One dangerous health consequence of eating raisins and sultanas is kidney failure. Dogs that suffer from kidney failures will show a number of concerning symptoms such as vomiting, loss of balance, and a significant loss in appetite. We would call the emergency vet immediately as soon as you suspect that your dog has eaten some raisins or sultanas.

How soon after eating raisins will a dog get sick?

Symptoms can start to show a few hours after a dog ate some raisins. You should never assume your dog is okay as animals, in general, are known for “hiding” their sickness when they become vulnerable. For reference, the lowest toxic dose of raisins in confirmed cases has been about 3 grams per kg. An average raisin weighs around 0.5 grams so we could assume a toxic dog of 6 raisins per kg.
