What the research says
A 2026 systematic review found three small studies of cranberry for urinary infections in dogs and cats, and its authors said they could not tell whether cranberry works. Weese notes that no commercial product has published supporting data and that these products are probably harmless.7 SkeptVet covers two dog studies: a 2016 study of 12 dogs did not establish a benefit, and a 2017 trial found no effect.8 For dose, the 11 products here give 150 mg to 600 mg of cranberry a day to a 50 lb dog. A dog that strains to urinate or has blood in the urine needs a vet.
