Struvite stones in dogs are mineral obstructions that form in the canine urinary tract. They are often caused by improper diet or pre-existing urinary tract infections. Female dogs are more prone to struvite stones than are male dogs.
Struvite stones can be life-threatening if they interfere with urination and require veterinary attention. Symptoms include pain while urinating, bloody urine or other changes in bathroom behavior. Treatments for struvite stones include low-protein, low-mineral and low-pH diets, antibiotics to treat pre-existing bladder infection, removal via catheter or surgical removal. Struvite stones are more likely to require surgery in male dogs because they are more difficult to pass naturally and more likely to produce a life-threatening obstruction.
