Can Dogs Eat Grapes? [Definitive Answer 2021]

Experts agree that no, dogs should not eat grapes in any amount whatsoever.

If a dog eats any type of grape (Red, Green or White), it will experience a multitude of terrible symptoms.

These symptoms include dehydration, changes in urination, vomiting, diarrhea, or a complete loss of appetite.

If a dog ingests a large number of grapes in relation to its body mass, it can quickly develop kidney failure and die.

If you suspect that your dog consumed grapes, do not wait!

Take your pet to the veterinarian as soon as possible. Meantime, you can contact from pet helpline (888) 426-4435 (ASPCA).

Depending on the number of grapes your dog ate, the veterinarian may give them extra fluids through an IV (Intravenous fluids).

Also, provide them with medicine to prevent kidney damage.

Why can’t dogs eat grapes?

Why can’t dogs eat grapes

You may love your furry friend and want to share your food with them every time you eat a snack or meal.

However, if you snack on grapes, you should never give them to your dog.

Grapes are poisonous to dogs, and if they end up ingesting a certain number of grapes, they can die.

No matter your dog’s age or breed, feeding grapes to your four-legged companion is guaranteed to cause a significant amount of gastrointestinal pain, exhaustion, and loss of appetite. 

Additionally, dog owners should be aware that any products that contain grapes are equally as harmful.

When we say a grape product, we mean any food product with grapes in its ingredients list; any product made with grapes is dangerous for your dog to consume. 

To many people, the first product that comes to mind when they think of grapes is wine. This is a large reason why giving animals wine—or any other type of alcohol, for that matter—is dangerous and unhealthy. 

Refraining from giving your dog wine might be obvious; however, there are plenty of other products that contain grapes that owners might not consider.

Many people may not think twice about giving their dogs raisins or products that contain raisins.

However, as raisins are simply dehydrated grapes, you should never feed them to your pooch.

This is because they can experience the same effects as if they were eating grapes.

Scientists have discovered that grapes are poisonous to dogs

how eating grapes affects your dog

You may be wondering how eating grapes affects your dog.

Unfortunately, veterinarians and animal scientists don’t know the exact mechanics that occur within a dog’s system when they eat grapes.

Despite this, it is indisputable that grape poisoning is a widespread problem.

Also, a concept that was finally realized by the veterinary field less than 30 years ago.

By compiling all of the information and cases surrounding animals’ premature deaths, scientists and statisticians organized and discovered new substances that caused premature death in animals.

One of the links that were found was the deadly link between dogs and grapes.

For a long time, chocolate was the only poison that was known to kill dogs. However, this new database also linked grapes, raisins, currants, macadamia nuts, caffeine, garlic, onions, and milk to dog poisoning cases.

What happens if a dog eats a grape

As we already mentioned, ingesting too many grapes in a single serving can kill your dog.

But, how fast does a serving of grapes affect a dog, and what is the timeline of their poisoning symptoms?

Thirty minutes to an hour after your dog eats grapes, you will notice nothing out of the ordinary in your dog’s behavior.

Your dog may seem fine because the grapes in their stomach have yet to digest.

After the grapes break down and absorb into the dog’s system, they will begin affecting your pet’s intestines

After 4 hours, you might start to see your dog pant heavily as if they are under the hot sun.

They may begin vomiting shortly after they start panting. Some dogs only vomit once, while other dogs vomit continuously.

At this point, you might misdiagnose their symptoms.

It may just look like they ate something that they should not have.

Or you may assume that the can of food that they ate from was old.

It is within the next 20 hours that you’ll see a big change in your dog.

They will become very confused, listless, and have absolutely no energy. You will see an increase in your dog’s panting, but they may be too tired even to drink water.

During this period, dogs can also vomit a second time. 

Surprisingly, the symptoms of grape poisoning are also commonly associated with dogs who are experiencing heatstroke

After a full 24 hours, if your dog has not yet improved, you absolutely must take them to the vet.

If the symptoms continue to the next day, this could mean that your dog is now experiencing acute kidney poisoning, and their kidneys are beginning to shut down.

How to know if your dog is suffering from grape poisoning?

How to know if your dog is suffering from grape poisoning

Although every dog experiences grape poisoning differently, there are a few common symptoms that you can look out for in order to determine the severity of the poisoning.

Some of these observable symptoms include:

  • Abdominal pain and pain when picked up.
  • Changes in the amount that they urinate or drink water.
  • Continuous vomiting or diarrhea.
  • Loss of energy.
  • No longer eating or drinking water.
  • No longer being able to perform everyday activities like jumping, running, or rolling over.
  • Increased panting and dehydration.

If you see your dog exhibiting any of these behaviors, it is more than likely that they are experiencing severe grape poisoning.

If you see your dog eating grapes…

First, you must pull the grapes out of your dog’s mouth.

Even if you have to pry their mouth open and stick your hand into your dog’s mouth, it is essential to prevent them from swallowing the grapes.

By prying the grapes out of their mouth, you can prevent your dog from dying.

If your dog ate grapes before you were able to stop them or you did not know about the incident, you must force your dog to vomit up the grapes before they completely digest

Once you have removed the grapes from your dog’s mouth, immediately call your veterinarian or a pet helpline (888) 426-4435 ASPCA Poison Control Center.

