The reasons that cause pus-like things to drip from the dog's urine are as follows:

1. The dog's urethra may have been scratched by a sharp object, causing the wound to become infected and suppurative.

Treatment method: The owner needs to flush the wound with saline and clean up all the pus. If the wound is deep or the dog has redness, swelling, pain and other symptoms, it is recommended to seek medical treatment in time.

2. Urinary tract infection in dogs may also cause similar symptoms.

Treatment method: It is recommended that the owner use potassium permanganate solution to flush the urethra and give the dog antibiotics, such as cephalosporins, amoxicillin, etc., to control the infection.
