1. Hill’s Prescription Diet c/d Multicare Urinary Care Dog Food

  • Helps reduce the risk of both struvite and calcium oxalate stone formation and recurrence
  • Helps dissolve struvite stones
  • Promotes bladder health
  • Balanced fat and sodium levels to support healthy weight
  • Enriched with antioxidants, potassium citrate, and omega-3 fatty acids for healthy immunity

  • Tiny kibble suitable for small-breed dogs
  • Comes in big and smaller bags


  • On the expensive side
  • Requires a veterinary prescription

  • Not a suitable option for dogs with allergies

Hill’s specially crafted formula is our top dry food substitute for Royal Canin Urinary SO since it supports bladder health and is recommended by veterinarians as balanced nutrition for dogs with urinary problems.

The formula helps dissolve struvite stones and reduces the risk of their recurrence.

Also, it lowers the risk of calcium oxalate stone formation and recurrence.

Nutritionists and vets assisted in developing this recipe that can prevent mineral crystals from combining in the urinary tract which leads to more serious problems like stones.

Talking about ingredients, both Hill and Royal Canin SO contain grains – including brewers rice and corn gluten meal to provide energy and fiber to your canine companion, however, Hill includes soybean meal and flaxseed.

Flaxseed is a fantastic source of fiber and omega fatty acids that boost your dog’s digestion, bowel movement, skin, and coat.

Soybean meal is rich in digestible protein that helps your canine build muscle and fight stones.

The two formulas are also enriched with fish oil which is another great source of omega fatty acids to give your pup shiny skin and coat.

Hill’s formula has soybean oil as well, another good source of omega-6 fatty acids that contribute to your pup’s immune function, skin, and coat.

Additionally, Royal Canin’s has corn whereas Hill’s recipe has whole-grain corn which is a healthier source of fiber, antioxidants, and vitamins that strengthen the immune system.

Whole-grain corn is rich in prebiotic fiber too which is beneficial for the gut flora.

Hill’s kibble features better protein sources as well.

It uses chicken meal, chicken fat, and egg product while Royal Canin uses chicken by-product meal.

In comparison, both Hill’s and Royal Canin’s recipes contain 17% crude protein content, but Royal Canin’s has more fat (15 % vs 13 %), and Hill’s has more fiber (6 % vs 3.5 %).

Protein is essential for your dog’s muscles, strength, bones, and immune system and your dog can benefit from high-quality protein from real meat and fish.

Keep in mind that canines with urinary issues should have a diet lower in protein which helps with urinary, bladder, and liver problems.

Fat fuels your dog’s body, but too much fat can cause weight gain, so pups who are overweight should have a diet lower in fat.

Dog parents who avoid by-products will also appreciate Hill’s formula more.

Hill’s c/d Multicare is an excellent choice for adult dogs of any breed who struggle with urinary health problems. Based on discussions on Reddit, this food is also considered beneficial for dogs with diabetes. (To learn more about the best substitutions to Hill’s c/d recipe check out our article Hill’s C/d Dog Food Alternatives).

The combination of premium quality ingredients provides overall health benefits, it also promotes bladder health, dissolves struvite stones, and prevents calcium oxalate stones and you get good value for money.

Blue Buffalo’s team developed a natural wet formula that makes a great alternative to Royal Canin Veterinary Diet Adult Urinary SO Loaf Canned Dog Food.

What makes this delicious food special is the balanced levels of fat and sodium to support a healthy weight and the controlled levels of minerals to promote urinary health.

It’s a terrific choice for adult dogs of any breed with urinary health concerns, but also need to lose some weight.

Moreover, Blue Buffalo’s holistic approach to food and its carefully chosen ingredients give your dog nutrients to stay healthy and strong.

The grain-free recipe features chicken, chicken broth, water, whitefish, and chicken liver as the first 5 ingredients.

Chicken, chicken liver, and whitefish are fantastic sources of protein that help your pup build muscle and stay active and healthy, plus dogs love the taste of these ingredients.

