Quick Answer
Cranberry Urinary Tract Infection Meta-Analysis has evidence relevant to safety, limits, and clinician-discussion contexts, but conclusions should stay close to the cited sources. One representative finding is: The small number of studies, small sample sizes, data from those studies, and low certainty of evidence preclude confident assessment of the role of cranberry for the prevention or treatment of infectious urinary tract disease in dogs and cats.
