Can Dogs Eat Grapes

It’s just so easy to want to give your dog a piece of whatever human food you are snacking on. One common food, grapes, are often in question. What could go wrong with feeding your dog a juicy grape, right? Read this article first, because can dogs eat grapes safely? You may be surprised!

Dr. Jess explains the answer below:

Dog food experts have arguments regarding the safety of serving grapes to dogs.

Well, as delicious as grapes are, is it actually a health threat to the dogs or are we over-reacting about this?

Let me, the veterinarian, explain my thoughts…

It’s always the best idea to double-check which foods your dog can and can not eat because many foods that are safe and healthy for humans are actually very harmful for your dog to eat, or even poisonous or deadly to them. Taste is never worth the risk of harming your pet.

That’s why I am so glad that you are here making an informed decision before feeding your dog grapes!

What Do Dogs Eat?

Some dogs are not picky at all about what they eat. They’ll eat whatever you offer them- they’re like vacuum cleaners sucking up anything you put in front of them and then some!

Some dogs are on the pickier side of things. Pickier pups can be harder to properly feed because they just won’t eat any food we give them. Try feeding a picky dog something like okra!

A common canine diet for pet dogs consists of a complete dry or wet feed and possibly some form of supplements in some specific cases (however, not all pet dogs need supplements).

Foraging can also be included in the diet if the dog is allowed to roam, or the dog is feral, and of course there are treats that are a part of many dog’s diets!

The diet of every dog breed will very when you are looking into a healthy and complete diet for your pup. So it is important to know when offering food to your dog, what constitutes a healthy choice, and what does not.

An improper diet could put your dog at risk of having problems properly digesting their food and absorbing nutrients correctly. And we don’t want that now do we???

So let’s talk specifically about kiwis, since that’s why you clicked over here today, and talk about how it could affect your dog’s overall health and well-being.

What Are Grapes?

Grapes are a type of berry, which is a fruit, that grow typically in clusters on vines.

They come in all different sizes, colors, shapes, and tastes.

There are over 8,000 varieties of grapes grown across the world.

Types of Grapes:

There are cultivated and wild grapes. Cultivated grapes are grown commercially, the source of many store-bought grapes.

Grapes can contain seeds or be seedless, be green all the way to dark red in color, and have thin to extremely thick skins.

Some grapes are used to make wines, while others, like table grapes, are to be eaten while fresh and tight, while others are dried and turned into raisins.

Grape Nutrition Breakdown:

Grapes should not be fed to dogs – and I’ll discuss the reasons why a little bit farther down in this article.

However, grapes do have some health benefits when looking at their composition. So you may hear some people tell you that grapes have the potential to be good for dogs.

Even though grapes have some healthy qualities, please do NOT feed your dog grapes or raisins…. ever!

Grapes are a good source of potassium and fiber, and a source of multiple different vitamins, including vitamin C.

According to Medical News Today, grapes can do some pretty wonderful things for humans:

“The nutrients in grapes offer a number of possible health benefits. They have been associated with prevention of cancer, heart disease, high blood pressure, and constipation.”

Grapes have high water and high fructose (sugar) content.

Sugar Levels:

With how tasty they taste, it shouldn’t come as any surprise that grapes contain quite a bit of sugar, but not as much sugar as some other fruit choices contain.

Too much sugar can cause health concerns such as obesity or diabetes in your dog, so this is yet another reason why you shouldn’t feed your dog this food.

Are Grapes Harmful to Dogs?

Yes, they definitely are harmful to dogs.

Grapes and raisins are highly toxic to dogs. They affect the kidneys very quickly in a condition called acute renal failure.

What is Canine Acute Renal Failure?

Acute renal failure can be broken down like this:

  • Canine = “dog”
  • Acute = “fast” or “quick
  • Renal = “kidney
  • Failure = “Decrease/halting of function

Therefore, acute renal failure due to grape or raisin poisoning is a quick-onset of kidney disfunction where the kidneys stop working properly. This condition is very serious and can be lethal within days or hours of onset without rapid treatment.

Research has yet to prove exactly which substance in the grape itself causes this toxic reaction within dogs. But we do know that grapes and raisins are very toxic to your canine companion.

Will One Grape Hurt My Dog?

Even the ingestion of one single grape or raisin can be fatal to them. Consuming a grape or raisin can lead to acute (fast or sudden) kidney failure in dogs. They can very sick very fast!

This can lead to a multitude of problems including things like dehydration and electrolyte imbalances that could impart a trip to the veterinary clinic for your vet to fix.

The higher sugar content in grapes can also lead to some pretty big health concerns as well.

Not only does excess sugar leave your dog prone to weight gain and obesity, but also diabetes and gastrointestinal (digestive) upset due to the sugar-overload in their systems.

