Crystals in female dog urine can be a source of concern for many pet owners. Crystals can form in a dog's urine due to a high concentration of minerals, specifically struvite and calcium oxalate.
Dogs are more prone to developing urinary crystals if they have a diet high in protein and ash, which can lead to an increased concentration of minerals in their urine. This is especially true for female dogs, as their shorter urethra makes them more susceptible to urinary tract infections and crystal formation.
Some common symptoms of urinary crystals in female dogs include straining to urinate, blood in the urine, and frequent urination. These symptoms can be uncomfortable and even painful for your dog.
Causes and Types of Crystals
Crystals in female dog urine can be caused by several factors. Abnormal urine pH is a common cause, which can be triggered by the presence of bacteria or poor-quality dog food.

Some breeds are more susceptible to certain types of crystals, such as Miniature Schnauzers, Yorkshire Terriers, Lhasa Apsos, and Miniature Poodles, which are prone to calcium oxalate crystals. Dachshunds, English Bulldogs, and Newfoundlands are more likely to develop cysteine crystals.
A diet of highly processed dog food, and/or foods high in grains and other fillers, can also contribute to the formation of crystals. Additionally, certain medications that affect mineral concentrations in urine can cause crystals to form.
Types of Crystals
There are several types of crystals that can be found in a dog's urine, and it's essential to know what they are and how they form.
Struvite and calcium oxalate crystals are the most common types of crystals found in dogs.
Calcium oxalate crystals develop in a dog's urine when the pH level drops below 6.5, indicating high acidity.
Some breeds are more susceptible to certain types of crystals, such as Miniature Schnauzers, Yorkshire Terriers, Lhasa Apsos, and Miniature Poodles, which are prone to calcium oxalate crystals.

Here are the common types of crystals found in dog urine:

Some breeds are more susceptible to certain types of crystals, such as Miniature Schnauzers, Yorkshire Terriers, and Lhasa Apsos, which are prone to calcium oxalate crystals.
A diet of highly processed dog food, and/or foods high in grains and other fillers, can also contribute to the formation of crystals in dog urine. Timing of sample collection can also impact the results, as a sample taken after a meal may have higher concentrations than a sample taken during fasting.
Abnormal concentrations of certain minerals in urine, imbalanced urine pH, and lack of solubility of crystallogenic substances in the urine can all lead to the formation of crystals. Certain breeds, such as Dachshunds, English Bulldogs, and Newfoundlands, are more prone to cysteine crystals, while others, like Miniature Schnauzers, Shih Tzus, and Bichon Frises, are more susceptible to struvite crystals.

Here are some common types of crystals found in dog urine and the breeds most susceptible to them:
A balanced diet, regular check-ups, and plenty of water are essential for preventing and managing crystals in dog urine.
Diagnosis and Monitoring
To diagnose crystals in your female dog's urine, your vet will perform a urinalysis, which involves examining a urine sample under a microscope to check for the presence of crystals and determine their type.
The urine pH and mineral content will also be tested to help identify the type of crystals. Microscopic examination can reveal the type of crystals, which is crucial for effective treatment.
Your vet may also use imaging tests, such as an x-ray or ultrasound, to check for stones (uroliths) that could be causing your dog's symptoms. If stones are present, imaging can help determine their size and number.
After treatment to dissolve the crystals and/or stones, your dog will need regular checkups to ensure the therapy is working. These checkups will typically occur every 4 weeks, and will involve urinalysis, urine culture, and radiographs to monitor the progress of the dissolution.
Crystal Diagnosis Methods

To diagnose urine crystals in dogs, a urinalysis is performed, which involves examining a urine sample under a microscope to identify the crystals.
A urine sample is collected from your dog, and the pH and mineral content are checked to help determine the type of crystals present.
If stones or uroliths are suspected, an x-ray or ultrasound may be done to reveal their size and number.
A microscopic examination of the urine sample can also help identify the type of crystals, which is crucial for proper diagnosis and treatment.
Culture and sensitivity testing may be performed if a bacterial infection is suspected to determine the causative agent and choose the right antibiotic.
Monitoring Your Dog
Monitoring your dog's urine crystals is crucial to their health. Your vet will typically recommend checkups every 4 weeks after therapy to dissolve the crystals and stones.
During these checkups, your vet will perform urinalysis and urine culture to confirm if therapy is still effective. This helps ensure the crystals don't return.
Radiographs will also be taken to monitor the progress of the dissolution. If the stone has dissolved, therapy is usually continued for 2-4 weeks.
A balanced diet, regular check-ups, and plenty of water can help prevent and manage urinary crystals.
Symptoms and Health Issues

Symptoms of crystals in female dog urine can be quite concerning. Frequent urination is a common sign, with your dog taking more bathroom breaks than usual.
Some female dogs may strain to urinate, making it challenging for them to pass urine. This can be a painful and frustrating experience for your pet.
Blood in the urine is a telltale sign of crystals in the urine, with a pink or reddish tint visible in their urine. This is a clear indication that your dog needs veterinary attention.
Painful urination can cause your dog to whimper or show discomfort while peeing. This is often accompanied by licking their urinary area to soothe the irritation.
Here are some common symptoms to look out for:
- Frequent Urination: More bathroom breaks than usual.
- Straining to Urinate: Difficulty passing urine.
- Blood in the Urine: Pink or reddish tint in their urine.
- Painful Urination: Whimpering or showing discomfort while peeing.
- Licking Urinary Opening: Frequent licking of the urinary area.

