Some of the everyday foods you eat with no issues are toxic to your dog. Death can result in as few as three to four days; dogs who survive may suffer from long-term kidney disease.
Symptoms and Prognosis
Because no definitive quantity of grapes or raisins is known to make a dog sick, any case of ingestion should be considered potentially dangerous. The initial signs of toxicity, the ASPCA reports, include vomiting, diarrhea and lethargy; report them immediately to your veterinarian. Early medical intervention provides the best chance for avoiding or surviving acute renal failure, which can occur in dogs within 24 hours or a few days after eating grapes or raisins. The prognosis for a dog who survives can include long-term renal failure or kidney disease, which may require ongoing treatments, careful monitoring of hydration and diet, and frequent veterinary checkups.