These are just a few reasons as to why you should NEVER feed your dog a single grape or raisin!

How Can Grapes Be Harmful to Dogs?

Before we can decide whether grapes are harmful to feed our dogs (spoiler alert – grapes and raisins are very harmful for your dog!), we need to first understand some of the risks involved if we do feed our dogs the fruit.

These are a few of the factors to keep in mind besides the deadly canine acute renal failure discussed above:

Harmful Reason #1: Loose Stool/Diarrhea

Too much fiber or new foods in the diet can mean hypermotile, or increased movement, of one’s digestive tract.

Some dogs are more sensitive to additional fiber or new foods in their diets, so they are more likely to have loose stool and in some cases, full-blown diarrhea.

Other dogs will not be impacted by any additional fiber in their diets.

Now, I have not seen this last scenario with my own eyes, I have had many people tell me that that was their experience.

Harmful Reason #2: Allergic Reaction to Grapes

A dog can develop an intolerance or an allergy to any food, so there is always the possibility that your dog is allergic to grapes.

If you suspect your dog is allergic to grapes do NOT feed it to your dog.

If your dog is allergic to grapes and accidentally ingests it, go to your nearest animal emergency room immediately.

When this happens, the attack sets off a hypersensitivity reaction and can result in any of the following symptoms:

Common symptoms of adverse/allergic reaction to food:

  • Nausea/vomiting
  • Diarrhea
  • Itching/Increased grooming
  • Fever
  • Lethargy
  • etc.

Can Puppies and Juvenile Dogs Eat Grapes?

The risk of becoming sick from a grape or raisin has no dependency on age, sex, or breed of the dog, so you shouldn’t be giving your pup grapes or raisins ever.

Compared to their adult counterparts, puppies have much more sensitive gastrointestinal systems.

Avoid feeding baby dogs any kinds of fruits and vegetables until they reach 12 weeks of age to allow their stomachs to mature with them.

Remember – baby and young, and juvenile dogs have more sensitive digestive systems!

Can Dogs Eat Seedless Grapes?

No, your dog can not eat seedless grape pieces.

Can Dogs Have Grape Juice?

Absolutely not. Grape juice contains grapes and usually extra sugar, both of which are not healthy for your dog.

Medical & Health Concerns of Feeding Grapes to Dogs:

Grapes might be bad for your pet? Yes yes yes! Do not feed your dog grapes. Remember that grapes and raisins are highly toxic to dogs.

If you need any more reason not to feed your dog grapes, here are a few other less toxic reasons that grapes can be bad for your pup:

  • Pesticides: Grapes should always be washed to make sure they are free of any pesticides or chemicals that could be harmful to dogs.
  • Parasites: Grapes should be checked over for parasites that can lead to potential parasite problems with your dog.
  • High Sugar Levels: Grapes contain natural sugars in them. Therefore, too many grapes means your dog is getting a lot of unnecessary additional sugar – not a good idea for your dog’s health, especially if they are overweight or have metabolic issues, things like diabetes!
  • Overly Ripened: Avoid rotten fruits and vegetables that can cause diarrhea and gastrointestinal upset.
  • Baby Puppies: Puppies have a more sensitive digestive system than their adult counterparts do, and therefore you shouldn’t give your rabbit friend any fruits or vegetables.

How To Feed Grapes To Your Dog:

You don’t. You NEVER feed grapes or raisins to your dog.

Keep the following in mind when serving food to your dog:

And remember that dogs need something other than a bowl or plate of fruit or other human foods – they need a complete and balanced diet.

Whichever complete food you choose for your dog, it needs to have the AAFCO label indicating the diet is complete and balanced for your dog’s life stage.

AAFCO approved foods have gone through testing and compliance to make sure that the diet is safe and healthy for your pet.

Dogs already get everything that they need from their kibble or canned food.

What to do If Your Dog Eats Grapes Accidentally:

If your dog ingests grapes or raisins, contact your veterinarian right away. 

Your vet will want to discuss details and will tell you what to do next.  You will likely need to move quickly to give your canine the best possible chance of recovering and surviving after treatment.

We vets want to help and we will best help if we are notified right away.

Trust me, us vets are happy to help!

Summary:

Dogs can not have grapes, even if they are ripe, clean grapes, and even if they are fed in moderation. Nope – do not feed grapes to your dog.

Too many grapes can cause a number of health problems for your dog, the largest issue is severe toxicity which can lead to acute renal (kidney) failure.

Do not feed young, growing dogs or dogs with underlying health conditions grapes even as a treat. They can see all kinds of issues, just like adult dogs can.

If you have questions regarding feeding your dog grapes, contact your local veterinarian. They will likely agree with me 🙂 Just don’t do it.
