What is Onions Poisoning?

Allium species, including onions, garlic, leeks, and chives are toxic to dogs. Plants in this family contain organosulfur compounds which account for the distinctive odor and flavor associated with them. These compounds are metabolized into highly reactive oxidants which can damage the red blood cells (erythrocytes) of dogs, particularly certain Japanese breeds like Akitas and Shiba Inus. The oxidants bind directly to the erythrocytes, so these breeds are particularly at risk because of the specific chemical make-up of their red blood cells. All dogs are susceptible however, in contrast to humans whose red blood cells aren’t affected by the organosulfoxides. As the oxidant level within erythrocytes become higher than the cells’ antioxidant metabolism capacity, a condition called oxidative hemolysis results which affects oxygen transport and causes red blood cells to rupture and be destroyed. The erythrocytes will be marked by Heinz body formation, an abnormal blood cell visible upon microscopic examination of a blood smear.

Dogs with allium species toxicosis will develop hemolytic anemia. Typically the onset is delayed by several days, but large doses may cause symptoms of anemia as little as one day after ingestion. Vomiting, diarrhea and gastric upset may also be present. The toxic dose is typically 15-30 grams per kilogram of the dog’s weight, or about .5% of the body weight. All types of allium species can cause this toxicity, but garlic is the most concentrated and therefore the most dangerous for dogs. Dried, powdered, and cooked products are just as toxic as those that are fresh and raw. As the condition progresses, the bone marrow will generate new red blood cells and the anemia will pass, as long as no further exposure takes place. High doses will need to be treated with a blood transfusion to avoid fatally low levels of erythrocytes.

Onions, garlic and other members of the allium family are toxic to dogs. This is called allium species toxicosis, or onion toxicity. Symptoms may take several days to manifest.

Symptoms of Onions Poisoning in Dogs

These symptoms could indicate your dog has eaten onions or garlic.

  • Smell of onions or garlic on the breath
  • Excessive salivation
  • Irritation of the mouth
  • Vomiting
  • Diarrhea
  • Lethargy
  • Signs of abdominal pain
  • Rapid heartrate (tachycardia)
  • Panting (tachypnea)
  • Weakness
  • Exercise intolerance
  • Collapse
  • Pale or bluish gums

Types

These are the types of products you should keep away from your dog.

  • Garlic – most toxic, about five times as potent as onions
  • Onions
  • Leeks
  • Chives
  • Scallions or green onions
  • Garlic or onion powder

Causes of Onions Poisoning in Dogs

These are some of the causes and risk factors associated with allium species toxicity.

  • Ingestion of fresh growing onions, garlic or chives
  • Feeding food prepared for humans to a dog
  • Dog chews open a container of dried or powdered onions or garlic
  • Certain breeds are more susceptible (Japanese breeds like Akita and Shiba Inu)
  • Some factors can make the red blood cells weaker and increase a dog’s susceptibility to allium species toxicosis (Zinc deficiency, glucose-6-phosphate dehydrogenase which is an inherited deficiency, and some drug treatments

Diagnosis of Onions Poisoning in Dogs

If you know your dog has ingested a product that contains onions or garlic this will make diagnosis easier. If the dog is already showing symptoms of lethargy and weakness, a low red blood cell count (hemolytic anemia) will be visible on a blood test. This can also help to indicate the severity of the problem. Urinalysis will show high levels of hemoglobin in the urine. Heinz body anemia may be visible on a blood smear examination even before there is a marked drop in red blood cells. Other symptoms, like a smell of onions or garlic on the breath (with recent ingestion), or vomiting and diarrhea with undigested pieces may also be an early indication that your dog has allium species toxicosis. For unknown instances of poisoning, the veterinarian may ask what foods you regularly give your dog and suggest you check the list of ingredients.

Treatment of Onions Poisoning in Dogs

If the poisoning is still recent, vomiting may be induced and the dog will be given activated charcoal to reduce absorption in the gastrointestinal tract. The veterinarian will tell you to monitor your dog for signs of anemia over the next few days and may recommend a diet low in oxidants. If a large amount has been ingested, your dog will need to be kept in a veterinary hospital for that time period. Severely ill dogs will need supplemental oxygen to make up for the reduced circulation of red blood cells and a blood transfusion could be necessary to stabilize your dog until the bone marrow is able to generate enough new, healthy erythrocytes.

