Grapes are a juicy and flavorful fruit that most humans enjoy immensely, but can dogs eat grapes? Short answer is: No! Grapes are not a food that you can give to your dog. Even though many fruits and veggies are safe for dogs to consume, grapes are not on the list!

Why is that Star has to stay away from grapes? Before we get into details, both grapes and their dried counterpart, raisins, are not good for dogs. Let’s look at the reasons why.

Can dogs eat grapes?

Grapes are not safe for dogs, although the reason why is not exactly known. What is known, is that grapes, raisins, and currants may cause your dog to experience kidney failure. Whether the grapes are red, green, purple, dried into raisins, seeded or seedless, do not allow your pooch to eat grapes.

Let your family know that grapes are out of the picture as far as fresh fruit treats, and this ban on grapes includes grapes jellies and jams, and bagels with raisins. Even spilled wine is a hazard to your dog. Raisins are a dehydrated version of the grape and are just as toxic. Never let your dog have cereal with raisins, trail mix, or baked goods that contain raisins. 

Always look to healthy and safe options. Try your hand at making homemade dog treats. Your dog will be thrilled with the taste and you’ll know exactly what went into the treat. Apples, cheese, and chicken are tasty foods you can add as you bake dog-approved cookies.

Why are grapes toxic to dogs?

The reason why grapes can cause acute kidney failure is not clear. Research is underway, with a few theories at the top of the suspect list. 

It may be that compounds in the grape cause a decrease in blood flow to the kidneys, or that the toxins cannot be metabolized, causing issues with the kidneys. Either way, the chance of grapes toxicity if your dog eats grapes is high.

How many grapes are toxic? This is unknown — any amount is dangerous — and that’s because all dogs react differently.

Some canines will not react after eating several grapes or raisins, while others will become seriously ill after ingesting just a few raisins or grapes. There is no set amount and no way to know how grapes will affect your pooch.

If you suspect your dog has ingested grapes, no matter how many, consult the veterinarian.

What are the symptoms of grapes toxicity?

Symptoms of grapes poisoning can appear anywhere from 6-12 hours after your dog eats grapes or raisins. Grapes toxicity is an emergency that requires veterinary treatment as soon as possible. When you arrive at the clinic, let the veterinarian know what your dog’s activities have been. 

If you did not witness the incident but see grapes in the vomit or stool, let the veterinarian know. If your dog has possibly eaten a baked product, there could be currants or grape-based sweeteners in the product, causing toxicity. Provide as much information as you can.

You may see these symptoms: 

  • Diarrhea

  • Vomiting

  • Grapes or raisins in the stool or vomit

  • Loss of appetite

  • Lack of energy

  • Excessive thirst

  • Signs of stomach pain

  • Weakness

  • Lack of urine production

  • Tremors

How to avoid grapes poisoning:

Make sure that family members and visitors are aware of grapes poisoning. Keep bowls of grapes off the counter and don’t leave granola bars or trail mix within reach. If your pup is the type of curious canine to get into garbage, don’t let the opportunity arise. Also, check your backyard space for the presence of wild grape bushes.

Other foods toxic to dogs include:

  • Garlic

  • Chocolate

  • Macadamia nuts

  • Onions

  • Anything containing xylitol (chewing gum, candies)

  • Alcohol

What are safe fruit options for my dog?

If you are having a dog training session with your favorite four-legger, you can use fresh fruits as a reward.

Blueberries are a low-calorie fruit that many dogs love. They are low in sugar, too which is a bonus. Always look for berries without pits, such as raspberries, blackberries, and cranberries. Slices of peach are a good source of vitamin A, as are mangoes. 

When letting your dog sample these treats, be sure to throw the pit in the garbage as soon as you slice the fruit, to avoid your pupster choking on the pit.

A final note on grapes

Grapes toxicity can range anywhere from a mild case to a severe one. When treatment is received quickly after the ingestion of a few grapes, the outlook is good. But if your dog eats a large number of grapes and you are unaware or cannot get immediate treatment, the prognosis can be poor.

To keep your pooch safe, make sure that grapes are well out of reach and that your pooch is rewarded with treats that are safe, like homemade dog biscuits and vet-approved snacks.
