Fruit
Grapes
Not Safe
Grapes are not safe for dogs. Eating grapes can cause gastrointestinal illness and, in some dogs, serious kidney injury or kidney failure.
- Potentially Toxic
Suspected grape ingestion?
Contact a veterinarian or pet poison service promptly.
Safe part
None.
Avoid
Do not intentionally give grapes to dogs.
Preparation
No preparation makes grapes reliably safe for dogs.
Serving guidance
No intentional serving is appropriate.
Nutritional note
Any potential nutritional benefits of grapes do not outweigh the potential toxicity risk for dogs.
Did your dog already eat some?
If your dog has eaten grapes, contact your veterinarian or a pet poison service promptly rather than waiting for symptoms. If possible, note approximately how many grapes were eaten, when they were eaten, and your dog's approximate weight.
Veterinary guidance
Prompt veterinary or pet-poison guidance is appropriate after suspected grape ingestion because serious kidney injury can occur and the response to ingestion can vary between dogs.
Why we say this
Grape ingestion has been associated with acute kidney injury in dogs. The exact toxic mechanism has not always been clear, but tartaric acid is a suspected toxic component. The amount that causes illness can vary, so a simple ‘safe number of grapes’ rule should not be used.
