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).

Does size or breed matter?
No specific toxicity concern from ripe cranberries flesh itself. As with most fruit, small and toy breeds should get proportionally smaller portions given their lower daily calorie/sugar allowance, and any dog prone to weight gain, diabetes, or pancreatitis should have cranberries as an occasional treat rather than a regular one. Check for and remove any pit, stone, or large seed before serving, as these are a choking and obstruction risk regardless of breed.
