🧪 Which Diet is Better for Dissolving Struvite Stones?
Both Royal Canin SO and Hill’s c/d are formulated to manage urinary health and help prevent the formation of struvite stones (which form when urine becomes too alkaline). However, Royal Canin SO is particularly effective at dissolving existing struvite stones, thanks to its ability to acidify urine and promote a low concentration of magnesium and phosphorus, the building blocks of these stones.
Hill’s c/d also works to reduce the risk of struvite stone formation, but it’s primarily designed to prevent recurrence rather than dissolve stones. It promotes a healthy urinary environment by balancing urine pH and controlling mineral content, but it may not dissolve stones as effectively as Royal Canin SO.
| Product | Best for Dissolving Struvite Stones? | Key Function | 💡 Tip |
|---|---|---|---|
| Royal Canin SO 🧪 | Yes, designed to dissolve struvite stones | Acidifies urine and reduces minerals | Ideal for dogs with existing stones ⚠️ |
| Hill’s c/d 🛡️ | Prevents stone recurrence, less focus on dissolution | Maintains balanced pH, reduces recurrence | Best for long-term prevention 🩺 |
🌟 Which Diet Offers More Variety?
If your dog is a picky eater or you prefer variety in texture, Hill’s c/d may be the better option for you. Hill’s offers both dry and wet food, as well as multiple flavor choices, allowing you to cater to your dog’s preferences. This variety can be especially helpful if your dog tends to get bored with their food or if they need a combination of dry and wet textures for dietary balance.
Royal Canin SO, while effective, offers fewer flavor choices and tends to focus more on dry food formulations, though it does provide wet food options as well. However, Royal Canin focuses heavily on the therapeutic benefits of the food rather than flavor diversity.
| Product | Variety | Available Options | 💡 Tip |
|---|---|---|---|
| Royal Canin SO 🌿 | Fewer flavor options, both dry and wet | Focuses more on therapeutic effects | Ideal if health benefits take priority 🌟 |
| Hill’s c/d 🌟 | Offers more flavors and textures | Dry and wet options with variety | Good for picky eaters or mixed feeding 🐾 |
⏳ How Quickly Can I Expect to See Results?
Both Royal Canin SO and Hill’s c/d are designed to improve urinary health within a few weeks of starting the diet. The diets work by reducing mineral concentrations in the urine and promoting an environment less conducive to stone formation.
For dogs with existing struvite stones, Royal Canin SO may work faster, typically dissolving stones within 1-3 months, depending on the size and severity of the stones. On the other hand, Hill’s c/d focuses on long-term management, helping to maintain healthy urine pH and prevent future stone formation, but it might not act as quickly to address current issues.
💡 Tip: Consistency is key—stick to the prescribed diet without additional foods or treats, as even small amounts of non-prescribed food can interfere with the diet’s effectiveness.
| Product | Speed of Symptom Relief | Effectiveness | 💡 Tip |
|---|---|---|---|
| Royal Canin SO ⏳ | Faster for dissolving stones (1-3 months) | Best for quick stone dissolution | Follow up with regular vet checks 🔬 |

🌾 Are Either of These Diets Grain-Free?
Neither Royal Canin SO nor Hill’s c/d are grain-free. Both use grains such as corn and rice as part of their formulation to provide energy and nutrients. These grains are typically not problematic for most dogs, as urinary issues are usually caused by excessive minerals like calcium and magnesium, rather than grain-based ingredients.
If your dog has a grain sensitivity, it’s important to consult your vet for possible grain-free alternatives that still address their urinary health needs. However, for most dogs, these diets are safe and effective without causing additional problems from grains.
| Product | Grain-Free? | Contains Grains | 💡 Tip |
|---|---|---|---|
| Royal Canin SO 🌾 | No, includes corn and rice | Suitable for most dogs | Consult vet if grain sensitivity is a concern 🩺 |
| Hill’s c/d 🌾 | No, includes corn and rice | Safe for most dogs with urinary issues | Check with your vet for grain-free options 🌱 |
💰 Which Diet is More Affordable?
Pricing for Royal Canin SO and Hill’s c/d is relatively similar, though costs can vary depending on the size of the bag or whether you choose dry or wet food. In general, both brands are considered premium prescription diets, so you can expect to pay more than you would for non-prescription foods. That said, you may find Hill’s c/d to be slightly more affordable, particularly for wet food options.
Some veterinarians and retailers offer loyalty programs or rebates for prescription diets, which can help reduce the overall cost, especially for long-term use.
