What is Raisins Poisoning?

If your dog eats any amount of grapes or raisins, take him to the veterinarian or animal hospital immediately. However, if it has only been a few minutes since your dog ate the raisins, and you cannot get to a hospital right away, you should induce vomiting. A solution of one teaspoon of hydrogen peroxide per five pounds of your dog’s weight should produce vomiting within 10 to 15 minutes. It that does not work, you can try it one more time with the same amount of peroxide. Do not repeat this step more than three times in 30 minutes. If your dog still has not vomited, you need to get him to a medical professional right away. It is a life-threatening emergency and needs immediate treatment.

Your dog will develop gastrointestinal irritation and vomiting in the first few hours of consumption, and within one to three days, signs of kidney failure will be obvious if your dog is not treated. These signs include loss of appetite, abdominal tenderness, fluid retention, tremors, extreme weakness, excessive thirst, and energy loss. This can affect dogs of any breed, gender, age, or size. If your dog has eaten any amount of raisins or grapes, you should go to a veterinarian or animal hospital immediately, even if you do not see any symptoms. Failure to do so can quickly lead to kidney failure, and can even be fatal.

Raisin poisoning in dogs is a serious disorder and can possibly result in acute renal (kidney) failure and death. Although the way in which raisins are toxic to dogs is still considered to be unknown, there are several theories, such as mycotoxin (a toxic mold or fungus), metabolic disturbance, or an idiosyncratic reaction (rare).

Causes of Raisins Poisoning in Dogs

The cause of raisin poisoning is the consumption of a toxic amount of raisins or grapes. The amount that is toxic to your dog depends on weight. The toxic dosage of raisins is determined by the formula 11-30 grapes per kilogram (0.18 to 0.48 ounces per pound) and 32 grams of grapes per kilogram of body weight (0.5 ounces per pound) for grapes. The best thing to do is not feed your dog raisins or grapes at all and keep them out of reach at all times.

Diagnosis of Raisins Poisoning in Dogs

The veterinarian will first stabilize your dog. He will try to induce vomiting with apomorphine, and perform a gastric lavage, which is done by washing out your dog’s stomach with a sterile solution through a tube in his throat. Activated charcoal will also sometimes be used to absorb any toxins that are left in your dog’s stomach. There is no definitive test for raisin or grape poisoning, but your veterinarian may be able to find evidence of grapes or raisins undigested in your dog’s mouth or throat. A complete physical examination will be done which includes body temperature, heart rate, respirations, weight, height, and reflexes. The veterinarian will palpate the abdomen to determine inflammation of the kidneys or stomach. A complete blood count (CBC) will be done as well as blood biochemistry analysis, blood gas assay, and urinalysis will be done. The veterinarian will get some images with x-rays of the abdomen to determine the amount of kidney damage your dog has.

Treatment of Raisins Poisoning in Dogs

After gastric lavage and charcoal treatment, the veterinarian will want to hospitalize your dog for IV fluids and observation for about 48 hours to prevent kidney failure. If your dog is not producing urine, dialysis will be used to remove waste and water from the blood to support the kidneys. Blood chemistry values, including renal enzymes, calcium, phosphorus, sodium, and potassium levels should be monitored for 72 hours. Medications such as furosemide, dopamine, or mannitol can be used in anuric renal failure. Hemodialysis or peritoneal dialysis may be of benefit if available. Basic supportive care and monitoring during hospitalization are important.

Recovery of Raisins Poisoning in Dogs

Prognosis depends on many factors. The condition of your dog when arriving, the success of decontamination. The progression of clinical signs can help determinethe outcome. Prognosis is favorable if the kidneys remain intact and supportivecare is given right away. If your dog is not urinating, the prognosis is poor. The prognosis is guarded in any dog developing symptoms of toxicosis.

Thank you for your question. Raisins are a strange toxin, as we don't know which dogs are affected. Some dogs can eat grapes and raisins with no problem, and some will go into kidney failure and likely die. Since we cannot tell, it is best to have your dog seen by a veterinarian right away, and start on IV fluid therapy for 2-3 days. They will probably want to check kidney lab values throughout the visit to make sure that your dog is maintaining kidney function. I hope that your dog is okay.

Hello, She may be just fine. One raisin can cause some issues such as vomiting or diarrhea. The toxic level of grapes and raisins is different for each dog. If your dog is acting lethargic or vomiting, it would be best to take him to your local emergency clinic.

