Dog Ate Grapes: What to Do, Symptoms, and When to Seek Care

If your dog ate grapes, it’s important to act immediately. Grapes are highly toxic to dogs, and even small amounts can lead to serious kidney damage.

Because there is no known “safe” amount, any ingestion should be treated as an emergency.

What to Do If Your Dog Ate Grapes

If your dog has eaten grapes, take these steps right away:

• Remove any remaining grapes so your dog cannot eat more
• Estimate how many grapes were consumed
• Note your dog’s weight and the time of ingestion
• Call a veterinarian immediately for guidance

You can also contact ASPCA Animal Poison Control: 888-426-4435

Same-day urgent care appointments are available.

Are Grapes Toxic to Dogs?

Yes, grapes and raisins are toxic to dogs and can cause acute kidney failure. The exact reason why they are toxic is not fully understood, and reactions can vary widely between dogs.

Some dogs may develop severe illness after eating only a small amount, while others may not show symptoms right away—but the risk is always present.

Symptoms of Grape Toxicity in Dogs

Symptoms may begin within a few hours but can also be delayed. Common signs include:

• Vomiting
• Diarrhea
• Loss of appetite
• Lethargy
• Abdominal pain
• Increased thirst or urination early on
• Decreased or no urination as kidney damage progresses

Kidney failure can develop within 24–72 hours if not treated.

When Should You Call a Veterinarian?

You should contact a veterinarian immediately if:

• Your dog ate any amount of grapes or raisins
• You are unsure how much was consumed
• Your dog is showing any symptoms
• Your dog is small, a puppy, senior, or has underlying health conditions

Do not wait for symptoms to appear—early treatment is critical.
