Struvite Urolithiasis in Dogs: Welfare and Dietary Management

Welfare guide to struvite bladder stones in dogs -- a common, painful, and manageable condition.

Key Facts

Struvite uroliths (bladder stones) are one of the most common urinary tract conditions in dogs
In dogs, struvite stones are typically infection-induced rather than metabolic as in cats
Clinical signs include frequent urination, blood in urine, straining, and abdominal pain
Urinary obstruction from stones is a life-threatening emergency requiring immediate treatment
Treatment options include dissolution diets, medical management of infection, and surgical or endoscopic removal
Struvite stones can dissolve with prescription dissolution diets if bacterial infection is controlled
Prevention involves treating urinary infections promptly and dietary management after stone removal
Regular urine testing detects recurrence early before welfare impact is severe

Welfare Significance

Struvite urolithiasis causes significant urinary discomfort and in cases of obstruction, life-threatening pain and distress. Early detection and prompt treatment prevents escalation from discomfort to emergency. Dietary and infection management after resolution prevents recurrence and protects long-term welfare.

What You Can Do

Seek veterinary assessment for any dog showing urinary signs -- blood, straining, or frequent urination
Complete the full antibiotic course for urinary infections even if signs resolve early
Feed a dissolution diet as directed -- dissolving stones avoids surgery and its welfare risks
Monitor urine pH and recheck cultures after stone dissolution to confirm resolution
