How long to observe if a dog eats grapes?

Dog poisoning after eating grapes usually occurs within 6 hours. Generally, 6 hours of observation is enough. Dogs generally have no problem eating one or two grapes. There are reports in the literature that dogs may be poisoned if they eat more than 11.5g of grapes per kilogram of body weight. If your dog eats a large number of grapes, it is recommended to induce vomiting with soapy water or hydrogen peroxide, and then send it to the hospital for treatment.
