About Cranberry

Cranberry is a fruit ingredient added to some pet foods and supplements for fiber, antioxidants, and urinary health marketing claims.

Cranberries are used in pet foods and supplements as a source of fiber and antioxidants (notably polyphenols/proanthocyanidins) and are commonly included for their potential urinary tract–supporting properties in dogs and cats. While these compounds may help inhibit bacterial adhesion in the urinary tract, scientific evidence in pets is limited, and owners should choose unsweetened, preservative-free preparations (avoiding products sweetened with xylitol), watch for gastrointestinal upset or effects on urine pH, and consult a veterinarian for pets with urinary stones or taking certain medications.

Why it's used

Cranberry is added because its proanthocyanidins are theorized to interfere with bacterial adhesion in the urinary tract, and the fruit also contributes fiber and antioxidant compounds to a formulated diet. Manufacturers frequently market it on this urinary angle even though the underlying mechanism in companion animals is not fully worked out.

Common concerns

  • Weak clinical evidence in pets A 2026 systematic review in the Journal of Veterinary Pharmacology and Therapeutics found only three small studies (122 animals total) on cranberry for urinary tract disease in dogs and cats, none showing a statistically significant benefit, and rated the overall certainty of evidence as low to very low.
  • Product formulation Cranberry preparations for pets vary widely, and products sweetened or flavored with additives such as xylitol are a separate hazard unrelated to the cranberry itself, so formulation matters when choosing a product.

Also relevant

Cranberry's proposed mechanism involves proanthocyanidins thought to reduce bacterial adhesion in the urinary tract, a pathway studied far more in humans than in dogs and cats.
