Dog urinary tract has purulent secretions

Dog urinary tract secretions with pus are often caused by inflammation of the urinary system, such as cystitis, urethritis, and other diseases. You can encourage your dog to drink more water, apply broad-spectrum antibiotics systemically, perform urethral disinfection with 40% urotropine injections, and administer oral drugs to acidify the urine. You can also combine the use of 0.1% Rifampicin solution or Chlorhexidine solution to irrigate the urethra or bladder.

Causes of Cystitis

Cystitis refers to the inflammation of the bladder mucosa and submucosa, with common pathogenic bacteria including staphylococcus and Escherichia coli. Infection can occur when bacteria enter the bladder through the bloodstream or urethra. Fungal growth, reproduction, and invasion can also cause infections. Some cases are caused by inflammation spreading from kidneyitis, ureteritis, and other inflammations. Another cause is bladder stones or neoplasms stimulating the bladder mucosa.

Symptoms of Cystitis

Dogs with cystitis usually exhibit symptoms such as urgency, dysuria, polyuria, oliguria, and constant urination posture. The dog's urine may have a distinct ammonia-like smell, become dark and sticky, and have white flocculent matter suspended in it. Laboratory testing will show alkaline or neutral urine with increased protein content.

Treatment for Cystitis

When a dog has cystitis, treatment usually involves using antibiotics, such as those containing amoxicillin or enrofloxacin. As enrofloxacin mainly targets the urinary tract, it is recommended to use it first. However, it is not suitable for young dogs due to potential side effects that may cause abnormal cartilage development.
