We all love grapes. And tiny grapes are hard to eat without dropping. But when you have a pet at your home and as soon as you drop a grape, your dog just snatches that grape and eats it. Now if you do not know whether can dogs eat grapes? the answer is No, You cannot feed your dog grapes.

There is no exception in which dogs can have grapes. Grapes are highly toxic for some dogs. Never ever try to feed your dog grapes. Scientists could not confirm yet which type of ingredient made it poisonous for dogs, but some research says that the presence of tartaric acid in grapes is causing serious health issues.

In this article, I will discuss some of the “whys” and “whats” of the toxic relationship between dogs and grapes.

Can Dogs Eat Grapes

Can Dogs Eat Grapes?

No, dog’s cannot eat grapes. Grapes are well known for their toxicity in dogs. Grapes are very very dangerous for dogs. You should not even wait for symptoms, just take him to the vet even if he ate only one grape. Only one grape is enough for kidney failure or death.

You should be extra careful. Never store grapes where your dog can reach them easily. Always keep grapes out of the reach of your dogs.

If you were unaware and now when know that grapes are very toxic for dogs. If your dog ate grapes recently, then do not leave him untreated take him to the vet as soon as possible. This condition is also called “grape toxicity” which leads to acute kidney failure.

If you see your dog ate any of the grapes or raisins, sultanas or currants, immediately take you to the vet. Only your vet can suggest to you what to do in that situation.

What Are the Signs of Grape Poisoning in Dogs?

When you get to know that your dog has eaten grapes or even a single grape then without waiting call your vet straight away. DO NOT WAIT FOR THE SYMPTOMS TO APPEAR. Grapes poisoning happens very quickly in dogs. But if you do not know whether your dog has eaten grapes or not, I have mentioned some of the symptoms below.

While we consider dogs to be members of our family, feeding them the same food we eat can cause injury to them.” Stated in Hillspet.

Also below image represents food which are considered as poisonous or dangerous dog food[1]. Never feed any of these.

  • Lethargy, weakness, lethargy, and an uncharacteristic lack of movement.
  • Abdominal pain (a painful stomach when touched).
  • Dehydration- dry nose and mouth and excessive panting, pale gums. (You can check dog dehydration by pulling up the skin on the scruff of the neck. If it doesn’t spring back in place, your dog is likely to be dehydrated).
  • Vomiting and/or diarrhoea within a couple of hours.
  • Increased thirst is accompanied by either excess urination or depleted urination. In some cases, no urination at all due to kidney failure.

Wondering is kale good for dogs? While healthy in moderation, too much kale can cause issues. Check with your vet on adding kale safely.

Is It the Same for Raisins and Sultanas?

There is no doubt that raisins and sultanas affect dogs in the same way grapes do. Raisins and sultanas are dried versions of grapes. Therefore, the toxic ingredients are also there.

Many believe that dried versions like raisins and sultanas are more concentrated because they are dried, so the effect of raisins and sultanas is more dangerous than grapes. Hence, there is a BIG NO for grapes, raisins and sultanas[2].

You should also be a little careful about other food items you might give as treat to your dogs like biscuits or cake. Normally, they both contain the ingredients of grapes and so they become toxic also.

I strictly tell you to never feed raisins, sultanas or currants along with grapes. Contact your vet if your dog ate any of them or you served something which contains raisins, sultanas, currants, or grapes.

Just like grapes, raisins and sultanas, other fruits like raspberries can also be toxic to dogs, so it’s important to research can dogs eat raspberries before feeding them.


Can Grapes Kill Dogs?

If the dog doesn’t get immediate treatment then there are chances that the dog faces severe medical issues and in extreme cases, kidney failure can also happen.

Can a single grape be fatal?

Unfortunately, only one piece of grape is enough to create disaster for your dog. Which can go up to kidney failure or death if the dog doesn’t get treatment.

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

You might have heard or seen people feeding their dogs a few grapes and surprisingly they are unaffected. But even scientists cannot find the reason why dogs cannot have grapes. Therefore, instead of assuming that your dog might have immune to grapes, you should never feed grapes.

How to prevent dogs from having grapes?

Definitely, you should avoid the situation where you need to take your dog to the vet. You can simply store grapes and food items containing grapes out of his reach. secondly, you should eat grapes privately without dropping them. And keep your shopping away from your dog.


From now onward help every dog in your neighbour by spreading awareness of grapes toxicity. No one should search can dogs to eat grapes, as grapes are like a poison pill for dogs. You need to keep all the things containing grapes out of reach of your dogs. If your dog eats it accidentally, then the only thing you should do is immediately take your dog to the vet.

While grapes are toxic, there are many healthy human foods like bell pepper for dogs that are safe for dogs to eat in moderation. Check with your vet before introducing any new foods.
