Understanding the causes, treatment options and symptoms for kidney stones is essential for any pet owner. This blog offers a comprehensive guide to kidney stones in dogs, helping you recognize the signs and know when to seek veterinary assistance.
What Are Kidney Stones?
Kidney stones are hard, mineral-based formations that develop in the kidneys. They can differant in shape and size, and their presence can lead to several health issues. These stones form when certain minerals in the urine become highly concentrated and crystallize. Dogs' most common types of kidney stones include calcium oxalate, struvite, urate, and cystine stones.
Causes Of Kidney Stones In Dogs
Some factors can contribute to the formation of kidney stones in dogs, including:
- Genetics: Genetic factors predispose Certain breeds to develop kidney stones. Miniature Schnauzers, Lhasa Apsos, Yorkshire Terriers, and Dalmatians are particularly susceptible.
- Diet: Diets high in certain minerals, such as oxalate and calcium, can increase the risk of stone formation. Additionally, diets lacking adequate water intake can lead to concentrated urine, which promotes stone formation.
- Urinary Tract Infections (UTIs): Recurrent UTIs can alter the pH balance of the urine and create an environment conducive to stone formation.
- Metabolic Disorders: Conditions like hypercalcemia (elevated calcium levels in the blood) and other metabolic disorders can increase the likelihood of kidney stone development.
- Medications: Some medications may contribute to the formation of kidney stones as a side effect.
Symptoms Of Kidney Stones In Dogs
Recognizing the symptoms of kidney stones in dogs is vital for early detection and treatment. Common signs include:
- Frequent Urination: Dogs with kidney stones may attempt to urinate more frequently but pass only small amounts of urine.
- Blood in Urine: Blood in the urine or hematuria, is a common symptom of kidney stones. The urine may appear pink, red, or brown.
- Straining to Urinate: Dogs may experience pain and discomfort while urinating, leading to straining.
- Abdominal Pain: Kidney stones can cause significant abdominal pain, leading to a hunched posture or reluctance to move.

Diagnosis Of Kidney Stones In Dogs
If you persume that your dog has kidney stones, it is necessary to seek veterinary care immediately. A vet will go thorough physical examination and may recommend the following diagnostic tests:
- Urinalysis: This test helps identify abnormalities in the urine, such as the presence of crystals, blood, or signs of infection.
- Blood Tests: It can help identify underlying metabolic disorders and assess kidney function.
- Imaging: X-rays or ultrasounds are commonly used to visualize kidney stones and determine their size and location.
Treatment Options For Kidney Stones In Dogs
The treatment approach for kidney stones in dogs depends on the size, type, and location of the stones and the severity of the symptoms. Common treatment options include:
- Dietary Management: Special diets formulated to dissolve certain types of stones or prevent their formation can be beneficial. Increasing water intake is essential to dilute the urine and lower the risk of stone formation.
- Medications: Pain relievers, antibiotics (if a UTI is present), and medications to alter urine pH may be prescribed to manage symptoms and prevent recurrence.
- Surgical Removal: In cases where stones are large, causing severe symptoms, or cannot be dissolved with dietary management, surgical removal may be necessary. Procedures such as cystotomy or nephrolithotomy can be performed to remove the stones.
- Extracorporeal Shock Wave Lithotripsy (ESWL):This non-invasive procedure uses shock waves to break the stones into smaller fragments that can be passed through the urine.
- Ureteral Stents or Subcutaneous Ureteral Bypass (SUB): These procedures may be necessary if stones cause a blockage in the urinary tract, ensuring urine can bypass the obstruction.
