When to See a Vet

Seek Emergency Care Immediately

  • Complete inability to urinate with prolonged straining for several hours
  • Frequent appearance of large amounts of bright blood or blood clots in the urine

Schedule a Vet Visit Soon (Within 24–72 Hours)

  • Frequent urination attempts with noticeably small output each time
  • Bloody or significantly discolored urine
  • Frequent licking of the genital area or obvious signs of discomfort

01What Symptoms Indicate a Problem?

Urate urolithiasis in dogs and cats commonly causes visible blood in the urine, painful urination, or frequent attempts to urinate; be extra alert if lethargy or dehydration are also present.

  • Blood in the urine, dark-coloured urine, or visible blood clots
  • Straining to urinate, obvious discomfort, or crying out in pain
  • Frequent attempts to urinate but passing only small amounts each time
  • Urinating in unusual places or episodes of urinary incontinence
  • Repeatedly licking the genital area or adopting a persistently uncomfortable posture
  • Reduced appetite and decreased activity alongside abnormal urination

Seek emergency care immediately if you notice the following symptoms:

  • ⚠️ Complete inability to urinate with persistent straining for several hours
  • ⚠️ Heavy fresh blood or frequent blood clots in the urine
  • ⚠️ Severe lethargy accompanied by persistent vomiting or signs of dehydration

02How to Monitor at Home: Observation Tips and Emergency Warning Signs

Keeping detailed records at home helps your vet quickly assess the situation and determine the right timing for tests and treatment.

  • Note the date and time when symptoms were first noticed
  • Observe and record daily water intake and how often your pet drinks
  • Track daily urination frequency, volume, urine colour, and presence of blood
  • Use your phone to record short videos of urination or abnormal behaviour for reference
  • Weigh your pet daily and note any changes in appetite or energy level
  • Bring all observation notes and videos to the vet appointment for the doctor's reference

03How Will the Vet Diagnose This? Common Diagnostic Tests

Upon arrival at the clinic, standard tests are carried out to confirm the presence of stones, infection, or impaired kidney function, and to guide further management.

Physical examination

palpating the bladder to assess for tenderness or distension

Urinalysis and urine culture

to confirm haematuria, crystals, or bacterial infection

Blood and biochemistry panel

to evaluate kidney function and electrolyte status

Ultrasound

to identify stone location and size, and assess kidney changes

Advanced imaging (CT scan)

used for complex cases or when stone location is unclear

Crystal analysis or stone composition analysis to determine the underlying cause

04Post-Diagnosis Treatment and Care: Medications, Diet, and Home Management

Treatment is tailored to the severity of each case, ranging from supportive care to intervention or surgery, and follow-up visits are needed to track imaging and urinalysis results.

  • IV fluids and electrolyte support to correct dehydration and stabilise the patient
  • Medication or prescription diet adjustments to reduce the risk of stone recurrence
  • Catheterisation or surgical stone removal when necessary, at the vet's discretion
  • Regular follow-up visits after treatment or surgery for imaging and urinalysis monitoring
  • Key home care includes encouraging water intake and following the prescribed diet
  • Referral to a specialist hospital with urological expertise is recommended when needed
