Can dogs eat sultanas?
The full picture
Sultanas, along with raisins and currants, are dried grapes and share the tartaric acid toxicity that can cause acute kidney failure in dogs. Because they are dried and concentrated, sultanas are gram-for-gram more toxic than fresh grapes. Toxicity is unpredictable — some dogs react to tiny amounts, others eat more and appear fine — so every ingestion should be treated as an emergency. Sultanas are common in UK baking: hot cross buns, mince pies, fruit cake, Christmas pudding, scones, teacakes, spotted dick, bread pudding, and Eccles cakes.
