If a dog eats a grape, it can be very dangerous and potentially fatal. Grapes and raisins contain a toxin-most likely tartaric acid-that can cause acute kidney failure in dogs, even if only one grape is ingested
. The toxic effects vary among dogs, with some showing severe symptoms while others may appear unaffected, but there is no known safe amount for any dog to consume
Symptoms of Grape Toxicity in Dogs
- Vomiting and/or diarrhea, often within a few hours of ingestion
- Loss of appetite and lethargy
- Increased thirst and urination initially, which may progress to decreased or no urination as kidney failure develops
- Abdominal pain and dehydration
- Bad breath (ammonia-like)
Risks
- Acute kidney failure can develop within 24 to 48 hours after eating grapes
- Kidney damage can be severe and irreversible, potentially leading to death or euthanasia if untreated
- Grapes can also be a choking hazard, especially for small dogs
What to Do If Your Dog Eats Grapes
- Contact a veterinarian immediately for advice
- The vet may induce vomiting and administer activated charcoal to prevent toxin absorption
- Treatment often includes IV fluids to support kidney function and medications to manage symptoms
- Hospitalization for at least 48 hours is usually necessary for monitoring and treatment
Summary
Dogs should never eat grapes or raisins. Even a single grape can cause severe kidney damage or death. If ingestion occurs, prompt veterinary care is critical to improve the chances of recovery
. If you suspect your dog has eaten grapes, do not wait for symptoms-seek veterinary help immediately.