Common Canine Health Issue?
Urinary crystals in dogs are a common health issue that can be a real puzzle to solve. Some dogs with urinary crystals never show any signs of discomfort or health issues.
Certain dog breeds are more prone to developing urine crystals, which can lead to more severe health issues. Factors such as age, activity level, and overall health may influence the likelihood of urinary crystals.
A balanced diet and regular check-ups are crucial in preventing and managing this issue. Your vet may discover urinary crystals during a routine veterinary check-up, even if your dog isn't showing any symptoms.
Urine crystals can irritate your dog's bladder and urinary tract, making it easier for bacteria to multiply and cause infections.
Ammonium Urate

Ammonium Urate is a type of crystal that can form in your dog's urine due to excess uric acid. Certain dog breeds, such as Dalmatians, are more likely to get these crystals because of their genetic makeup.
Dalmatians are particularly prone to this issue, which can lead to kidney stones and other health problems if left untreated.
Treatment and Diet
Crystals in your dog's urine don't necessarily mean they're experiencing symptoms, but it's still important to consider intervention if they have a history of urinary tract obstruction or struvite urolithiasis.
Dietary management is a crucial part of treatment, and it's recommended to identify the type of crystal and treat any concurrent bacterial infections of the urinary tract.
To prevent crystals from forming, it's essential to feed your dog a diet that's low in protein, magnesium, and phosphorus, and to ensure they drink plenty of water to dilute their urine.
A diet rich in grains and legumes can increase urine pH, making it more likely for crystals to form, while a diet that focuses on meats and organs tends to decrease urine pH.

Dogs that drink enough water, ideally four cups for each cup of kibble, are less likely to develop urine crystals, as frequent bladder flushing helps to reduce the risk of crystal formation.
In some cases, surgical intervention may be necessary to remove bladder stones, especially if your dog is showing severe symptoms or has obstruction of the urinary tract.
Treatment Options for Dogs
Dietary management is a crucial part of treating dogs with crystalluria. A special diet with low levels of protein, magnesium, and phosphorus can help prevent the formation of struvite crystals.
If your dog has formed bladder stones, surgical intervention may be necessary, especially if they're showing severe symptoms or have an obstruction in their urinary tract, or pyelonephritis.
In some cases, struvite stones can be dissolved with a combination of medication and diet. Regular check-ups with your veterinarian are essential to monitor your dog's progress.
Medical therapy may be started if your dog has urate crystals caused by liver dysfunction. Treating the underlying liver condition is crucial before starting medical therapy.
Surgery is needed to remove urinary stones made of calcium oxalate, as they cannot be dissolved.
Manipulating Your Dog's Diet

Feeding your dog a diet rich in grains and legumes can increase urine pH, making it a breeding ground for bacteria to multiply and cause UTIs and stone formation.
A diet poor in proteins and rich in grains promotes alkalinity, which is the perfect breeding ground for bacteria to multiply.
To prevent the formation of urine crystals, consider feeding your dog a low-carb, grain-free diet.
Diets that focus on meats and organs tend to decrease the urine pH.
However, advising dog parents to feed their dogs a diet solely composed of meat and organs might lead to the development of calcium oxalate stones.
Dogs that barely touch the water bowl and urinate less frequently experience a heightened risk of developing urine crystals.
For instance, a dog should ideally drink four cups of water for each cup of kibble to ensure sufficient bladder flushing.
These crystals may lead to cystitis—an inflammation caused by the crystals irritating the bladder's lining, eventually resulting in lower urinary tract disease.