Our 40 pound Brittany ate 8 - 10 raisins about 50 minutes ago. Now I realize that raisins are toxic to dogs. Should I be concerned? If so, what action should I take? Should I induce vomiting?

Hello- Unfortunately there is no known non toxic amount of raisins in dogs. Some dogs eat a very small number and experience renal failure and others may eat several and not have side effects. I would recommend taking her to your veterinarian or an emergency veterinarian immediately so they can give her a medication called apomorphine to make her vomit up the raisins. Hopefully she will and then that will be the end of it. Take care!

My dog might have eaten raisins. The box looked mostly undisturbed, but he chews everything so I don't have any idea how many he may have eaten.

Thank you for your question. Raisins are a strange toxin, as some dogs are affected and some dogs are not, but we don't know which dogs are going to be affected. It would be best to have your dog seen by a veterinarian right away, if that means going to an ER then that is what I would do, and they will do some blood work, possibly hospitalize him, and monitor his kidney values. I hope that all goes well for him and he is okay.

My small chi mix ate about 10 chocolate covered raisins, he hasn’t vomited yet. I did not induce vomiting due to no peroxide on hand. He’s under 6 pounds any help you could give I would be so thankful, it’s been about 30min and no weird symptoms

Thank you for your question. It would be best to take him immediately to the nearest open veterinary clinic and have them induce vomiting. Getting the chocolate and the raisins out of his system is going to prevent many serious potential problems. We typically have a window of about 2 hours to induce vomiting.

Vomiting

My 80 lb Labrdoodle ate roughly 1 pound raisins. We noticed roughly after one hour after he ate them. I called the vet and they suggested to induce vomiting using hydrogen peroxide. We tried that twice and since he did not vomit, we rushed him to emergency vet hospital. By then, it was already 3 hours since he ate them. They took him inside and had induced the vomiting. They kept him for few hours and sent him back. He was quite active and did not show nay signs of distress. Next day, he threw up once, but there were no raisins. Soon after that he was all normal. We waited for 48 hours and took him to vet for the blood test. All his tests were normal. He since then is eating, walking, playing, sleeping, pooping and urinating well. My husband found almost 200 raising in his poop all together. It's now been 5 full days and he seems to be alright doing everything he did before. I am still worried. Is there anything I should be doing now to ensure his kidneys are fine? Should I take him to vet again? Please advise.

My 30 lb cocker Spaniel, Pepper, ate 1/2 cup to a whole cup of raisin's by eating a whole loaf of pumpkin raisin bread my mother made. I didn't exactly know how long it had been since he had gotten into it. I took him to the emergency vet and they want $1200 to keep him for two days. They induced vomiting and said A LOT of raisins came up. They gave him a blood test and everything came back okay. He has anxiety and and been howling at night and so they have been giving him a sedative to calm him. I feel just terrible because he has gotten into lots of crap he shouldn't eat and has been fine. He ate a whole DARK Chocolate bar off the counter before and didn't even get sick. Anyways, I don't like keeping him there over night. They gave him IV fluids and want to do another blood test after 24 hours and then again the next day with more IV fluids and a blood test. The blood test are $130 each. Is it necessary to do them everyday while they have him? Also, if the second test comes back and nothing had elevated at all, and he is urinating fine, I believe I should bring him home. I mean, how much of a difference is one more day of fluids and monitoring going to do? I can monitoring him here. They can give him a shot under the skin to give him some extra fluids as well. Ugh, I hate him being in distress and I have a feeling he is okay but I just dont know what to do.

My sons puppy 10 week old lab got into some coconumt sweet bread with raison's. My son knew she got into the trash yesterday but didn't see her eating anything. This morning she went out to pee and a few hours later she started throwing up a lot. The throw up was long shaped like the bread with some pink (the color of the bread) with raison's and I realized it was the mexican sweet bread that she ate. I am out of the area and unable to take her to the vet.

My dog Coco, a 75 pound boxer, ate four grapes. This was about 10 hours ago and she seems fine. She did pee once and then tried again but nothing came out, which she had been doing for a couple weeks now. She is still eating and her stomach seems fine. We can’t take her to the vet and I’m just really scared and don’t know what to do. Is four enough to harm her even though she weighs that much?
