Grapes and grape containing products are poisonous to dogs. This includes grape jelly or juice, as well as dried grapes (raisins), and even currants which belong to the same family as grapes. The mechanism of poisoning is currently unknown, but grape poisoning can cause severe kidney failure in dogs. Most studies suggest that the toxic dose is about 32 grams per kilogram of the dog’s weight for grapes and 11-30 grams for raisins, however symptoms of poisoning can sometimes be present even at very low doses. No amount of grape containing products are considered safe for dogs.
The toxin can be found in all types of grapes, including seeded, seedless, organic, and those used for wine. Vomiting and diarrhea are the initial signs of grape toxicity, beginning about 6-12 hours after ingestion. This is followed by general lack of energy, weakness, dehydration, thirst, and failure to produce an adequate amount of urine. Fatal kidney dysfunction will develop in 1-3 days. If vomiting is induced 15-20 minutes after ingestion this can help to reduce absorption and limit the severity of the symptoms. Once kidney dysfunction is present intensive fluid treatment will be necessary to save your dog’s life. Large doses may end up being fatal even with treatment.
Grapes contain a toxin that causes kidney failure in dogs. Grapes, raisins, and grape containing products will all make a dog very sick when ingested. This is called grape poisoning or grape toxicity. Immediate treatment is necessary and some cases can still end up being fatal.

These are the most common risk factors associated with grape poisoning.

Diagnosis of grape toxicity is based on a history of grape ingestion, symptoms, and a blood test. Pieces of undigested grapes in the vomit or feces may be the best indication if you didn’t see the incident, especially when this is combined with lethargy, general weakness, and lack of appetite. If you’re not sure, a history of your dog’s activities may be helpful. If you think your dog has ingested a baked product, you should check the list of ingredients for currents or grape-based sweeteners and bring a sample along for the veterinarian to examine. In the later stages, a blood test will show kidney failure with increases in BUN (blood urea nitrogen), as well as creatinine, phosphorus, and calcium. The veterinarian will need to rule out other toxicities which could also cause kidney failure, especially if the poisoning incident was unobserved.

If you think your dog has been poisoned, it’s a good idea to call a poison help-line for instructions on immediate treatment. Follow the advice of the agent exactly and take your dog to see a veterinarian as soon as possible.
If the poisoning took place within the last two hours, the veterinarian will try to induce emesis and reduce further absorption. Gastric lavage may be carried out under anesthesia. Activated charcoal will also be given since this medication binds to the toxin in the dog’s stomach and also helps to limit absorption. For mild cases that are discovered immediately this may be all the treatment that is needed.
If your dog has ingested a large amount of grapes or grape containing product intravenous fluids will be necessary for at least 48 hours. This will help to increase urine production, support kidney function and flush the toxin out of the body. If the dog is still only producing a very small amount of urine, further medications may be necessary to stimulate the kidneys. If the kidneys have stopped producing urine altogether the incident will usually end up being fatal.

The level of toxicity in grapes is considered mild to severe. Dogs may recover from low doses that are treated immediately, but large amounts have a poor prognosis. Immediate treatment can increase your dog’s chance of survival.Any amount of grapes or grape containing product is dangerous for dogs, so the best way to manage the condition is to avoid exposure. Don’t leave out open containers of grapes or raisins. Put spoiled grapes through a food processor rather than disposing of them in the trash, and don’t give you dog any foods designed for humans. Keep your dog away from dumpsters, especially those associated with grocery stores which could contain large amounts of spoiled grapes. Protect currant bushes in your garden and be aware of any grapes growing wild around your house. This is especially true if your dog tends to eat everything. Most dogs will avoid poisonous plants in the wild, but domestic dogs that are more used to eating human food may not have this instinct.

My 45 lb dog ate about 20 grapes 46 hours ago. She threw up a small amount yesterday but is acting fine. Drinking/eating popping/peeing normal. Is it safe to say she will be okay?

Hello, grapes cause issues with the kidney you may not toxic these changes right away. If she is otherwise acting okay the acute toxic effects would be gone. Your vet can check bloodwork to see if there are any issues with the kidneys

Thank you for your question. To some dogs, grapes can be very toxic, and can cause kidney failure. If your dog is showing any signs of vomiting, diarrhea, lethargy or a loss of appetite, it would be best to have her seen by your veterinarian right away. I hope that all goes well for her!

I have one malamute (8 months) and a husky (5 months.) they both ingested about 10 grapes each (give or take) after they fell on the floor. I immediately rushed them to emergency. They induced vomiting but then re assured me that the dosage amount isn’t enough to hurt them and that keeping them there for IV fluid was unnecessary. My older girl threw up today but it was a very very tiny amount. Other than that, they both have been doing great. Should I still be concerned?

Thank you for your question. The unfortunate thing with grape toxicity is that there actually isn't a dose. Some dogs react badly and some dogs don't. Some dogs can have as many grapes as they want, and some dogs will go into kidney failure from one grape. Since they did induce vomiting, they may have gotten all of the stomach contents out, and the grapes may not even be a problem right now. Since one of your dogs is vomiting, however, I think that I would go back, and have a kidney profile run to check kidney enzymes. If either of their kidney enzymes are elevated, then I would probably put them on IV fluids and keep them there. If you are able to get in to see your regular veterinarian, you could likely take that route as well. If they are both bright and happy and acting normally, I'm not sure that you need to go back to the ER, and you could probably go to see your veterinarian as soon as they open in the morning. I hope that both dogs are okay and everything goes well.

This is my first dog and by accident a friend fed him 1 grape. As soon as I saw I tried to tickle his throat to make him vomit but it didn’t work, I called the vet hotline and they advised me to takw him to the clinic immediately and didnt recommend hydrogen peroxide from home due to his nose being more pushed in. I called the vet and unfortunately it was to expensive at the time for me to take him in, but ever since it happened he has not showed any symptoms but it has only been 1 day so far. Still monitoring him closely. Hopefully at his check up we can run a blood test to check his kidneys! But I am really scared.

We have a 5-month-old Husky that weighs 39 pounds, he ended up tipping a bowl of grapes and eat some of them, not suer like 7-8. I was upstairs and did not realize that there was a bowl of grapes in which it did not have many I did take him to vet today, they did induce the vomit and some grapes did come out and I am hoping that he fully recovers. What is a recovery time for a Husky as I have been worried and need some advice? He did not throw up after eating, seemed pretty active but still concerened

I'm a first time dog owner and also did not know the danger of grapes. I've given my shih stzu a grape here and there. The last time was about 2 weeks ago, he had one. The only concerning symptom was that he threw up earlier this week once. Not sure if it is related to the grape consumption from 2 weeks ago. He eats anything and everything he find on the ground. He hasn't shown any other symptoms. Very playful, still eating normal, going potty normal. Just worried if there could be long term effects? I called my vet today to ask. The visit is $50 and the blood work to check his levels is $110. Not sure if I should be taking him in since he hasn't shown any other symptoms? Really can't afford to pay that much for peace of mind, but we love our dog. I'm lost!