💡 Tip: Consider purchasing larger bags to save on cost per pound, and check with your vet about auto-ship options for potential discounts.

Comment 1: “Can I switch from Hill’s c/d to Royal Canin SO without upsetting my dog’s stomach?”
Yes, you can switch from Hill’s c/d to Royal Canin SO, but it’s crucial to do so gradually to minimize the risk of gastrointestinal upset. Abrupt changes in diet can lead to digestive issues like diarrhea or vomiting. A slow transition over 7 to 10 days allows your dog’s digestive system to adjust smoothly to the new food.
Here’s a simple transition plan:
- Days 1-3: Mix 25% Royal Canin SO with 75% Hill’s c/d.
- Days 4-6: Mix 50% Royal Canin SO with 50% Hill’s c/d.
- Days 7-9: Mix 75% Royal Canin SO with 25% Hill’s c/d.
- Day 10: Feed 100% Royal Canin SO.
💡 Tip: Monitor your dog closely during the transition. If you notice any signs of digestive discomfort, slow down the transition process. Always consult your veterinarian before making significant changes to your dog’s diet.
Comment 2: “Which diet is better for preventing calcium oxalate stones?”
Both Royal Canin SO and Hill’s c/d are formulated to help prevent the formation of calcium oxalate stones. They achieve this by:
- Controlling mineral levels: Both diets have controlled amounts of calcium, oxalate, and other minerals that contribute to stone formation.
- Promoting dilute urine: Increased moisture content and specific ingredients encourage your dog to drink more water, leading to diluted urine that reduces stone risk.
- Optimizing urine pH: They maintain a slightly acidic urine pH, which is less conducive to calcium oxalate stone formation.
💡 Tip: While both diets are effective, Royal Canin SO has a specific focus on promoting increased urine production, which may offer an added benefit in flushing out minerals. Discuss with your vet to determine which diet aligns best with your dog’s specific needs.
Comment 3: “My dog has a grain allergy. Are there grain-free options for urinary health?”
If your dog has a confirmed grain allergy, neither Royal Canin SO nor Hill’s c/d may be suitable, as both contain grains like corn and rice. However, there are grain-free prescription diets formulated to support urinary health. These diets maintain the essential features needed to prevent stone formation, such as controlled mineral content and urine acidification, without including common grains.
💡 Tip: Consult your veterinarian about grain-free urinary diets like Royal Canin Ultamino or Hill’s Prescription Diet u/d, which might be more appropriate for dogs with grain sensitivities while still addressing urinary health.
Comment 4: “Can I feed my healthy dog these urinary diets as a preventive measure?”
Feeding Royal Canin SO or Hill’s c/d to a healthy dog without urinary issues is generally not recommended unless advised by a veterinarian. These diets are specifically formulated to address certain medical conditions and may not meet the nutritional needs of a dog without those conditions.
- Nutrient Levels: The mineral and nutrient levels are adjusted for therapeutic purposes, which might not be ideal for healthy dogs.
- Cost: Prescription diets are often more expensive than regular dog food, increasing unnecessary expenses.
- Medical Supervision: Using these diets without veterinary guidance could mask underlying issues or create nutritional imbalances over time.
💡 Tip: For healthy dogs, stick to a balanced, high-quality commercial diet appropriate for their life stage and activity level. If you’re concerned about urinary health, encourage ample water intake and regular vet check-ups.
Comment 5: “How do these diets affect urine pH, and why is that important?”

💡 Tip: Regular urine testing can help monitor pH levels and ensure the diet is effectively managing your dog’s urinary environment. Discuss with your vet about periodic urine analysis.
Comment 6: “Can these diets help with urinary tract infections (UTIs)?”
While Royal Canin SO and Hill’s c/d are primarily formulated to manage urinary stones, they can indirectly help reduce the risk of urinary tract infections by:
- Diluting Urine: Encouraging increased water intake and urine production, which helps flush out bacteria.
- Optimizing Urine pH: Creating an environment less favorable for bacterial growth.
However, these diets are not a substitute for antibiotics or other treatments prescribed for UTIs.
💡 Tip: If your dog suffers from recurrent UTIs, it’s essential to address the underlying cause with your veterinarian. The diet can be part of a comprehensive management plan but should not be the sole treatment.
Comment 7: “Is it okay to give my dog treats while on these urinary diets?”
Feeding your dog non-prescription treats while on a urinary diet can counteract the benefits of the specialized food. Treats may contain minerals or ingredients that promote stone formation.
