Canine urethritis is a bacterial infection of the mucosa of the urethra, often secondary to urethral obstruction, urethral injury and spread by surrounding and adjacent tissue inflammation (e.g., cystitis, prepuce, vaginitis and endometritis). It is mostly seen in male dogs. It is clinically characterized by painful urination, hematuria, frequent urination, and purulent discharge. Etiology 1. caused by secondary infection after damage caused by mechanical and chemical pathogenic factors stimulating the mucosa of the urethra. 2. can be caused by the spread of inflammation from neighboring organs (prepuce, cystitis, endometritis, etc.). The sick dog urinates frequently, is painful and restless when urinating, and urine is discharged in an intermittent manner. In severe cases, the urine is cloudy and mixed with mucus, blood or pus; sometimes necrotic, detached mucosa is discharged. Another special symptom seen is that the male dog’s penis can be permanently erect; the female dog’s labia open from time to time. The sick dog resists examination of the pubic or external genital area, scratching at the slightest contact and avoiding examination. The first step is to control the infection and provide antibacterial and anti-inflammatory treatment with ampicillin 10mg/kg intramuscularly, ceftriaxone 20mg/kg intramuscularly and roxithromycin 5mg/kg orally. 2. Flush the bladder with 0.1% potassium permanganate solution. 3. Also take ammonium chloride internally to acidify the urine for better results. The UTI is a very important part of the dog’s health. 2.
