What causes e coli in dogs urine?

E. coli in a dog's urine is typically caused by a urinary tract infection (UTI), which can occur when bacteria from the gastrointestinal tract enter the urinary system. Factors that contribute to this include poor hygiene, urinary retention, anatomical abnormalities, or underlying health issues that compromise the immune system. In some cases, E. coli may also be introduced through contaminated water or food. Urinary infections can lead to symptoms such as frequent urination, straining to urinate, and discomfort.
