Dogs are beloved by many and can be the best and most loyal companions – however, even with the best intentions, owners should always be aware of what their furry friends can’t have.

Dogs love to eat human food but unfortunately grapes are not a good choice for them. It’s important to know how many grapes are toxic to dogs so that they stay safe and healthy while giving them treats or snacks.

Why Are Grapes Toxic to Dogs?

Grapes contain a variety of compounds that may be toxic to dogs and other animals. Tannins, flavonoids, and monosaccharides are the main components responsible for toxicity in grapes. These compounds are not easily metabolized by dogs, so they accumulate in their bodies over time.

As a result, excessive consumption of grapes can lead to serious health problems such as kidney failure, anemia, and liver damage. The toxicity of grapes increases when they are dried or concentrated in raisins or wines, so even small amounts can be harmful to dogs.

In addition to the toxins contained in grapes, some other possible causes for grape poisoning include pesticides used on the grapes, mold or fungus contamination, or the presence of other toxic substances in the grapes. It is important to only give your dog fresh and organic grapes, as these will be free from any additional toxins.

It’s also important to note that not all dogs are affected by grapes in the same way. Some may have a higher tolerance to the toxins, while others may experience more severe reactions. As always, it’s best to consult with your veterinarian before feeding your dog any type of food.

How Many Grapes Are Toxic to Dogs?

Grapes and raisins are potentially toxic to dogs. In most cases, even small amounts of grapes or raisins can cause serious problems for your pet. It is important that you do not give your dog any grapes or raisins, no matter how few.

The exact amount of grapes or raisins that is toxic to dogs is unknown, but the dose that can cause serious problems for a small dog is 0.7 ounces per kilogram of grapes, or 0.1 ounce per kilogram of raisins. Symptoms of grape or raisin toxicity include vomiting, diarrhea, abdominal pain, lethargy and anorexia.

If your pet has consumed any grapes or raisins, contact your veterinarian immediately for treatment. In some cases, early intervention can be life-saving. It is best to err on the side of caution and keep all grapes and raisins away from your pet. 

How to Treat Grape Toxicity in Dogs

If you suspect your pet has ingested grapes or raisins, contact your veterinarian right away. Treatment for grape toxicity in dogs usually involves inducing vomiting and providing supportive care until the toxins leave the body. Your vet will likely give your dog activated charcoal to help absorb the toxins before they can enter the bloodstream. They may also prescribe medications such as intravenous fluids to help flush the toxins from your pet’s system, and medications to reduce any nausea or vomiting.

In some cases, pets with grape toxicity may need to be hospitalized for observation and additional supportive care. If left untreated, grape toxicity can lead to serious complications such as kidney failure. However, with prompt treatment, many pets make a full recovery.

It’s important to remember that prevention is the best treatment for grape toxicity in dogs. Grapes, raisins and other products containing them should be kept out of reach of pets at all times. Be sure to also double-check ingredient lists on food labels as grapes can sometimes be hidden sources of toxicity.

How to Prevent Dogs from Eating Grapes

The best way to prevent your dog from eating grapes is to keep them out of reach. Store grapes in a place that is not accessible to your pup, such as in the refrigerator or on a high shelf. If you’re keeping grapes out for snacking, make sure they are securely contained and stored away when not being monitored. Additionally, make sure that any foods or snacks around grapes are safely out of reach as well.

Another way to prevent your dog from eating grapes is to supervise them when they are outside or in the same room as grapes. With supervision, you can stop them from eating the fruit before they have a chance to consume it. You can also use verbal commands, such as “Leave it!” or “No!” to discourage them from trying to eat grapes.

Finally, training is an effective way to prevent your dog from eating grapes. If you can teach your pup proper behaviors and commands, it will be easier for you to control their behavior when they are around grapes or other potentially toxic foods.

You can also use positive reinforcement, such as treats and verbal praise, when they obey commands to stay away from grapes and other potentially toxic foods. With training and reinforcement, your pup will learn not to eat grapes or other potentially dangerous snacks.

Where Can I Find More Information about Toxic Foods for Dogs?

In addition, there are many books and other resources available from pet stores and online retailers that provide comprehensive information on safe and unsafe foods for dogs. Many of these books will include lists of toxic foods for dogs and provide information on how to identify and avoid them.

Finally, you should always consult with your veterinarian when changing or introducing a new food into your dog’s diet. Your vet can help you determine which foods are safe and appropriate for your pet and advise you on the best way to feed them. By doing your research and consulting with a vet, you can make sure your pet stays healthy and happy.


In conclusion, grapes and raisins can be toxic to dogs, even in small amounts.
