Symptoms to watch for
Early signs include vomiting, often within a few hours, followed by lethargy, loss of appetite, diarrhoea and belly pain. As the kidneys are affected, a dog may drink and urinate more, then less, and become very unwell. Kidney damage can take a day or two to show fully, which is why early treatment matters so much.

What happens
Grapes, and their dried forms, are toxic to dogs and can cause acute kidney failure. What makes them so worrying is how unpredictable they are - some dogs eat several with no obvious harm, while others become seriously ill from just a few. Because there is no way to know which dog will react badly, every grape has to be treated as dangerous.
