Is prostatitis contagious between dogs or cats?

Prostatitis is generally associated with individual urinary tract infections or other internal factors and is not commonly classified as a directly contagious disease. If you have concerns, ask your vet whether isolation or screening of other pets in the household is advisable.

What tests will the vet run at the appointment?

Common diagnostics include blood work (CBC and biochemistry), urinalysis, abdominal ultrasound, and radiographs. Prostatic cytology or bacterial culture may also be performed to guide antibiotic choice.

Does a prostatic abscess always require surgery?

Whether surgery is needed depends on the imaging findings and clinical status. Some cases respond well to drainage or medical management alone. Your vet will advise on the most appropriate approach after evaluation.

What should owners watch for at home during treatment?

Monitor and record body weight, appetite, water intake, and urination at home. Save video clips of urination or activity to share at rechecks, and follow your vet's schedule for follow-up appointments and repeat testing.

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 obvious urinary obstruction
•Persistent high fever or extreme lethargy
•Heavy bloody urine or continuous bleeding that does not stop

Schedule a clinic visit soon (within 24–72 hours)

•Frequent urination or noticeably increased urination
•Signs of pain or straining during urination
•Decreased activity level or noticeably reduced appetite

01What symptoms indicate a problem?

Prostatitis and prostatic abscess in dogs commonly present as changes in general condition alongside urinary abnormalities. Early observation helps determine whether veterinary care is needed.

Lethargy and noticeably reduced activity — note the time symptoms began
Decreased appetite or complete refusal to eat lasting more than one day
Abdominal or pelvic tenderness — your pet may flinch or resist being touched
Changes in urination: straining, increased frequency, or altered urination pattern
Tenesmus or blood in the urine (haematuria) — record how often this occurs

Seek emergency care immediately if you notice the following symptoms:

⚠️ Complete inability to urinate or obvious urinary obstruction
⚠️ Persistent high fever or extreme lethargy and unresponsiveness
⚠️ Heavy haematuria or continuous bleeding that does not stop

02How to assess the situation at home and know when to seek emergency care

Recording key observations at home helps your vet quickly understand the condition and monitor how well treatment is working.

Record when symptoms started and track daily changes
Weigh your pet daily and note any significant weight loss
Monitor urination frequency, urine colour, and whether urination appears painful or difficult
Film urination and activity with your phone to share with your vet
Track changes in appetite, water intake, and bowel movements

03How will the vet diagnose this? Common diagnostic tests

After a physical examination, your vet will use diagnostic tests to assess prostate size, architecture, and the extent of infection, and determine whether further intervention is needed.

Complete blood count and biochemistry panel

assesses systemic inflammation and organ function

Urinalysis and urine sediment

checks for signs of infection or haematuria

Abdominal radiographs

evaluates prostate size, calcification, or other abnormalities

Abdominal ultrasound

examines prostatic structure, enlargement, or the presence of abscess

Prostatic cytology or fine-needle aspirate

assesses cells and fluid where indicated

Bacterial culture and sensitivity testing

guides antibiotic selection

04Treatment and home care after diagnosis: medications, diet, and recovery guide

Treatment focuses on controlling infection and managing the abscess, with medications, possible drainage or surgery, and scheduled follow-up testing based on diagnostic findings.

Antibiotic therapy is the primary treatment; the specific drug may be adjusted based on culture results
If an abscess is present, drainage or surgical evaluation may be required
Regular blood and urine monitoring is needed during treatment to track infection and organ function
Schedule rechecks and follow-up ultrasound imaging as directed by your vet
Diet management and weight monitoring support recovery — keep a daily log
If symptoms do not improve or recur, referral or specialist evaluation is recommended

05What to prepare before the vet visit: key information to help your vet work efficiently

Write down when symptoms started, how often they occur, and any daily changes

List all current medications, supplements, and relevant medical history

Bring video footage of urination or activity for your vet to review

Note recent toileting patterns and daily water intake

Bring any previous diagnostic reports such as radiographs or ultrasound images

Call ahead to confirm the clinic can perform ultrasound or bacterial culture during your visit
