Crystals in the Urine

What are crystals in urine?

Crystals are the basis of bladder stones. However, the presence of crystals does not guarantee that bladder stones will develop. There may be crystals in the urine of healthy dogs. In addition, crystals are a risk factor for kidney stones.

The identification of urine liquid crystals is very important, because certain types of crystals can indicate certain underlying diseases. Identification can help discover diseases that make dogs susceptible to kidney stones. Certain breeds of dogs are more sensitive to urine liquid crystals: Miniature Schnauzers, Yorkshire Terriers and Miniature Poodles are very sensitive to calcium oxalate.

Crystals are a concentrate of natural minerals in dog urine. Different types of crystals can cause different types of bladder stones: magnesium ammonium phosphate (struvite), calcium oxalate, ammonium urate or uric acid, cysteine, calcium phosphate and silicon dioxide.

Symptoms of crystals in dog urine

In many cases, your pet will not show any symptoms of crystals in the urine. However, if the crystals develop into stones, you may see the following symptoms of bladder stones:

  1. thirst
  2. Frequent urination
  3. Trouble urinating

Different mineral concentrations can form different types of crystals. Types of urine liquid crystals include:

Magnesium Ammonium Phosphate
Calcium oxalate
Ammonium Urate
Cysteine
Calcium phosphate
Silica
Uric acid

Causes of crystals in urine

Crystals in dog urine can be caused by one of the following:

Foods high in grains.
Urine pH is not balanced.
The concentration of certain minerals in the urine is abnormal.
Lack of the solubility of crystalline substances in urine.

Diagnosis of crystals in dog urine


The presence of crystals will be determined by urinalysis. The pH of your dog’s urine will be tested and its mineral content will be analyzed.

It is usually found that there are crystals in the urine, so you have reason to suspect that there are stones, and you can also perform X-ray or ultrasound to find the stones.

Treatment of crystals in dog urine

The presence of crystals in dog urine does not necessarily mean that your dog needs medical treatment. Crystals in dog urine are a normal part of the dog’s metabolism. However, a large number of crystals over a long period of time can form blockages and cause stones. In some cases, this requires adjusting the pH of the dog’s urine. For example, struvite crystals are managed by making urine more acidic, and calcium oxalate crystals are managed by making urine more alkaline.

In the above cases, the pH of urine can be adjusted through drugs or diet. In any case, I suggest increasing the dog’s drinking water to increase urine output. This can reduce urine concentration and quickly dissolve crystals. Many prescription diets have added sodium to increase thirst.