Inform the operator of your situation.

You will also need to provide the operator with additional information, such as an estimation of how many hours ago you saw your dog eating grapes.

The operator’s response can differ greatly depending on how long it has been since your dog initially ate the grapes.

Remember that grapes are poisonous; your immediate action is necessary.

You have far more treatment options for your dog if the incident occurred one hour ago than if it happened four to five hours ago.

Many veterinary websites suggest that if you suspect your dog has ingested grapes recently, you must immediately make your dog vomit.

Vomiting will eject the grapes out of their stomach and prevent the grape’s harmful compounds from entering your dog’s system.

Ways to make your dog vomit

According to the American Kennel Club, hydrogen peroxide, the chemical that humans commonly use to clean cuts and scrapes, is a liquid that can induce vomiting in dogs.

Hydrogen peroxide should be your go-to method to force your dog to vomit because it is cheap, and many people already have it in their homes.

When a dog swallows hydrogen peroxide, the foam from the liquid will irritate the dog’s stomach and induce their vomiting reflex.

It may seem dangerous to a dog owner to force their dog to swallow hydrogen peroxide, but it is not poisonous to dogs.

Be aware that the more hydrogen peroxide your dog ingests, the more they will vomit.

Before you force your dog to swallow hydrogen peroxide, make sure they are outside or in an area that can be easily cleaned. 


Do not force your dog to ingest hydrogen peroxide if they have already developed shallow breathing. 

At that point, do not attempt to help your dog at home and instead take them to the veterinarian where they can receive emergency medical assistance. 

Forcing your dog to vomit when they can't catch their breath can suffocate them, especially when they are not under professional veterinary supervision. 

After your dog vomits or if you suspect your dog ate grapes

hurry them to a veterinarian

Whether or not you have witnessed your pet vomiting, place your dog on a leash and hurry them to a veterinarian.

If it is late in the evening and your usual veterinary clinic is closed, you can instead take your dog to an emergency veterinarian that operates at night.

The veterinarian will then evaluate your dog, examining their behavior and symptoms. 

As a precaution, you should already have an emergency veterinarian that you are familiar with.

Do not wait until your dog is poisoned to look through a list of emergency animal care establishments. 

Take an hour out of your routine and research the emergency veterinarians in your area.

If you have animal insurance, you can call all of the emergency vets that you are interested in and see which establishments will take your insurance.

How many grapes can hurt a dog?

developing intense vomiting and dehydration

Because dogs come in many different breeds, sizes, and shapes, it is hard to pinpoint the number of grapes it takes to poison or kill a dog. 

Some dogs can eat a small number of grapes (1-2) without any negative side effects whatsoever.

However, other dogs could only eat one grape before developing intense vomiting and dehydration. 

According to, for some dogs, it only takes 0.3 ounces of grapes to cause kidney failure.

If you have a 10 lb. dog, they can develop kidney failure if they eat only 3 oz of grapes, which is equal to about 20 grapes.

However, since the amount is so small, even just ten grapes can cause painful symptoms like abdominal issues, dehydration, and diarrhea.

To prevent terrible suffering and irreversible complications, stop feeding your dog grapes completely.

Whether you were feeding them grapes all their lives or recently started to, nothing good comes from feeding your dog grapes or grape products.

Instead, you can feed your dog other dog-safe foods like chicken, beef, steak, celery, carrots, pork, peas, hard cheeses, buffalo meat, raspberries, and many other foods.

My dog ate grapes but seems fine

My dog ate grapes but seems fine

No matter the number of grapes your dog ingests, there is no such thing as a dog that can safely eat grapes.

If you have been giving your dog grapes but you notice no behavioral changes, it could mean that your dog doesn’t show any outward symptoms of grape poisoning.

It is still possible that your dog’s internal organs are causing them a great deal of pain.

If you have mistakenly fed your dog grapes, watch them for the next 24 hours, and ask yourself these questions:

  1. Does my dog become angry if I try to pick them up?
  2. Are they drinking more water than usual?
  3. Are they urinating more or less than usual?
  4. Do they become confused and tired after eating?

As grapes also cause kidney failure, feeding your dog grapes little by little can likely cause their kidneys to shut down over a longer period of time. 

If you had been feeding grapes to your dog for their entire life, you should take them to the veterinarian to check their blood and kidneys.

You should also tell the veterinarian what you have been doing.

Let the veterinarian know that you did not realize grapes were poisonous to dogs, but now that you are aware of the danger, you wish to make sure there’s no long-term damage occurring within your furry friend.


It is theorized that some dogs may be able to eat small amounts of grapes without long-term effects.

Despite this, the dangers of eating grapes are far too great to take the risk.

Dog owners are recommended to completely eliminate grapes from their pets’ diets.

If your dog has accidentally ingested grapes within the last hour, do your best to make them vomit by forcing them to ingest hydrogen peroxide through a funnel.

If you cannot make them vomit or it has been more than an hour since they ingested grapes, take your dog to the veterinarian immediately.

Your veterinarian will provide your dog with any medications or treatment they need to prevent long-term damage to their internal organs, like their stomach or kidneys.
