Causes of Urine Crystals

Urine crystals in dogs can be caused by an imbalance of minerals in the body and diet. A diet that contains too much calcium, magnesium and other minerals can lead to the formation of crystals, which can cause bladder and urinary tract infections.

It is important to understand the causes of urine crystals in order to choose the best diet for your dog.

Identify the type of crystals in your dog’s urine

When trying to identify the type of crystals in your dog’s urine, the two most common types are struvite and calcium oxalate crystals. It is important to understand which type of crystal your pup has so that you can make an informed decision on their diet.

  • Struvite crystals are mainly composed of magnesium, ammonium and phosphate, while calcium oxalate crystals are made up of larger particles containing both calcium and oxalic acid.
  • Both types oftentimes form as a result of excess minerals that are present in the urine. This usually occurs when the pH balance is too high or low.
  • Other causes could include an incorrect diet, dehydration and stress related illness.

Knowing exactly what type of crystal your pup has will help you determine an appropriate dietary plan with the right amount of minerals and vitamins needed for optimal urinary health.

Understand the underlying cause of the crystals

Urine crystals are solid formations of minerals, proteins and organic matter which form when the balance between the components within a dog’s urine become imbalanced. When this happens, these materials crystallize and may cause issues with comfort and health. Understanding what causes the crystals is important in establishing a course of treatment.

Common causes of urine crystals include:

  • An inadequate diet,
  • Chronic urinary tract infections, or
  • An environmental change such as reduced water intake or increased stress.

An insufficient diet may lead to a lack of certain vitamins or minerals (such as calcium, phosphorous, magnesium and/or potassium) that help keep the crystals from forming in the first place. Also, diets high in protein can increase urinary acidity which allows stones and crystals to form more readily. In addition to other dietary factors that affect crystallization, dogs who do not drink enough water will be at greater risk for developing urine crystals due to concentration of the urine itself.

Diet Recommendations

Diet plays a crucial role in dogs suffering from urine crystals. An appropriate diet helps to reduce the risk of recurrence and provides a balanced nutritional profile for your pet. We will be discussing the best dietary recommendations for dogs with urine crystals in this article.

Increase water intake

If your dog has been diagnosed with urine crystals, it is important to increase their water intake in order to reduce the amount of crystals that are formed in the urine. To achieve this, it is recommended to:

  • Provide them with fresh water throughout the day and/or consider adding wet food as part of their diet which will help provide additional moisture.
  • If your dog drinks from a water bowl or fountain, make sure to clean and refill these multiple times per day as well.
  • You can also introduce a variety of flavors and crunchy textures to your dog’s water like fruit or vegetable puree or freeze-dried treats which may encourage them to drink more.
  • Lastly, if you take your dog on walks frequently, try bringing a collapsible bowl so that they can stay hydrated outdoors as well.

Reduce dietary protein

Reducing dietary protein is an important step in managing the development of crystals and stones in a dog’s urinary system. Protein contains purines, which are broken down into compounds called uric acid. Excess dietary uric acid makes it easier for stones and crystals to form, so you should look for a low-protein diet that also has moderate phosphorus levels.

It’s important to consult with your vet before changing your pup’s diet to make sure that any new food still provides all the necessary vitamins and minerals for his health. If your pup needs a lower protein diet, you may opt for:

  • Smaller breeds selecting kibble sizes designed specifically for their size.
  • Choosing a diet formulated just for them.
  • High-quality proteins from sources like venison, bison or duck than provide fewer purines than beef or chicken.

Low-protein diets also help reduce the risk of other conditions such as chronic kidney disease, joint issues and metabolic diseases in older dogs.

Increase dietary fiber

Increasing dietary fiber can be an important part of helping to reduce the development of urine crystals in dogs. Dietary fiber can assist by helping to bind the minerals found in urine to make them less available to form crystals. This is due to the fact that it absorbs water and can, therefore, act as a binding agent for these minerals. An increase in dietary fiber may also help reduce inflammation and bloating associated with urinary tract issues, as well as helping with weight management.

It is important to ensure that when increasing dietary fiber you are doing so gradually, as it can cause excess gas and abdominal discomfort if introduced too quickly.

Foods high in dietary fiber include:

  • Sweet potatoes
  • Oats
  • Applesauce
  • Peas
  • Ground flaxseeds

Increase dietary potassium

Increasing the amount of dietary potassium can help reduce the risk of crystal formation in dogs. Potassium is an electrolyte found in many foods, and it helps to balance out levels of sodium and other minerals in the urine. Foods rich in potassium include leafy green vegetables, sweet potatoes, and bananas.

