What is Raisin 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 Raisin 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 Raisin 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 Raisin 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 Raisin 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.

Hello the toxic dosage of raisins is unknown. Someone just one causes issues while some can get a whole box with no issues. It would be best to see your vet. They can start treatment right away.

My dog ate a small piece of a oatmeal raisin cookie. It was by accident and I dont believe he had a raisin chunk in the cookie but im still concerned. He seems fine but it's been only a couple of minutes and he only just seems a little thirsty.

Hello raises can damage your dogs kidneys. Usually IV fluids are given to help flush any toxins out of their system. If they are not eating, vomiting or acting lethargic they need to be seen right away. Your vet can run bloodwork to see if this did any damage to their internal organs

My 2 yr old pitsky (50lbs) and 2 yr old great golden labmariner with dwarfism (45lbs) both got into a small amount of bred pudding I had on the counter ( roughly 4 bites left) just now. I know raisins can be fatal. Should I take them to an emergency vet? It just happened so they're behaving perfectly fine right now.

Hello Raisins are definitely toxic to dogs. Without know which dog ate how much, I recommend that you take to a veterinarian so they can be made to vomit (as soon as possible). Raisins can be damaging to the kidneys, depending on the amount consumed. Good luck.

Thank you for your question. By now, I would imagine that you will know if your dog is okay or not. They may or may not have needed Veterinary attention for GI upset or kidney disease. I hope that all is okay with your dog.

My dog accidentally ate a raisin and about a few hour later he started pooping a lot. It wasn't diarrhea but it was not completely solid. His stomach seems to be slightly bloated too. I'm not sure if I should take him to the vet

Some dogs will have a reaction to raisins that can cause kidney failure, and it would be best to have your dog seen by a veterinarian. They may want to run some lab work to assess kidney function, and see what they need to do from there.

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?
