Bladder stones are a painful and common urinary tract condition in dogs that can cause discomfort, difficulty urinating, and infections. Managing your dog’s diet plays a vital role in treating bladder stones, preventing recurrence, and supporting overall urinary health.
This in-depth guide covers everything you need to know about the best foods for dogs with bladder stones, hydration tips, foods to avoid, and natural support options—all backed by veterinary expertise.
Understanding Bladder Stones in Dogs
Bladder stones, also called urinary calculi, form when minerals in your dog’s urine crystallize and aggregate inside the bladder. The most common types of stones include:
-
Struvite stones: Often linked to urinary tract infections and alkaline urine.
-
Calcium oxalate stones: Usually form in acidic urine and tend to be harder to dissolve.
-
Urate stones: Associated with genetic predispositions or liver dysfunction.
These stones can cause symptoms such as straining to urinate, blood in urine, frequent urination attempts, and pain. Proper diet management is essential for dissolving some stones and preventing new ones from forming.
Why Diet Is Crucial for Dogs with Bladder Stones
Diet influences the mineral balance and pH level of urine, both key factors in stone development. Feeding the right diet helps:
-
Control levels of minerals like magnesium, phosphorus, and calcium.
-
Maintain urine pH within a range that discourages stone formation.
-
Promote hydration to dilute urine and flush out crystals.
-
Support overall urinary tract and immune health.
What to Feed Your Dog with Bladder Stones
1. Prescription Urinary Diets: The First Line of Defense
Veterinarians often recommend specialized prescription diets formulated to manage bladder stones. These diets are designed to:
-
Limit minerals that contribute to stone formation (magnesium, phosphorus, calcium).
-
Adjust urine pH to dissolve struvite stones or prevent calcium oxalate stones.
-
Increase moisture content to support urinary dilution.
Popular options include Hill’s Prescription Diet c/d Multicare, Royal Canin Urinary SO, and Purina Pro Plan UR St/Ox. It’s important to feed these diets exclusively under veterinary supervision [1].
2. Wet Food vs. Dry Food: Why Moisture Matters
Feeding wet canned food is beneficial because it increases your dog’s fluid intake, helping dilute urine and reduce crystal concentration. If feeding dry kibble, consider adding fresh water or low-sodium broth to boost hydration [4].
3. Homemade Diets: A Balanced Approach with Veterinary Guidance
Balanced homemade meals can be effective when carefully formulated to control mineral intake and maintain appropriate urine pH. Include:
-
Lean, cooked proteins like chicken or turkey (unseasoned).
-
Easily digestible carbohydrates such as white rice or sweet potatoes.
-
Low-oxalate vegetables like green beans and carrots.
Before switching to homemade diets, consult a veterinary nutritionist to ensure complete and balanced nutrition [2].

4. Foods to Avoid for Dogs with Bladder Stones
Avoid feeding your dog the following:
-
Excess dairy and bones (high in calcium).
-
Organ meats such as liver (high phosphorus).
-
Spinach, beet greens, and other high-oxalate vegetables if calcium oxalate stones are present.
-
Nuts, wheat bran, and other magnesium-rich foods.
-
Salty, processed human foods and artificial treats [3].

5. Hydration: The Most Important Factor
Encouraging your dog to drink plenty of water is critical. Tips to increase hydration include:
-
Providing fresh, clean water at all times.
-
Using pet water fountains to stimulate drinking.
-
Adding water or low-sodium broth to food.
-
Feeding moist canned food regularly [4].
6. Natural Supplements: Use Cautiously
Supplements like cranberry extract, omega-3 fatty acids, and probiotics may support urinary tract health but should only be used under veterinary guidance. Explore our detailed guide on Diatomaceous Earth for Dogs for natural support options.
When to Seek Veterinary Care
If your dog shows symptoms like difficulty urinating, blood in urine, frequent urination attempts, or signs of pain, consult your veterinarian immediately. Some bladder stones may require medical or surgical treatment [5].
