What Foods Cause Bladder Stones in Dogs

Dogs, like people, may grow stones. Diet is an important aspect in treating dog bladder stones. Here, we’ll discuss the finest urinary dog food for dogs with urinary crystals, as well as the best treatments for bladder stones in dogs. If your dog has crystals in his urinary tract, this article outlines the basics of nutrition for dogs with crystals and optimum feeding techniques.

What Is Bladder Stones?

Bladder stones are mineral-rich stone formations that occur in the urinary bladder. A single huge stone or a group of stones ranging in size from gravel grains to sand-sized particles may be present. It’s not uncommon to find a blend of little and huge stones.

What Causes Bladder Stones in Dogs?

While struvite stones in dogs are primarily caused by infection, the remainder of the stones are caused by metabolic disorders (such as liver illness or excessive blood calcium), nutritional imbalances from food and supplements, or genetic diseases passed down from the parents of the dog.

Signs and Symptoms of Stones

Signs and Symptoms of Stones

Dog kidney stones symptoms include when the dog has trouble urinating. Going to the toilet becomes difficult because of stones in the bladder that cause it to expand and become irritated, or because the stones block the bladder, preventing urine from passing through to the urethra and being released. Another indicator that your dog may have stones is when there is the presence of blood in the urine. This occurs when the stones scrape against the bladder wall so the crystals in dog urine, cause discomfort, bleeding, and injury. If you notice anything strange about your dog’s bathroom habits, such as blood in their pee, contact your veterinarian right once.

How to Treat Bladder Stones in Dogs

A technique on how to get rid of bladder stones in dogs is through surgery, which is usually the sole choice when the stones are large and numerous. It’s also the preferred procedure for removing stones in male dogs since the stones are more likely to cause blockage and injury to the bladder. Surgery does not always eliminate all remnants of the stones, which is why, after surgery, veterinarians will ‘flush’ the kidneys to eliminate any remaining evidence. However, even after flushing, it is often hard to remove all of the stones, thus some remnants of the stones may remain.


Stones that are small in size can be eliminated by just flushing (and there are not a lot of them).The third way is through performing a cystoscopy, in which a cystoscope is inserted up through the urethra and into the bladder to start breaking down the stones, which can also be used to remove them. This results in stone particles that are tiny enough to pass through the pee naturally. Again, this approach will only work if the stones are tiny and few. Your veterinarian will go through the many alternatives with you to determine which is best for your dog.

Types of Bladder Stones in Dogs

Types of Bladder Stones in Dogs

Struvite Stones

One of the most prevalent forms of bladder stones in dogs is struvite. Struvite crystals in dogs are solid mineral deposits formed when magnesium and phosphate bind together in the urine. Struvite stones are most commonly found in urine contaminated with ammonium-producing microbes in dogs. This causes the struvite crystals to cluster together and form a stone by raising the pH of the urine. Thus, acidic food is needed to balance the high alkaline pH of the urine.

Calcium Oxalate Stones in urine of the dogs

Calcium Oxalate Stones

When two compounds in urine, calcium and oxalic acid, join together, these stones develop. When the pH of the urine is excessively acidic, the two bond to produce a substance known as calcium oxalate. Because this substance can’t be decomposed or expelled, it becomes stuck in the bladder

bladder stones in urine and urate stones

Urate stones

Bladder stones are mineral-rich rock-like structures that grow in the urinary bladder and are more prevalent in dogs than kidney stones. A single huge stone or a group of stones ranging in size from sand-like granules to pebble sizes may be present. The most prevalent cause of uric acid bladder stones is a genetic mutation that creates a malfunction in the uric acid metabolism.

How to prevent bladder stones in dogs is a question normally asked and the answer is through the dog’s diet. Nutritional treatment for Struvite Stones, Calcium Oxalate Stones, Urate stones:

Acidic foods need to be fed for dogs with struvite stones and avoid alkaline foods for struvite stones. Feed your dog an acidic diet with animal-based protein sources. This will assist in maintaining the acidity in your pet’s urine, which is required to prevent the formation of struvite crystals. Reduced-fat cottage cheese, eggs that are hardboiled, cooked brown rice, and chicken fats are all examples of homemade cuisine. You may replace the cottage cheese with tuna in water or cooked thin minced beef, and the rice with potatoes or noodles. If your veterinarian agrees, you can add raw or lightly boiled vegetables like carrots to boost the nutritional value.

For dogs with Calcium Oxalate Stones, Low oxalate foods need to be eaten. Incorporate items with reduced oxalate levels into their diets, such as peeled apples, white grains, meats, and fish. It’s also a good idea to boil veggies and then drain the water before feeding them to your dog since this reduces the amount of oxalate in them.

For Urate stones, it’s best to feed low and medium-purine foods. When dogs digest purine, the body creates uric acid as a waste product. The formation of uric acid crystals in the joints can lead to a variety of health problems. Chicken, beef, lamb, and non-acidic fruit, for example, have low amounts.

food types that cause crystals in dog urine

What foods cause crystals in dog urine

  • Avoid giving foods that are high in oxalates, such as greens like spinach, yams, organs from meat, and brown rice, to your dog to reduce the risk of bladder stones.
  • Avoid high purine foods. Do not give your dog a vegetarian or cereal-based diet as you want to avoid alkaline urine, which stimulates the formation of struvite crystals.
  • Avoid alkaline foods for struvite stones. Struvite crystals cannot develop in acidic urine because they require an alkaline pH to develop.

Some forms of bladder stones in dogs can be prevented and treated with a properly tailored raw food diet. The incorrect meals, on the other hand, might aggravate your pet’s illness.
