How to Treat Yellow Pus Draining from Dog's Urethral Opening

If your male dog has a yellow pus draining from its urethral opening, it may be infected. You can buy some metronidazole and chlorhexidine to wash it and ensure proper disinfection. Also, accompany it with an Elizabethan collar to prevent licking. If it's a female dog, it might be pyometra. If the yellow pus-like substance flows, it's recommended to take it to the hospital for an ultrasound to check if the uterus is thickened. If it is, timely surgery for spaying is advised.

Pyometra Precursors

Initially, there may be fever, depression, loss of appetite, decreased activity, lethargy, and sometimes vomiting. As the disease progresses, there will be loss of appetite, excessive drinking and urination, weight loss, increased abdominal circumference, and physical exhaustion. In the later stages, the dog's vulva will discharge unclean fluids. The abdomen becomes larger, respiratory and heart rates increase, and sometimes panting occurs. The abdominal skin becomes tense, subcutaneous veins protrude, and the dog tends to lie down more.

Conservative Treatment for Pyometra

If diagnosed with pyometra, it is recommended to undergo a uterine-ovarian removal surgery as soon as possible. Since a dog's uterus is shaped like a double horn, irrigation cannot thoroughly clean the uterine corners. Even with antibiotic conservative treatment, it remains unable to completely kill the purulent bacteria hiding in the uterine corners. Once the dog's resistance decreases, bacteria in the uterus will multiply rapidly. Therefore, conservative treatment is only a temporary solution and not a fundamental one.

How to Disinfect Urethral Opening Yellow Pus

Yellow pus at the urethral opening is usually caused by urinary system inflammation, such as cystitis and urethritis. You can encourage your dog to drink more water, apply broad-spectrum antibiotics systemically, inject 40% urotropine for easy urethral disinfection, and administer oral drugs to acidify the urine. Combine the use of 0.1% rifampin solution or chlorhexidine solution to irrigate the urethra or bladder.
