Dog Bladder Stones: Prevention and Welfare

Urinary bladder stones in dogs cause significant pain and can become life-threatening, requiring dietary management and veterinary intervention to protect welfare.

Key Facts

Struvite and calcium oxalate are the most common bladder stone types in dogs
Signs include blood in urine, straining to urinate, and frequent small urinations
Male dogs face higher risk of urethral obstruction from stones, which is a veterinary emergency
Diet plays a key role in both stone formation and dissolution for certain stone types
Struvite stones often dissolve with prescription dissolution diets; oxalate stones require surgery
Dalmatians, Miniature Schnauzers, and Yorkshire Terriers have higher genetic predisposition

Welfare Considerations

Bladder stones cause persistent pain during urination and risk of life-threatening obstruction. Dogs in pain from urinary disease often show behavioral changes - restlessness, licking at genitals, and reluctance to exercise. Urethral obstruction requires emergency veterinary care and causes intense suffering. Dietary prevention for susceptible breeds and prompt treatment of diagnosed stones are welfare priorities.

What You Can Do

Seek veterinary care immediately if your dog strains to urinate or produces bloody urine
Feed prescription dissolution diet as directed if struvite stones are diagnosed
Increase water intake through wet food or water fountains for stone-prone dogs
Submit all surgically removed stones for analysis to guide dietary prevention
Perform urine pH monitoring and urinalysis twice yearly for breeds at risk
Discuss genetic screening for uric acid stone risk in Dalmatians before breeding