Recovery of Onions Poisoning in Dogs

Dogs will recover from mild exposure to onions or garlic however severe poisoning can be fatal, especially without treatment. If you know you dog has eaten onions or garlic, you should take him to the veterinarian immediately even if there are no immediate symptoms. 

Avoiding exposure is the best way of managing the condition. If you are feeding your dog any food prepared for humans, check the list of ingredients for onions, garlic or other allium products. Even if your dog remains asymptomatic, continual low level doses will make any accidental ingestion much more serious. Put any spoiled food that contains onion or garlic products through a garbage disposal or place in a sealed trashcan. Take precautions if there are allium species growing in your garden. Dogs don’t normally like the taste of these plants, but it’s safer to keep them out of reach.

I do not see any

Hi , I have a year old GSD, and have been feeding her high quality kibble 2X a day. She mostly will not eat the kibble as it is. I sometimes add cooked eggs, other times I've been adding about 1/4 cup salt free chicken broth. I just learned about how toxic onions can be! This has gone on for about two weeks. She looks great and shows not signs of any reaction reaction. Her gums look pink. But I cannot tell if they are pale. Thank you.

I'm not sure from your description where the onions are that you are worried about, or how much or how frequently she is eating them, but onions can be toxic to the bone marrow if fed over time. If you aren't sure that Annie is okay, a simple lab test can be run by your veterinarian to test her red blood cell levels. In the meantime, it would be best to stop feeding her onions, as they are not good for her.

I fed my miniature poodle about 5-6 pieces General Tso's Chicken which had quite a bit of sauce on it, but no pieces of onion. It is a spicy dish cooked with onions and red and green bell peppers. She has been restless most of the night and got up once and drank water. She is resting now. She weighs 12 pounds. What do I need to look for?

Dr. Michele King, DVM
Dr. Michele King, DVM

I would suspect the spiciness and the sauce are probably causing some stomach upset for Belle, more than any risk of toxicity. If she develops diarrhea, vomiting, lethargy, or a decreased appetite, it would be best to have her seen by her veterinarian. Dogs don't tolerate fat and spice the way that people do, and those foods are probably best avoided for her.

Thank you so much, Dr. King! Wag is such a great service, and I do thank you. Belle is her normal self today. This experience has made me much more aware of feeding her people food, and I will take your advice. Think I'll just give her a plain chicken breast when I want to give her a treat.

That is a lot of onion for Dozer to eat, and he may show signs such as vomiting, diarrhea, weakness, lethargy, of loss of appetite. If he shows any of those signs, he should be seen right away to be assessed and have lab work done to make sure that he is okay. That one time dosage isn't necessarily enough to be toxic, but you need to keep a very close eye on him.

Powdered forms of onion and garlic are more potent than fresh and many powders have added salt which is also concerning, both onion and garlic poisoning cause haemolytic anaemia but it is difficult to know how much exactly was consumed. Symptoms of poisoning normally take a few days with pale gums and lethargy being the main symptoms, you should visit your Veterinarian to be on the safe side and you should monitor gum colour as well.

I have an almost 2 year old 70 lb. German Shepherd. We planted a garden on Sunday (that we are struggling to keep her out of!)

Onions can be irritating to the GI tract, and cause vomiting and diarrhea, but they can have longer term effects on the blood system, and it is important that she not eat them. It might be a good idea to have your veterinarian look at her and check a blood sample to assess whether she is having any problems so that she can be monitored. Any signs of lethargy, inappetance, vomiting or diarrhea would mean she needs to be seen right away. I hope that you are able to keep her out of the onions in the future!

The amount of onions and garlic in the sauce was likely not a toxic dosage for Onyx, given her size, and she is more likely suffering the effects of eating things that she should not. Charcoal will not be helpful for her at this point, and if she continues to vomit or have diarrhea, it would be best to have her seen by her veterinarian. I hope that she is okay.

