Among the common urinary issues for dogs, urethritis is most frequently caused by bacterial infection. Bacteria enter through the urethra, travel to the bladder, and cause inflammation. Female dogs are at higher risk due to their naturally shorter urethra. Additional risk factors include inadequate water intake, prolonged urine retention, bladder stones, prostate disease, urinary tract tumours, and long‑term diets high in minerals. Older dogs and those with chronic conditions such as diabetes are also more vulnerable due to weakened immune systems, making proper dog urinary tract health management especially important.
