What happens when a dog eats grapes? Poisoning can occur when a dog eats grapes, which can occur within six hours after eating grapes. The symptoms are depression, vomiting, diarrhea, and grape residue in the dog’s vomit and excrement. Just like acute gastroenteritis in humans, there are many similarities. However, the physiology of dogs is different from that of humans. When eating unadapted food, people will eliminate it from all sides, while dogs can only eliminate toxins out of their bodies through their kidneys. Dogs eating grapes will also have a severe case, which is usually found after 24 hours. It is acute renal failure, in the early stages the dog does not urinate and drinks frantically.
