Can dogs eat cranberries?

Yes — plain, in small amounts

Yes. Fresh or frozen plain cranberries are safe for dogs in small amounts. Cranberry sauce and dried cranberries are not — too much sugar.

The full picture

Fresh or frozen plain cranberries are perfectly safe for dogs and contain beneficial antioxidants and vitamin C. They're very tart though, and most dogs don't love them. They're sometimes recommended for urinary health but the evidence for dogs is limited — ask your vet before using for that purpose. The big cautions: cranberry sauce (loaded with sugar, sometimes alcohol or orange zest), dried cranberries (often sold in trail mixes with raisins — which are toxic), and cranberry juice (usually sweetened).

Safe portion size

A few berries for small dogs, a small handful for large dogs.

And while you're thinking about what's good for your dog, keeping on top of flea and parasite prevention is just as important as diet.