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM

For a 50lb dog, this shouldn’t be a big problem but all dogs react a little differently; the problem with onions (and garlic) is that they cause the destruction of red blood cells so looking out for pale gums, increase in respiration and lethargy are normally key signs of poisoning. Keep a close eye on her and if the consumption was within a few hours the administration of activated charcoal can help, but any concerns or symptoms you should visit your Veterinarian immediately.

Thank you for your email. Garlic and onion toxicities tend to build over time, with either a large amount al at once, or small amounts frequently. The small amount that Harper ate shouldn't cause any problems, but you should monitor her for any signs of vomiting, diarrhea, lethargy, or decreased appetite and have her seen by her veterinarian if any of those signs occur. I hope that all goes well with her.

Thank you for your email. Onions and garlic can both cause problems with bone marrow production and red blood cell destruction. They tend to be more chronic toxins, unless a large quantity is eaten all at once. With the amount that she ate, I would be more concerned with GI effects - vomiting, diarrhea, lethargy, or lack of appetite. If she seems lethargic or doesn't want to eat dinner today, or continues to show any other GI signs, she should be seen by your veterinarian, and they can take a blood sample to make sure that she is okay. I hope that everything goes well with her.

He goes to the bathroom more then usual, not sure if he is actually going or just trying to go. He breaths hard like he has a stuffed up nose. He seems to be hungry all the time. He gets mainly wet dog food twice per day and not that much in each feeding. Maybe twice a week he gets table food instead of dog food as a treat. Unfortunately there are onions/garlic in it. I just read about these things being bad. His gums look okay. Could these be signs of onion poisoning.

Thank you for your email. Long term onion toxicity can cause bone marrow problems, so it is best if Petey doesn't eat those things. As far as what is going on with him right now, it would be best to have him examined, as your veterinarian can assess him, recommend any testing necessary, and try to resolve his variable signs that are going on.

My holistic vet included scallions on the list for her homemade diet. The diet ratio is 50% meat, 25% oats, brown rice/root plants (she gets sweet potatoes) and 25% veggies/fruits (usually pineapple, blueberries in season, green apple [minus seeds], spinach, romaine, asparagus). Earlier in December I added about 4 - 8 ounces chopped scallions in the last couple of batches that I made for her. (Each batch equals 10 pounds of food and lasts at least 10 days). So if my math is correct she ate .4 - .8 grams of scallions each day but over a two week period. My 6 y.o. Basenji/Lab has always had off/on again diarrhea that is managed with raw goat milk, sweet potoato and minimizing stress. I don't recall any diarrhea during that period. But she may have vomited yellow bile once or twice over that time. No lethargy or anything. I didn't know to check her gums. My question is should I still take her in to get blood work if she has no symptoms now that it has been a couple of weeks since she ate the scallions? Can the toxicity resolve itself in the body? Thanks.

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM
2484 Recommendations
Scallions, like onions and garlic, cause anaemia by destruction of the red blood cells; treatment for this type of poisoning is supportive and symptomatic whilst the body sorts itself out, severe cases of poisoning may require blood transfusion. If it has been a couple of weeks since Luna last consumed scallions I wouldn’t be too concerned especially if gums colour is good and there is no change in activity levels. Just keep a close eye on things and double check all ingredients with a Google search checking reputable websites like ours (Wag!), ASPCA and Pet Poison Helpline. Regards Dr Callum Turner DVM

Thank you for contacting us about Daisy. Onion toxicity in dogs tends to occur over a chronic timeline, rather than an acute occurrence.

Dr. Callum Turner, DVM

There is varying information on the toxicity of onion, I tend to use the information provided by dvm360 which state that: “Consumption of as little as 5 g/kg of onions in cats or 15 to 30 g/kg in dogs has resulted in clinically important hematologic changes. Onion toxicosis is consistently noted in animals that ingest more than 0.5% of their body weight in onions at one time.” For our American friends, 15-30g/kg is roughly 7-14g/lb; an eighth of a cup of raw chopped onions is around 20g or 0.7oz. Inducing vomiting is good within two hours of consumption, after that it is not really effective; you should monitor Juggernaut and visit your Veterinarian when they open.

