The 8 Best Dog Foods for Bladder Stones

1. Royal Canin Urinary Dry Dog Food – Best Overall

Our pick for the best overall dog food for bladder stones is Royal Canin. It is a veterinary-exclusive dry dog food that will support your dog’s urinary health. It increases the amount of urine your dog produces, which dilutes the excess minerals that cause crystals and stones.

It helps to prevent calcium oxalate stones, and this specialized nutrition, along with a reduced level of magnesium, not only helps dissolve struvite stones but will also prevent them from reoccurring. Not only this, but the Relative Super Saturation (RSS) methodology lowers the risk of crystal formation in the bladder by lowering the ion concentration in urine.

The food is expensive but has an added benefit that it is suitable for all breeds and sizes of dogs, and your dog will be a big fan of its tasty chicken flavor.

2. Blue Buffalo Basics Wet Dog Food – Best Value

The best dog food for bladder stones for the money is Blue Buffalo Basics because it is made with all-natural ingredients and is high in nutritional value while supporting your dog’s food sensitivity. As this option does not contain any wheat, it is optimal for dogs who suffer from calcium oxalate stones.

Wet dog food adds interest to dry food or can be enjoyed by itself as a meal or a treat. There is also the added benefit that it injects water into your dog’s diet, which is key in preventing stone formation. However, like many wet foods, it can cause some gas, so beware of those silent but deadly farts!

Blue Buffalo wet dog food contains no chicken or poultry by-products, corn, wheat, soy, dairy, eggs, artificial flavors, or preservatives. As this is a grain-free food, and grains are beneficial to most dogs unless they suffer from an allergy, be sure to check with your vet if this exclusion is necessary for your dog.

While this formula is not specifically made for kidney issues, it is an affordable option that will have the desired effect in helping your dog.

3. Purina Veterinary Dry Dog Food

Purina Veterinary food is perfect for supporting a healthy diet and preventing the formation of stones. It is a great tasting option for your dog’s urinary health and is the result of a nutritionist, researcher, and veterinarian collaboration that has resulted in food that features high-quality and healthy antioxidants for a therapeutic diet for your dog.

It will both dissolve existing struvite stones and prevent the formation of new struvite and calcium oxalate crystals from forming. This diet acidifies urine and has a reduced concentration of the ions and compounds that contribute to the formation of urinary stones.

The large kibble can be a challenge for smaller dogs, however, when moistened with water it will be easier for them to eat.

4. Hill’s Prescription Multicare Dry Dog Food – Best for Puppies

As food plays such a key role in your dog’s overall health and wellbeing Hill’s Urinary Care was developed by nutritionists and veterinarians to help support your dog’s bladder and healthy urinary function. Together they have produced food with a precise balance of magnesium, calcium, and phosphorus to deliver essential nutrition without overloading your dog’s system.

It achieves this by keeping your dog’s urine low in minerals and metabolites which are responsible for creating stones. It prevents struvite stones and offers enough calcium in its diet to prevent oxalate stones. It is also low in sodium which promotes a healthy immune system.

As the kibble is smaller than some other brands, it is ideal for small breeds and puppies to enjoy.

5. The Honest Kitchen Dehydrated Dog Food

The Honest Kitchen offers a diet that controls the levels of minerals and offers good hydration, which is essential for dogs with bladder stones. Not only that, but it is flavor-filled and hassle-free for you! All you need to do is add warm water, and you’ve got a warm, tasty meal ready to go!

6. Hill’s Prescription Urinary Care Dry Dog Food

Nutritionists and veterinarians have developed specially formulated food that provides nutrition to help support your dog’s bladder health, and added antioxidants promote a healthy immune system. The good quality, highly digestible protein, and low levels of calcium in this diet reduce the risk of bladder stones forming.

The added taurine and high levels of L-carnitine also help to maintain a healthy heart muscle function, to keep him happy and active. The small kibble sizes mean it is suitable for dogs of all sizes and breeds. The original flavor can smell like corn and has more of a bland taste than other options.

7. Royal Canin Vet Diet Adult Urinary SO Dog Food

This veterinary-exclusive wet dog food has been developed to nutritionally support your dog’s bladder and urinary tract health. It increases the amount of urine your dog produces, which creates an unfavorable environment for the formation of struvite and calcium oxalate crystals.

RSS methodology lowers the ion concentration in your dog’s urine, which is a contributing factor to stones forming in the bladder. With its reduced level of magnesium, it helps to dissolve struvite stones and prevent them from forming in the future. The texture is in a pate-form, and it is one of the pricier wet dog food options.

8. Grandma Lucy’s Pureformance Dog Food

An excellent way to get extra supplements to improve bladder health into your dog’s diet is by feeding him Grandma Lucy’s pre-mix food which is easy to prepare and freeze-dried. You would pair this with your dog’s favorite protein, and it is packed with fruits and vegetables that will help prevent urate/purine bladder stones.

It is all-natural and rich in natural omega fatty acids that also help maintain a healthy coat, skin, and joints. Because it is pre-mixed it also has the added bonus of saving you time. There are no by-products, preservatives, or GMOs. However, it is grain-free so remember to check with your veterinarian that it is a suitable option. Dogs also might not be overly fond of the texture, which can be mushy thanks to the chickpeas.

How Are Bladder Stones Formed?

Bladder stones develop when minerals that are concentrated in the urine crystallize. Most are made from struvite and calcium oxalate stone, with urate or cystine stones occurring rarely.

A veterinarian will typically prescribe antibiotics, for example, if the diagnosis is struvite stones, and recommend a therapeutic diet that will dissolve the stones and crystals to work alongside the drugs. This could end up being a long-term change for your dog’s diet, so you will want food that not only works but that your dog will enjoy.

The Importance of Diet in Preventing and Managing Bladder Stones

Diet plays a pivotal role in preventing and managing bladder stones in your dog, but how you do this depends on the types of stones your dog has. Specific diets are formed to influence specific factors, like the urine’s pH or the body’s electrolyte and mineral composition. Struvite stones, for example, require a pH that is more acidic to prevent a recurrence. Calcium oxalate prevention requires a diet that dilutes the urine to promote less acidity.

Struvite Bladder Stones

Struvite stones begin when your dog has a bladder infection, so preventing this will hinder this type of stone from forming. Keep your dog’s immune system strong with antioxidants, vitamins, and minerals in your dog’s diet. Keep their water intake up and choose a food with low protein and decreased levels of phosphorus and magnesium as this will promote acidic urine.

Calcium Oxalate Stones

Diets that dilute the urine and contain moderate to low levels of animal protein are recommended. Canned food offers you a higher amount of water, diluting the urine. Try to avoid foods with wheat and organ meat in them as they have high oxalate content.

Urate Stones

Urate stones are not as common and are sometimes referred to as purine stones. They are formed in concentrated or highly acidic urine and are more susceptible in certain breeds because of their DNA. A diet that is lower in meat (as organ meats can form urate stones) and higher in vegetables, with soy protein, and no oats or barley, is ideal for preventing this type of stone.

Cystine Bladder Stones

These types of stones are rare, but when they do occur, they usually do so in male dogs. Choose a diet that promotes diluted urine, which canned or wet food can help with because cystine stones form in acidic urine. Like urate stones, choose a low protein balanced diet (limit the choices of animal meat.)
