What to Do If Your Dog Eats Grapes or Raisins

Are Grapes Dangerous for Dogs?

Yes — grapes and raisins are one of the most dangerous foods for dogs. They can cause acute kidney failure, and the toxic mechanism is still not fully understood. Critically: there is no established safe dose. Some dogs have eaten large amounts with no apparent effect; others have developed kidney failure after eating just a few grapes. Because of this unpredictability, any grape or raisin ingestion must be treated as a potential emergency.

Raisins Are More Dangerous Than Grapes

Raisins are concentrated grapes — the toxic compounds are more concentrated per gram. A small box of raisins can be lethal for a small dog. Watch for raisins in trail mix, cereal, baked goods, and granola bars.

What to Do Immediately

1. Call poison control or your vet right now:
   • ASPCA Animal Poison Control: (888) 426-4435
   • Pet Poison Helpline: (855) 764-7661
2. Note the details: How many grapes/raisins, when eaten, your dog's weight
3. Induce vomiting only if directed by poison control or your vet — most effective within 2 hours
4. Go to the emergency vet — do not wait for symptoms

Signs of Grape/Raisin Toxicity

Symptoms typically appear within 6–12 hours:

• Vomiting (often within hours of ingestion)
• Diarrhea
• Lethargy and weakness
• Loss of appetite
• Abdominal pain
• Decreased or absent urination (sign of kidney failure — emergency)
• Tremors

Treatment

Treatment involves inducing vomiting (if recent), activated charcoal, aggressive IV fluid therapy to protect the kidneys, and monitoring kidney values. Early treatment dramatically improves outcomes. Dogs that develop kidney failure have a much poorer prognosis.

💊 Recommended: Activated Charcoal for Dogs and Cats — Use only under veterinary or poison control guidance. Non-GMO powder, 3.53 oz.

Prevention

• Never give grapes or raisins as treats
• Keep grapes, raisins, and products containing them (trail mix, granola, fruit cake) out of reach
• Educate all family members and guests
• Check ingredient lists on baked goods before sharing with your dog