Our 10 month old Newfoundland is a very picky eater. In order to interest him in food his vet suggested we put a little broth on his dry kibble. I do not do it for every meal but have generally added about a half cup of chicken or beef broth to his dinner for months. I was reading that onions are toxic to dogs and so checked the ingredients and there is onion powder in the broth. I immediately called the vet, but they didn't seem concerned. I of course will stop adding broth to his kibble, but should I be worried that he was exposed to the onion powder in the broth for such an extended period of time? Is there the potential for lasting effects from it, or will he be fine if he doesn't eat anymore. I am very worried and somewhat surprised the vet didn't think it was a problem.

Lethargy and loss of appetite are common symptoms of onion poisoning; the onions cause haemolytic anaemia which reduces the oxygen carrying capacity of the blood which lead to lethargy, pale gums are usually a concern in these cases. If Rufio is otherwise alright, it may just be a case of stopping to give the onion powder (garlic is five times more poisonous than onion - just to let you know for reference) and allowing Rufio to regain his strength. Without examining Rufio, I cannot tell you how serious this is, but since it is a long term case I would just allow him to get it out of his system; if his gums are pale visit your Veterinarian immediately. Regards Dr Callum Turner DVM

It's obvious that your vet isn't at all concerned for the health and well being of your furbaby. A different vet may be to Rufio's best interest.

Both onions and garlic are poisonous to dogs with garlic being five times more poisonous than onions; both cause hemolytic anaemia and decrease the oxygen carrying capacity of blood, check Otis’ gums to see if they are white if they are or you notice any symptoms listed on this page please visit your Veterinarian regardless of cost.

Onions are poisonous to dogs and garlic is five times more poisonous than onions; consumption of these ingredients (even in small amounts) causes haemolytic anaemia where red blood cells are damaged and no longer function to carry oxygen in the body. If you are noticing pale mucous membranes (gums etc…) it would be best to have Chloe checked over by her Veterinarian (with blood cell counts) to be on the safe side; if you want to give her cooked chicken, boil some separately with no seasoning.

My dog is breathing faster than normal and is acting tired. She did eat almost all her given amount (specified to weight) of dog in one sitting but it is possible that she may have eaten a very small piece of a chopped onion off a burger. Could this have caused her not feeling well?

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM

Onions cause damage to red blood cells, when the red blood cells are damaged they are unable to carry oxygen around the body which would cause a dog’s breathing rate to increase. If you are suspecting onion poisoning, it would be best to visit your Veterinarian for a check over and a blood test to be on the safe side as she is displaying these symptoms.

Depending on which source you read, a toxic dose of onion in dogs is between 15-30mg/kg (7.5-15mg/lb). If ingestion occurred within the last two or three hours, try to induce vomiting using 3% hydrogen peroxide and administer activated charcoal; if you see severe symptoms or you are concerned, visit your Veterinarian to be on the safe side.

He has since eaten some plain brown rice not sure if this is the correct thing to give him?

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM
2484 Recommendations

A dog Buster’s size would need a toxic dose of 750g of onion to put us in fear for his life. The vomiting and diarrhoea maybe in response to other ingredients in the stew like garlic (five times more toxic than onion) or some herbs. Buster is probably having a gastrointestinal reaction to the rich human which his body isn’t used to. Ensure that Buster continues to drink plenty of fluids and feed him a bland diet of boiled chicken and rice. Check Buster regularly for blood in his stool or vomit, signs of abdominal pain, pale or bluish gums, increased heart rate or increased respiratory rate; if he is showing any of those symptoms visit your Veterinarian or Emergency Veterinarian immediately.

