Cranberries have a long history in folk remedies for urinary tract health in both humans and pets, with the mechanism being proanthocyanidins (PACs) that prevent bacteria from adhering to bladder walls. While the clinical evidence in dogs is less robust than in humans, some veterinary formularies include cranberry extract for recurrent UTI support.

Fresh or frozen plain cranberries are very tart — most dogs dislike them. A few berries mixed into food are safe. The sourness and bitterness mean few dogs will voluntarily overeat them.

Dried cranberries (Craisins) are problematic: they're sweetened with large amounts of sugar, and some versions contain raisins mixed in. Cranberry sauce is high in sugar. Cranberry juice cocktail is acidic and high in sugar. Cranberry supplements designed for dogs are the safest way to deliver any potential urinary benefit.

Quelle quantité est dangereuse ?

Fresh berries: not toxic. Dried/sweetened versions: high sugar and potential raisin cross-contamination.

Quels sont les symptômes ?

DÉBUT :N/A for fresh berries in small amounts.
  • tart berry excess: GI upset; dried sweetened versions: sugar GI effects

Que dois-je faire ?

Fresh or frozen cranberries: no action needed. Dried cranberries from mixed fruit: check for raisins, call vet if present.
