Short answer

Cranberries are safe for dogs, so any mild digestive upset should pass quickly. Just watch your dog for the next 24 hours to ensure the diarrhea resolves and no new symptoms like vomiting or lethargy appear. Offer small amounts of plain water and a bland diet if needed. Contact your own vet if the diarrhea continues beyond a day or if your dog seems unwell.

Cranberries — Food safety facts

Safe to share · Dogs · full breakdown on the linked food page

Fresh or dried (no added sugar) cranberries are safe in small amounts.

Dogs and cats carry the same rating (Safe to share), so the notes below hold for either pet.

Cranberries is not toxic to dogs. The real limit is calories, fat and salt, so treat it as a small extra alongside the normal ration rather than a meal in itself.

There is no poisoning risk here, and the usual problem is simply eating too much at once: a heavy fat or salt load can bring on loose stools or a single vomit. Offer water, keep an eye on the pet for 24 hours, and do not induce vomiting.

Why these cautions matter

Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