An eighth of a cup of onions isn’t a large amount for a dog weighing 38lb, but each case is different; since she has pale gums, it may be worth visiting your Veterinarian anyway just for a check over as pale gums may be attributable to other types of anemia (not caused by onions). Regards Dr Callum Turner DVM

My dog who is a golden retriever ate maybe 6 grams of onions. It's been about 7 hours now ( didn't know they were toxic) and she's about 70 lbs. her gums are still pink, and she's eating normally, drinking and using the bathroom , acting completely fine and she's playing with her toys. Should I still be concerned for what is to come the next few days? I just have been reading so many different pages and I just want to know if she's going to be okay for that amount of onions. They were cooked/ boiled. Don't know if that makes any difference

My dog is a five and a half month 41.6 lbs. pitbull huskey mix. He got into my lunch yesterday and ate all of it. My lunch consisted of white rice, grilled chicken, zucchini, carrots and onions. I used half a large onion and then split it into three containers (one of which is the one he ate). He also got into his treats and ate about 6 milky bones and about a full bag of Bil-Jac PBnanas treats. He does not seem lethargic and does not have vomiting. His gums look slightly pale but still pink and his stool is runny but not quite diarrhea yet. Should I be worried? He has been very active, we walked 45 minutes yesterday and today and still had energy to play when we got home. He is eating and drinking fine and his pee is a normal color.

It sounds like Ares had quite the buffet yesterday, I do not believe that Ares consumed enough onion to be significant to cause a poisoning event; it would be best to keep an eye on him and to monitor his diarrhoea, the diarrhoea is most probably caused by him eating food which is gastrointestinal tract is not accustomed to. Ensure he remains hydrated and that his gum colour doesn’t go more pale; if you notice lethargy or any other worrying symptoms visit your Veterinarian. Regards Dr Callum Turner DVM

Onion poisoning usually occurs when a larger quantity of onion is consumed; the diarrhoea is probably due to some gastrointestinal irritation caused by the potato and onion (as well as any seasoning that was present). Just keep an eye on Nymeria for a few days; you could try to give some plain canned pumpkin to try to firm up the stool. If the diarrhoea continues, visit your Veterinarian.

I'm not sure if my puppies ate any onion but its possible they may have gotten some. We try to limit the people food they get but they are very naughty and still get into the kitchen. We do try to make sure all the poisonous food goes into the trash. But a few hours ago one started vomiting and now at least 2 have started as well. Could they be dealing with stomach upset from the amount of people food they had yesterday or could this be a sign of onion poisoning?

Human food should be eliminated from their diet as not only onion but garlic (five times more poisonous), herbs, spices and numerous other food can be toxic to dogs; better stay on the safe side. If you are noticing that some of your puppies are vomiting, it may be due to onions, other food ingested, other poisoning, parasites, infections etc… If you notice them eat anything in the future, 3% hydrogen peroxide to induce vomiting followed by activated charcoal is best for all poisonous food to dogs. If you are suspecting onion poisoning, visit your Veterinarian for supportive care or if you suspect a tummy bug, keep them hydrated and keep an eye on them. I cannot say the cause without examining them and looking at their vomit. Regards Dr Callum Turner DVM

Hello. I found out today that not just onions are toxic to dogs, but any foods that may have been cooked with them as well. Because of the holidays, over the past week I've fed my 80 pound lab a few nibbles of beef/chicken that have been cooked with onions/garlic. I'm having trouble finding definitive information on what is considered a cumulative toxic amount over many days. He is acting relatively normal, but this morning's stool was encased in a layer of mucus (like a sausage casing) & this afternoon he had one bout of diarrhea. He also seems to be sleepier, & his third eyelids both seem irritated/red, although he does have mild allergies. He is otherwise coherent- playing, eating & drinking normally & his urine is still yellow. Gums are responsive. Do I have reason to be worried?

Dr. Callum Turner, DVM
Dr. Callum Turner, DVM
2484 Recommendations

Generally between 15-30g/kg of onion is considered a toxic amount; so a 36kg (80lb) Labrador Retriever would need to consume 500g to 1kg of onions (1-2lb); garlic however is more potent than onion being five times more dangerous to dogs. However little amounts that Charlie has consumed, I would recommend a visit to your Veterinarian to check Charlie over and to have a blood count since onions and garlic cause destruction to red blood cells which are vital to carry oxygen around the body and to carry carbon dioxide out (towards the lungs). Symptoms of onion and garlic poisoning include lethargy, vomiting, diarrhoea, abdominal pain, pale gums, excessive salivation, increased heart rate, increase respiratory rate, jaundice and seizures.
