Grapes might seem harmless but for dogs, they’re one of the most dangerous fruits you can offer. Even a small handful can cause sudden kidney failure. Here’s what every dog owner needs to know about why grapes are toxic and what to do if your pup eats one.
⚠️ Are Grapes Safe for Dogs?
No — grapes and raisins are highly toxic to dogs. Even one or two can trigger acute kidney failure in some dogs.
What makes them dangerous is still unclear — scientists suspect natural compounds in the grape’s skin or flesh cause a severe reaction in canine kidneys.
🚫 Never feed grapes, raisins, currants, or sultanas — in any form.That includes fresh grapes, dried fruit, mixed snacks, cakes, and cereals.
🧠 Why Grapes Are Dangerous
Grape Form | Toxic Level | Example Foods to Avoid |
Fresh grapes (any colour) | 🔴 Very high | Whole fruit, fruit salads |
Raisins / sultanas | 🔴🔴 Extremely high | Trail mix, flapjacks, cereal |
Baked goods | 🔴 High | Hot cross buns, fruit cake |
Grape juice or extract | 🔴 Medium | Flavoured drinks, jelly sweets |
⚠️ Even organic, seedless, or peeled grapes can be deadly — no type is safe.
🩺 Symptoms of Grape or Raisin Poisoning
Signs usually appear within 6–12 hours of eating grapes and can worsen rapidly:
Vomiting or diarrhea
Loss of appetite
Lethargy or weakness
Excessive thirst or urination (then none at all)
Tremors or abdominal pain
If untreated, this can lead to renal (kidney) failure and be fatal.
☎️ Call your vet or an emergency animal clinic immediately.Do not wait for symptoms — even one grape can cause harm.
🧮 How Much Is Dangerous?
There’s no safe amount of grapes or raisins for dogs. Even a single grape has caused severe illness in small breeds.
Dog Weight | Risk Level | Example |
2–5 kg | 🔴 Critical | 1–2 grapes |
10–15 kg | 🔴 Severe | 3–5 grapes |
20+ kg | 🔴 High | 6–10 grapes or a handful of raisins |
All breeds, ages, and genders are susceptible — sensitivity varies by dog.
🧩 What To Do If Your Dog Eats Grapes
Stay calm and call your vet immediately.
Tell them your dog’s weight, how many grapes, and when it happened.
Follow their instructions — they may induce vomiting or use activated charcoal.
Do not wait to “see what happens” — early treatment saves lives.
🏥 If caught early, most dogs recover fully with prompt veterinary care.
