Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
Fresh or dried cranberries (unsweetened) are safe for dogs in moderation and contain antioxidants and vitamins C and E. However, their tart flavour means most dogs do not enjoy them plain. Sweetened dried cranberries, cranberry sauce, and cranberry juice contain too much sugar and should be avoided. Some dogs may experience stomach upset from the acidity. Cranberry supplements marketed for urinary health should only be used under veterinary guidance.
What You Should Know
While cranberries is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
