What to Do When a Dog Has Urethral Discharge (Pus)
📝 Summary
Canine urethral abscess results from urethral inflammation in dogs and requires prompt medication. Bacterial infection of the dog's urethral mucosa is also called a urinary tract infection, medically known as urethritis. Main symptoms include painful urination, urethral swelling, sensitivity of the urethral opening, redness and swelling of the urethral orifice, and difficulty inserting a catheter, more commonly seen in dogs.
1 Overview
I. Cause Analysis of Urethral Discharge in Dogs
Irritation of the urethral mucosa by mechanical and chemical pathogenic factors leads to injury followed by secondary infection.
It may result from the spread of inflammation from adjacent organs (such as balanitis, cystitis, endometritis, etc.).
Clinical symptoms of urethritis in dogs.
The dog’s penis is swollen and sensitive, and the urethral opening appears red and swollen. During urethral exploration, the dog shows pain and the catheter is difficult to insert.
Painful urination and difficulty urinating; cloudy urine with pus and blood; urination in a thin stream; the dog is clearly in distress.
The affected dog shows painful dripping urination; due to inflammation, urination does not stop, the male dog’s penis flickers frequently during urination, and the female’s vulva remains open.
The urine is turbid and unclear, excreted with mucus and blood, and sometimes the urethral mucosa necroses and sloughs off.
II. Management of Urethral Discharge in Dogs
1. Control secondary infection and fight inflammation with antibiotics: ceftriaxone 20.0 mg/kg by intramuscular injection; ampicillin 10.0 mg/kg intramuscular injection; oral roxithromycin 5 mg/kg.
2. Rinse the bladder with 0.1% potassium permanganate solution; taking ammonium chloride internally to acidify the urine works even better.
When the dog’s condition is severe, targeted treatment is required.
