Can dogs eat grapes?

No, grapes can be highly toxic to dogs, so you should never feed this fruit to your pet and make sure that they don’t have easy access to it either. Ingesting grapes or raisins can be fatal for dogs. This is true no matter your dog’s breed, size or the amount ingested. And because scientists haven’t yet identified the exact substance in grapes that is toxic to dogs, your pet should avoid any type of grape-related product.


What are the signs of grape poisoning in dogs?

The answer to the question ‘can dogs have grapes’ is a resounding no. But if you’re worried that your pet has helped themself, you should contact your vet straight away, even if your pet is not yet showing any symptoms. Signs of grape or raisin toxicity include:

  • Vomiting
  • Diarrhoea
  • Lethargy
  • Panting and dry nose as symptoms of dehydration
  • Difficulty breathing
  • Excessive thirst

Do not delay in contacting your vet, as your dog could develop serious health problems such a kidney failure.


Why can some dogs have grapes without showing any toxicity symptoms?

Whether your dog has eaten grapes in the past and seemed unaffected, or you’ve heard stories about owners feeding one or two grapes to their dog as a treat, there are many reasons why you shouldn’t assume your dog is immune to grape poisoning.

Firstly, scientists haven’t yet managed to completely understand why grapes are such a toxic food to dogs. Dosage is one of the main mysteries, as some dogs become unwell after a single grape whereas others have been known to eat several without issues. While the dose considered toxic can vary from dog to dog, it’s not a good idea to try and find out what that is for your dog.

Even if your pet does not show obvious signs of poisoning at first, you shouldn’t assume the pet is immune. There can sometimes be a delay in symptoms developing, and by this point your pet could already have very severe health complications. This is why, if you’ve witnessed your dog eating grapes, it’s important to call your vet immediately and not wait for symptoms to show up. The quicker the intervention, the better the chances that your dog won’t suffer fatal consequences.