Safe Options:
- Prescription Treats: Both Royal Canin and Hill’s offer urinary-friendly treats formulated to complement their diets.
- Vegetables: Small amounts of dog-safe vegetables like carrots or green beans (ensure they’re low in oxalates).
💡 Tip: Always consult your vet before introducing any new treats or snacks. They can recommend suitable options that won’t interfere with your dog’s urinary health.
Comment 8: “How do I choose between Royal Canin SO and Hill’s c/d for my dog?”
Choosing between the two diets depends on several factors:
- Specific Urinary Issue: If your dog has existing struvite stones, Royal Canin SO may be more effective in dissolving them.
- Prevention vs. Treatment: For ongoing management and prevention of stone recurrence, Hill’s c/d is an excellent choice.
- Dietary Preferences: If your dog is a picky eater, Hill’s c/d offers more flavor and texture options.
- Veterinarian Recommendation: Your vet’s advice should be the primary guide, as they understand your dog’s unique medical history.
💡 Tip: Discuss your dog’s specific needs with your veterinarian, considering factors like medical history, dietary preferences, and how quickly you need to see results.
Comment 9: “Can these diets cause any side effects?”
Both diets are generally safe and well-tolerated, but potential side effects may include:
- Digestive Upset: Some dogs might experience vomiting or diarrhea during the initial transition.
- Weight Gain: The palatability of these diets might lead to overeating if portions aren’t controlled.
- Allergic Reactions: Rarely, dogs might be allergic to certain ingredients in the diets.
💡 Tip: Transition your dog gradually to the new diet and monitor their weight and overall health. If you notice any adverse reactions, contact your veterinarian promptly.
Comment 10: “How long should my dog stay on a urinary prescription diet?”
The duration depends on your dog’s specific condition:
- For Dissolving Stones: If using Royal Canin SO to dissolve struvite stones, your dog may need to stay on the diet for several months until the stones are gone.
- Preventing Recurrence: For chronic conditions, your vet may recommend a lifetime dietary management plan with Hill’s c/d or Royal Canin SO.
💡 Tip: Always follow your veterinarian’s guidance on the duration of the diet. Regular check-ups and urine tests will help determine if and when any dietary adjustments are needed.
Comment 11: “Can I mix wet and dry versions of these diets?”
Yes, mixing wet and dry forms of the same diet can be beneficial:
- Hydration: Wet food increases overall moisture intake, promoting urine dilution.
- Palatability: Combining textures can make the meal more appealing to your dog.
💡 Tip: Ensure both wet and dry foods are from the same brand and prescription line to maintain the diet’s therapeutic effectiveness. Adjust portion sizes accordingly to prevent overfeeding.
Comment 12: “Are there any natural supplements that can support my dog’s urinary health along with these diets?”
While the prescription diets are specifically formulated for urinary health, some natural supplements might offer additional support:

- Glucosamine and Chondroitin: Support bladder lining health.
- Probiotics: Promote a healthy gut microbiome, indirectly supporting immune function.
💡 Tip: Always consult your veterinarian before adding supplements, as some may interfere with the diet’s effectiveness or not be appropriate for your dog’s condition.
Comment 13: “What should I do if my dog refuses to eat the prescribed urinary diet?”
If your dog is reluctant to eat the new food:
- Gradual Transition: Extend the transition period to slowly acclimate your dog to the new taste and texture.
- Enhance Palatability:
- Warm the food slightly to release aromas.
- Add a small amount of the wet version to the dry kibble.
- Consistency: Avoid offering alternative foods, which may encourage picky eating.
💡 Tip: If refusal persists, consult your vet. They may suggest an alternative prescription diet or check for underlying issues affecting appetite.
Comment 14: “Can these diets be used for cats as well?”
While both Royal Canin and Hill’s offer urinary diets for cats, the dog formulations should not be fed to cats.
- Nutritional Needs: Cats have unique nutritional requirements, including higher protein levels and specific amino acids like taurine.
- Prescription Options: Both brands offer cat-specific urinary diets like Royal Canin Urinary SO for Cats and Hill’s Prescription Diet c/d Multicare Feline.
💡 Tip: Never feed dog food to cats. Consult your veterinarian for the appropriate feline urinary diet.
Comment 15: “Is it necessary to provide constant access to water while my dog is on a urinary diet?”
Absolutely, constant access to fresh water is crucial.
- Urine Dilution: Ample water intake helps dilute urine, reducing mineral concentration.
- Flush Out Toxins: Increased urination aids in flushing out potential irritants and bacteria.
💡 Tip: Encourage your dog to drink more by:
