What are the common possible causes of sexual development disorders in dogs and cats?

Possible causes include congenital reproductive abnormalities, hormonal imbalances, infections, or tumours. Diagnosis requires a combination of blood tests, urinalysis, and imaging by a vet — consult your veterinarian for a thorough evaluation.

What tests does the vet typically run to find the cause?

Common tests include a physical examination, urinalysis, blood biochemistry, and abdominal ultrasound or X-ray. Advanced imaging or endocrine-specific tests may be arranged if needed to identify the cause.

What should I do if my pet has blood in the urine or cannot urinate?

Blood in the urine or inability to urinate are emergencies — seek veterinary care immediately. For milder symptoms such as increased urination or thirst, arrange a vet appointment as soon as possible to identify the cause.

What home care or preventive measures can I take?

Regular health check-ups, monitoring changes in water intake and urination, and maintaining access to fresh water and a safe environment are all helpful. Seeking veterinary care early when you notice anything unusual can reduce the risk of complications.

How much do the tests and treatment usually cost?

Costs vary by clinic and region — ask your vet for an estimate before proceeding.

When to See a Vet

Seek Emergency Care Immediately

•Complete inability to urinate or persistent straining to urinate
•Heavy bright-red blood or visible blood clots in the urine
•Lethargy combined with inability to stand or severe weakness

Schedule a Clinic Visit Soon (within 24–72 hours)

•Noticeably increased urination frequency or nighttime urination
•Significantly increased water intake with frequent visits to the water bowl
•Changes in appetite or noticeably decreased activity level lasting several days

01What symptoms indicate something is wrong?

Sexual development disorders in dogs and cats often present as urinary and behavioural changes. Typical signs include frequent urination, increased water intake, changes in appetite or energy levels, and occasionally abnormal urination or blood in the urine.

Noticeably increased urination frequency or nighttime urination
Increased water intake, frequently lingering around the water bowl
Changes in appetite (decreased or increased)
Lethargy or noticeably reduced activity levels
Abnormal urination (e.g. blood in urine or urinary incontinence)

Seek emergency care immediately if you notice the following symptoms:

⚠️ Unable to urinate or repeatedly straining with no output
⚠️ Large amount of bright red blood or visible clots in the urine
⚠️ Extreme lethargy or inability to stand
⚠️ Obvious signs of dehydration (sunken eyes)

02How to assess the situation at home? Key observations and when to seek emergency care

Observing and recording symptom changes at home helps your vet identify the problem quickly and streamlines the diagnostic process.

Record daily urination frequency and approximate volume each time (estimates or photos are helpful)
Measure and record your pet's daily water intake for at least three days
Note when changes in energy levels or behaviour occur
Watch for blood, clots, or urinary incontinence during urination
If symptoms persist or worsen, arrange a vet visit as soon as possible

03How does the vet make a diagnosis? Common tests and examinations

At the clinic, the vet will begin with a physical examination, followed by urinalysis, blood tests, and imaging to assess urinary and endocrine function.

Physical examination

abdominal and urogenital palpation to assess pain or masses

Urinalysis

urinalysis panel, urine specific gravity, and urine culture (if indicated)

Blood and biochemistry tests

assessing kidney function, electrolytes, and endocrine markers

Imaging

abdominal ultrasound or X-ray to evaluate the urinary tract and reproductive organs

Advanced tests

CT scan, specialist endocrine evaluation, or specialist referral if needed

04Treatment and aftercare: medications, dietary adjustments, and a care guide

Treatment depends on the underlying cause and may include medication, dietary changes, and regular monitoring — follow your vet's instructions for check-ups and tests.

Symptomatic or targeted medication based on the underlying cause
Dietary adjustment or prescription food to support urinary or metabolic health
Home care: ensure adequate fresh water, a stable environment, and appropriate rest
Regular follow-up visits as directed for urinalysis, blood tests, or imaging
For complex or poorly controlled cases, referral to an endocrinology or urology specialist is recommended

05What to prepare before the vet visit? Key steps to help your vet quickly identify the cause

Record when symptoms began, how often they occur, and how they have changed over time

Log daily water intake and urination frequency for three consecutive days and bring the notes to the appointment

List all current medications, supplements, and feeding habits

Record a short video of any abnormal urination or behaviour for the vet to review

Bring any previous test results or imaging records, or provide copies
