❓ Frequently Asked Questions About Pet Urinary Stones
Struvite stones (Magnesium Ammonium Phosphate) form in alkaline urine (high pH) due to urinary tract infections and CAN BE DISSOLVED through acidifying diets. In contrast, Calcium Oxalate stones form in acidic environments and CANNOT be dissolved—they require surgical intervention or ultrasound lithotripsy.
When urine volume increases, the concentration of all mineral ions (Calcium, Magnesium, Phosphate, Oxalate) becomes diluted and drops below saturation threshold (Relative Super Saturation - RSS < 1.0), preventing them from crystallizing. This is the simplest and most effective medical principle.
Dogs with Struvite stones need urine pH acidified to 6.0-6.3. At this pH, Struvite stones gradually dissolve within 3-12 weeks. Veterinary diets like Hill's c/d and Royal Canin S/O are specifically formulated to safely achieve this pH level.
It depends on stone type. For Oxalate stones, limit animal protein as it produces more uric acid and oxalate. For Struvite stones, restrict Magnesium and Phosphate found abundantly in organ meats and dairy products. Consult your veterinarian to identify the exact stone type through testing.
High-Oxalate vegetables to completely avoid: spinach, beets, chocolate, and nuts. Safe vegetables to feed: carrots, broccoli, cucumber, and pumpkin. High-dose Vitamin C should also be avoided as it metabolizes into Oxalate.
Veterinary studies confirm that both dogs and cats tend to drink 40-50% more water when using flowing water fountains compared to still water bowls. The continuous flow also prevents bacterial growth, keeping water cleaner and more appealing.
Go immediately if: your dog cannot urinate at all (complete urinary blockage—this is life-threatening); urinating bright red blood; crying in pain while urinating; abnormally distended abdomen; vomiting with urinary blockage. Especially dangerous in male dogs due to narrower urethras that block more easily.
Not recommended. Prescription diets are clinically researched with precise RSS (Relative Super Saturation) values for each stone type. Self-adjusting diets may dissolve one stone type but inadvertently create conditions for another stone type to form, causing more complications.
