If your dog has consumed grapes and is showing severe symptoms — such as vomiting, tremors, seizures, or collapse — they may need in-person emergency veterinary care immediately. If this is the case, we recommend calling our partner Pet Poison Helpline ($85 consultation fee). They work directly with your emergency vet to guide treatment and help resolve your pet's case faster.
When to call a vet
Go to the ER now
- ● Your dog ate any amount of grapes, raisins, currants, or food containing them.
- ● Your dog is vomiting repeatedly, seems very weak, is trembling, having seizures, collapsing, or cannot stand.
- ● Your dog is drinking or urinating much more than usual, or has stopped producing urine after a known or suspected exposure.
- ● The exposure was recent and you are not sure how much was eaten.
See a vet within 24 hours
- ● Your dog may have licked grape juice, eaten a small number of grapes, or gotten into mixed foods like raisin bread, trail mix, cereal, or baked goods.
- ● You are unsure whether the product contained grapes or raisins.
- ● Your dog has mild symptoms such as one episode of vomiting, diarrhea, drooling, or decreased appetite after a possible exposure.
Watch at home, call if it worsens
- ● Do not monitor at home without veterinary guidance after a grape exposure.
- ● Even if your dog seems normal, call your vet or Pet Poison Helpline right away because serious kidney injury can develop later.
What Happened & Why It's Dangerous
Grapes can be toxic to dogs
Grapes, raisins, and currants are linked to poisoning in dogs and can cause acute kidney injury. The toxic principle is believed to be tartaric acid, but individual sensitivity varies.
There is no reliably safe amount
Some dogs become seriously ill after eating only a small amount, while others may eat more and show fewer signs. Because response is unpredictable, every exposure should be treated as urgent.
Symptoms may start within hours
Vomiting and diarrhea often begin within 6 to 12 hours, but kidney injury may take 1 to 3 days to become apparent.
Kidney damage can be severe
Without fast treatment, poisoning can progress to dehydration, weakness, excessive thirst, reduced urine production, and life-threatening kidney failure.
What to Do Right Now
Stay calm and act quickly. Remove any remaining grapes or grape-containing food, keep the package or a sample if available, and call your veterinarian, an emergency clinic, or Pet Poison Helpline immediately. Do not give home remedies and do not induce vomiting unless a veterinary professional specifically tells you to do so. If your dog is weak, trembling, having seizures, or collapsing, go to the nearest emergency animal hospital right away.
