Can Dogs Eat Grapes? – No, They Can’t

It’s a common question that pet parents might ponder: can dogs eat grapes? The direct and simple answer is No. Grapes, along with raisins, are harmful to dogs and can lead to serious health issues, including potentially fatal kidney failure. Even small amounts of this fruit can be toxic, so it’s important to keep grapes out of reach from our furry friends.

Can Puppies Eat Grapes?

When it comes to puppies, the answer remains a resolute No. Their smaller bodies and underdeveloped systems mean that puppies are even more susceptible to the toxins present in grapes. The ingestion of grapes can be significantly more dangerous for puppies, potentially leading to rapid onset of symptoms and severe reactions.

Why Are Grapes Harmful for Dogs?

While the exact substance in grapes that causes toxicity in dogs remains unidentified, the consequences are well-documented and recognized among veterinarians.

Acute Kidney Failure

The most severe risk associated with grape ingestion is acute kidney failure. This sudden loss of kidney function can develop within a matter of days, or even hours, after a dog eats grapes. The kidneys fail to filter waste from the blood, which can lead to a buildup of toxins in the body.

Digestive Disturbance

Grapes can cause vomiting and diarrhea in dogs, symptoms that typically appear within a few hours of ingestion. These are not only unpleasant for your pet but can also lead to dehydration and worsen the overall condition.


Eating grapes can lead to a drop in calcium levels in dogs, known as hypocalcemia. This electrolyte imbalance can cause further complications and exacerbate the toxicity’s effects.

Symptoms to Watch Out For After Dogs Consume Grapes

  • Lethargy: If you notice your dog is unusually tired or weak, it could be a sign that something is not right.
  • Vomiting or Diarrhea: These are often the first symptoms to appear and can occur within a few hours after eating grapes.
  • Abdominal Pain: A dog that has ingested grapes might show signs of abdominal discomfort, such as whining or a hunched posture.

Immediate Steps to Take if Your Dog Eats Grapes

  • Do Not Wait: If you believe your dog has eaten grapes, it is crucial to act immediately even before symptoms occur.
  • Contact Your Vet: Get in touch with your veterinarian or the nearest animal hospital as soon as possible for professional advice.
  • Prevent Access: Make sure to remove any remaining grapes or raisins to prevent further ingestion.

Safe Alternatives to Grapes

While grapes are dangerous for dogs, there are safe alternatives that they can enjoy. Consider offering your dog these safer food options instead:

  • Carrots – These are not only safe but also beneficial due to their high fiber content and vitamins.
  • Apples – Apples (without seeds) can be a tasty and healthy snack in moderation.
  • Blueberries – Full of antioxidants, blueberries are a great nutritious treat for dogs.


To summarize, grapes are a definitive no-go for our canine companions. The risks involved with grape consumption, like acute kidney failure and digestive problems, are too great to ignore. As responsible pet owners, our vigilance and knowledge are crucial in preventing our pets from accessing dangerous foods. Thankfully, there are plenty of safe and delicious alternatives that dogs can enjoy without any harm.
