Urinary Tract Infections. The most common cause of frequent urination in canines is UTI or the urinary tract infection. UTI, also known as cystitis can be caused by the accumulation of bacteria. The condition affects more often female dogs, which have a shorter and wider urethra that allows bacteria to travel more easily to the bladder.
Frequent urination may be caused by diseases affecting the urinary tract at any level. The urinary tract includes the kidneys, the tubes connecting the kidneys to the bladder (ureters), the bladder, and the duct through which urine flows from the bladder out of the body (urethra). Several factors may be linked to frequent urination, such as: 1  Infection, disease, injury or irritation of the bladder. 2  Conditions that increase urine production. 3  Changes in muscles, nerves or other tissues affecting bladder function. 4  Certain cancer treatments. 5  Drugs or beverages that increase urine production.