If your pup has a urinary issue related to mineral imbalances, your veterinarian may recommend adding supplementary potassium to their food. Increasing dietary potassium can be beneficial for a variety of other medical conditions as well, including diabetes and high blood pressure.

Always consult your veterinarian before making any changes to your pet’s diet or supplements!


Dietary supplements are becoming increasingly popular for dogs with urinary tract conditions. These supplements can help provide necessary nutrients to improve the overall health of your pup, as well as reduce the negative effects of urine crystals.

Here, we will discuss the benefits of using supplements for your pup’s diet and which ones are most effective:

Consider adding supplements to your dog’s diet

When dealing with conditions such as urinary crystals, adding supplements to your dog’s diet can be an effective way to prevent further issues. Supplements provide an additional source of important vitamins and minerals that may be lacking in the animal’s regular diet. Omega-3 fatty acids, glucosamine and chondroitin, probiotics, and vitamin E are important supplements for dogs that have urine crystals.

  • Omega-3 fatty acids help reduce inflammation, which can help lessen the symptoms of crystal formation in the bladder or kidneys.
  • Glucosamine and chondroitin have been shown to improve joint health and function in dogs with arthritis, which can reduce discomfort due to crystal formation.
  • Probiotics help enhance digestion and absorption of nutrients from food, ensuring your dog is getting all the necessary vitamins and minerals from their diet.
  • Vitamin E is a powerful antioxidant that helps support your pup’s overall health.

Adding these supplements can be a great way to ensure your dog’s urinary health is kept in check on a daily basis without resorting to costly medications or surgery for treatment of crystal formation.

Research the types of supplements that are beneficial for your dog

For dogs with urine crystals, an increased dietary supplement intake may be beneficial. Supplements are an important component of maintaining a diet that supports overall pet health and aids in the prevention and management of many medical conditions.

When researching supplements, be sure to read up on the potential benefits and risks associated with each type. For dogs with urinary tract problems, look for supplements that provide adequate amounts of natural vitamins and minerals, as well as essential fatty acids such as omega-3s, which are known to support a healthy immune system. Antioxidants such as Vitamin E may also help reduce inflammation associated with urinary tract infections or crystals. Additionally, look for probiotics that can help support gut health by replenishing beneficial bacteria populations in the intestines.

Finally, consult with your veterinarian about any other specific supplement recommendations they may have based on your dog’s condition and history.

Other Considerations

Along with a diet that is low in magnesium, there are some other important considerations for dogs with urine crystals. Being informed and proactive about the care of your dog is essential when it comes to their long-term health.

Let’s look at some of the other considerations that should be taken into account when choosing a diet for such dogs:

Monitor your dog’s urine pH

Monitoring your dog’s urine pH is essential when it comes to managing bladder crystals. Urine pH should be monitored both before and after any dietary changes are made. A healthy, balanced diet for dogs with urinary crystals should aim for a urine pH of 6.5 or higher.

If your vet suggests that your dog has a lower than ideal urine pH, there are some dietary options to help raise it and reduce the risk of recurrence of bladder crystals:

  • Add foods high in ash content like cooked chicken or turkey, eggs or fish meal to their diet, as well as feed them a balanced and easily digestible diet that is low in magnesium content.
  • Adding plant-based sources of potassium like sweet potatoes may help naturally raise pH levels and reduce the risk of crystal formation.


After researching and understanding the dietary needs for dogs with urine crystals, we can conclude that reducing the levels of magnesium and phosphorus in the diet is essential for optimum urinary health. A diet high in quality protein and low in simple carbohydrates is recommended, as well as feeding a low sodium diet with adequate hydration.

Furthermore, feeding wet food can be beneficial for urinary health since it adds moisture to the diet.

Summary of the best diet for dogs with urine crystals

For dogs with urine crystals, the best diet for overall health is one that is high in moisture and low in protein. Feeding your dog canned or raw food can help increase the amount of moisture they consume and reduce the amount of processed dry kibble they eat.

Additionally, it’s important to make sure that the food you provide your dog has a balanced ratio of calcium and phosphorus, as well as an appropriate level of magnesium. If needed, supplementing with pumpkin seeds can help reduce the incidence of struvite crystals.

Finally, it’s important to properly hydrate your pet so that their urine has an acceptable pH level—a diet rich in fruits and vegetables can help lower urine pH levels.

By following these guidelines, you can provide your dog with the best diet to promote urinary health and prevent painful crystal formation.