Whitefish is rich in omega fatty acids too that are beneficial for your dog’s skin, coat, and immune system.

Royal Canin’s Loaf also features water and chicken liver, but it has chicken and pork by-products in addition.

Some dog parents avoid by-products and buy food that offers more quality protein.

In fact, Blue Buffalo’s recipe has 7.5% crude protein from real meat whereas Royal Canin’s has 5.6% crude protein content.

The two formulas have powdered cellulose in common, which isn’t a great source of fiber.

However, Blue Buffalo’s recipe is enriched with potatoes, barley, brown rice, oats, and flaxseed which are high in fiber, nutrients, and vitamins that keep your fur buddy full longer and give him healthy skin and coat.

And it contains cranberries which have a positive effect on urinary infections.

Blue Buffalo’s formula is free from wheat, soy, and corn, and pups with food sensitivities can enjoy it too.

In contrast, Royal Canin’s formula has corn and corn starch which can cause stomach and skin problems in some dogs.

So, we recommend Blue Buffalo’s formula as a terrific alternative to Royal Canin for dogs who are sensitive to corn, soy, or wheat and need a grain-free option to avoid upset stomachs and irritations.

Furthermore, Blue Buffalo’s wet food has 2.5% crude fat, and Royal Canin’s more than double the amount, and less fat content is better for dogs with weight problems.

Another significant difference between the two formulas is the fiber percentage.

Blue Buffalo has 5% fiber content while Royal Canin has 1.6%.

Fiber is beneficial for dogs since it promotes digestive health, good bowel movement, and healthy weight.

Last, but not least, Blue Buffalo’s wet formula is incredibly high in moisture (78%) which helps increase water intake and that’s useful for dogs with urinary problems.

Blue Buffalo’s vet-prescribed formula is made with quality ingredients like meat, whole grains, fruits, and veggies, balanced levels of fat, sodium, and minerals that keep your canine healthy, preventing urinary issues, and weight gain.

Note that if your dog doesn’t need to lose weight, it’s better to opt for different food.

Final Thoughts 

Royal Canin Urinary SO has helped many dogs with urinary tract infections (UTI) and many vets recommend it as a therapeutic diet.

But, the food includes wheat, soy, and corn and it isn’t suitable for dogs sensitive to these ingredients.

Our favorite alternative, Hill’s Prescription Diet c/d Multicare Urinary Care Dog Food can aid dogs with urinary problems and offer health benefits to adult dogs of any breed.

The specially made formula has first-rate ingredients that promote bladder health, dissolve struvite stones, and prevent both struvite and calcium oxalate stones.

The other Royal Canin Urinary SO substitutes can help dogs with urinary issues as well and promote digestive, skin, and general health.

Choose wisely and consult your vet before making any decision regarding your dog’s diet.


Determining the best dog food for urinary issues isn’t a straightforward task; it hinges on your dog’s unique health profile. That said, there are some noteworthy alternatives to Royal Canin Urinary SO. Brands like Hill’s Prescription Diet c/d Multicare and Purina Pro Veterinary Diet UR offer specialized formulas that focus on urinary tract health. These options are frequently vet-recommended. However, it’s essential to consult your veterinarian for a tailored recommendation that suits your dog’s specific needs.

While Royal Canin Urinary SO is expertly crafted to bolster urinary tract and bladder well-being in dogs, it’s not a one-size-fits-all solution for kidney disease. If your furry friend has been diagnosed with kidney issues, it’s crucial to consult your veterinarian for specialized kidney care dog food options.

Although Royal Canin Urinary SO is a well-balanced diet suitable for extended use, it’s vital to schedule a vet check-up every 6 months if you plan on feeding this diet to your dog for an extended period. Typically, it’s prescribed for a period ranging from 5-12 weeks to dissolve struvite stones, and up to 6 months to prevent their recurrence.

Royal Canin Urinary SO generally doesn’t come with a list of side effects. However, its primary function is to increase urine output, so don’t be surprised if you find your dog making more frequent trips to the yard. This uptick in urination is a normal response and is integral to the food’s role in promoting urinary health.