Consequently, many dogs are in mild dehydration, increasing the likelihood of urine crystal formation.
If a prescription diet is necessary, it's advisable to choose a high-moisture canned food or even a raw diet.
Some breeds, such as Miniature Schnauzers, Yorkshire Terriers, Lhasa Apsos, and Miniature Poodles, are more susceptible to certain crystals.
Here's a list of breeds prone to specific types of crystals:
- Calcium oxalate: Miniature Schnauzers, Yorkshire Terriers, Lhasa Apsos, and Miniature Poodles
- Cysteine: Dachshunds, English Bulldogs, and Newfoundlands
- Ammonium urate or uric acid: Dalmatians, English Bulldogs, and Newfoundlands
- Struvite crystals: Miniature Schnauzers, Shih Tzus, Bichon Frises, Miniature Poodles, Cocker Spaniels, and Lhasa Apsos
Specific Crystals and Breeds
If you're a dog owner, especially a female dog owner, it's essential to know which breeds are more prone to crystals in their urine.
Certain breeds are indeed more susceptible to crystals, and it's crucial to be aware of these breeds to ensure your furry friend receives the proper care.
Dalmatians are known for being prone to urate crystals due to a unique genetic trait.
Miniature Schnauzers and Bichon Frisés often face issues with calcium oxalate crystals.
Yorkshire Terriers are also prone to developing calcium oxalate crystals.
Here's a quick rundown of the breeds we've discussed:
Diet and Water Intake

Diet plays a significant role in the formation of crystals in female dog urine. A diet poor in proteins and rich in grains promotes alkalinity, which can lead to the formation of struvite stones.
Many veterinarians believe that a low-carb, grain-free diet can help prevent struvite stones. Some breeds, such as Beagles, Cocker Spaniels, Lhasa Apsos, and Dachshunds, are more prone to developing struvite stones.
Dogs may not drink enough water to stay healthy, and a low-moisture diet can make them more susceptible to struvite stones. A dog should ideally drink four cups of water for each cup of kibble.
Increased hydration can help reduce the formation of crystals in female dog urine. The more water a dog drinks, the more diluted their urine becomes, leading to more frequent bladder flushing.
Dogs that barely touch the water bowl and urinate less frequently are at a higher risk of developing urine crystals. A diet consisting entirely of dry kibble can lead to mild dehydration and increase the likelihood of urine crystal formation.
pH Levels and Struvite
Normal pH levels for dog and cat urine is between 6 and 6.5, which puts it closer to the acidic end of the scale.

Urine pH levels play a crucial role in struvite crystal formation. A pH level between 6 and 6.5 is ideal, but commercial grain-laden pet foods can disrupt this balance.
Dogs that eat meat in the wild have a well-balanced acidic pH level, which is essential for preventing struvite crystal formation.
Struvite
Struvite crystals are a type of mineral deposit that can form in a dog's urine. They're more common in female dogs.
Struvite stones, also known as Kidney Stones, can be a serious health issue for elderly dogs and pets with health issues or poor immune systems. These pets may not be able to dissolve the struvite crystals on their own, which can lead to a more serious health condition.
Struvite stones are caused by several issues, including an imbalance in a dog's urine pH levels. This can occur alone or concurrently with other health issues.
Struvite stones are often seen in Shih Tzus, who are known for their luxurious coats and charming personalities.
pH Levels

Normal urine pH levels for dogs and cats are between 6 and 6.5, which puts them closer to the acidic end of the scale.
A pH level of 7 is neutral, but urine pH levels below 7 represent an acidic environment.
Dogs that eat meat in the wild have a well-balanced acidic pH level because meat is more acidic in nature.
Commercial pet foods, which often contain more grains and less meat, can lead to a more alkaline urine pH level.
A more alkaline urine pH level can create an environment where bacteria can thrive.
Struvite crystals that would normally pass can turn into uroliths, which are full of bacteria, in an alkaline urine environment.
Highly alkaline urine can kill beneficial bacteria and allow harmful bacteria to run rampant.
Calcium oxalate crystals develop in a dog's urine when the pH level drops below 6.5, indicating high acidity.
Certain Breeds and Crystals
Certain breeds are more prone to crystals in their urine, which can be a concern for dog owners. Dalmatians are particularly susceptible to urate crystals due to a unique genetic trait.

If you have a Dalmatian, it's essential to monitor their urine regularly for any signs of crystal formation. Miniature Schnauzers, on the other hand, often face issues with calcium oxalate crystals.
These crystals can cause a range of problems, from mild discomfort to life-threatening kidney stones. Bichon Frisés are also at risk of developing calcium oxalate crystals, which can be painful and require veterinary attention.
Yorkshire Terriers are another breed that's prone to calcium oxalate crystals, so it's crucial to keep an eye on their urine health.
Cracking Dog Behavior Codes
A balanced diet is key to preventing and managing urinary crystals in female dogs, just like it's essential for their overall well-being.
Regular check-ups with your veterinarian can help identify any underlying health issues that may be contributing to the formation of crystals in your dog's urine.
Plenty of water is crucial to help dissolve and flush out crystals, so make sure your furry friend always has access to fresh water.

Understanding the importance of prevention and management can help you catch any potential issues early on, ensuring your dog stays happy and healthy.
Remember, it's always better to be proactive when it comes to your dog's health, and regular check-ups can provide you with the peace of mind you need.
