There are many kinds of food that humans eat which are unsafe for dogs. Onions are not an exception. Feeding your pooch onions can make him seriously ill, whether they are raw, cooked, or in powdered form.
What you Need to Know
Onions are toxic to canines because of the substance they contain known as thiosulfate. Since dogs do not have the enzyme used to digest this substance, onions become a harmful food for them. Although rarely any observable side effects can be seen if your pooch consumes just a minimal amount of onions. For example, he sneaks a piece of pizza off the counter or steals a bite of your burger, most likely he will be just fine. Too frequent feeding of onions, however, can affect your pet’s health and vitality. Additionally, onions contain a compound called organosulfur that results in toxicosi, a condition brought about by poisoning which can be easily absorbed by the dog’s digestive tract.
Onion ingestion commonly leads to liver damage, asthmatic attacks, allergic reactions, weakness, diarrhea, discolored urine, anemia, vomiting, and even dermatitis.
Onions and Heinz Body Anemia
One of the most critical problems that arises from onion toxicity is canine Heinz Body Anemia, also referred to as Hemolytic anemia. It is a condition that is brought about by the destruction of the dog’s red blood cells that leads to a decrease in red blood cell count; thus, causing anemia. “Based on research, a single oral dose of dehydrated onions led to a large number of Heinz bodies within erythrocytes within 24 hours, with the maximum amount occurring up until day 3 until a decline was measured,” reports Animal Answer Guide, a site that answers common questions about dogs and other animals.
Symptoms vary depending on the amount of onions the dog has consumed, his size, and the time period for which they have been ingested. It is notable that consuming a large amount of onion in a single sitting is less dangerous that consuming a very small amount over a length of time. Remember this if you’re someone that feeds your dog from the table. Many of the foods we eat contain at least a small amount of onion or onion powder. Read your labels carefully and avoid feeding these foods to your dog.
Common warning signs for Heinz Body Anemia include pale mucous membranes like the gums, brownish or reddish urine color, rapid heart and/or respiratory rate, weakness, and depression. Vomiting, diarrhea, and loss of appetite may also be observed.
What to Do when Your Dog Ingests Onions
It is important that you immediately consult your vet if symptoms occur as a result of onion ingestion. Treatment normally involves inducement of vomiting, carrying out gastric lavage or flushing out the stomach, and making use of activated charcoal to treat not just poisoning but allergic reactions as well. Bathing and drying your dog may also be necessary in cases of skin infection.
Other treatment options include maintaining the dog’s hydration by providing fluid in his bloodstream, applying therapy for liver damage, and calling for blood transfusions if necessary.
Did you know that there are many over-the-counter human medications that can be safe and effective for dogs, when used correctly?

reading the above posts, i have a comment to make. We’ve had 3-4 dogs as pets always since i was born. I am 45 now. My mum uses onion water for therapy on all our pets and they’ve recovered out of serious stomach problems including gastro. Procedure : Take one whole onion , make a paste out of that in a blender and add water about 300ml to make it a thick fluidy liquid. Collect all in a seperate vessel and boil content for max 2 -3 mins after reaching the boiling point . Let the whole broth cool down until it reaches ambient temp. Strain water only using a net/tea leaf strainer. the onion water tastes sweet but has an odd smell which pets would reject (humans can have as in in a cup). We use a syringe collect 25-50ml per dose and force feed our pets orally. This has been very effective and relieves them with severe gut problems. Continue the therapy 3-4 times for a day or two. The first dose will work instantly and my pets have responded from not eating at all to finishing some vanilla ice cream, slowly returning back to their original home cooked food diet Having said that, i must tell we dont feed our dogs onions daily, but yes for therapeutic reasons only.

What is not spelled out in the article is that the illness (hemolytic anemia) caused by eating onions may take SEVERAL DAYS to develop, so your dog can seem to be healthy in the meanwhile. Obviously if you KNOW it just happened, make the dog vomit, and/or if it has been several hours, feed activated charcoal (make water slurry by mixing 4:1 with liver powder) to reduce the amount of onion absorbed in the GI tract. Take your dog to the vet who will provide supportive care as there is no antidote. Red/brown urine and tarry stools are signs the illness is progressing. Home care to prevent oxidative stress should include Vitamin C and NAC every 8 hours, Vitamin E 1x/day, and Milk Thistle 2x/day for liver support (dosages weight-based – ask your vet).

Omg, I’m freaking out right now. My dogs had a small bit of soup that had cooked leeks in it 24 hours ago. But from everything I’m reading it could take days before they show signs of it harming them. It’s 3 in the morning. I’m freaking out.

Well my dog has been truly lethargic since I shared my chilli with him. He’s had vomited up the chilli which caused me to realize I didn’t get all of them out. How negligent and unloving on my account! I given him fluids but he has barely done any rebounding. What can I do?

We rescued a two year old Boston Terrier . Last night he got into the garbage and set some raw onions. We discovered it about three hours after he had eaten it. While it was a small amount ( he weighs 35 pounds) He started to cry and seemed lethargic. Once we discovered what he had done. We gave him soda crackers and skim milk string cheese. We watched him when he went outside.. stayed up with him
He starred to act normal about an hour after he ate the crackers and cheese.. this morning he seemed back to normal. We will watch him very carefully and if any symptoms appear we will take him to the Vet..
It seems giving him the crackers and cheese seemed to help him..

So my dog has ate onions since day one, she loves them…
But now i know they are bad for her…
So i haven't fed her onions in a week now and i will not give them to her anymore.
should i do anything? or is she safe now?
Brandy Arnold
Oct 20, 2017 at 9:37 am
There are a lot of factors to consider to determine if anything should be done for your dog… How old is she, and how many years has she been eating onions? Has she eaten them daily? Is she exhibiting any symptoms mentioned in the article? Long-term eating of onions can lead to chronic health problems that would be be treated if caught early, so visiting your veterinarian for bloodwork to test liver function would be a great idea.

For everyone freaking out about their dogs eating a few onion rings or a little bit of onion, its all based on how much your dog ate and how heavy your dog is. Your dog has to eat a certain amount of onion per pound of body weight before onion toxicity kicks in. So someone earlier was right, this article is a scare tactic, filled with half truths. My source for this information is my vet.

I fed my neighbors tiny dog two small bites of hamburger cooked in onions.It been 2 weeks and i just found out the dog has been throwing up and the dog stools are black tar.its 16 years old and my neighboe says its her age .I hope her dog isnt sick because of me?
William Henriques
May 23, 2017 at 8:28 pm
It is highly unlikely that the small amount of onion that you fed the dog would cause much of a reaction. The age of the dog is the biggest thing to think about because it will be more sensitive to the effects of anything ingestible. I'm sure you're not the only one that fed the dog treats. I hope the dog is doing better now.

1/2 cup milk 2 Table spoons Hydrogen Peroxide….let them drink about half of it.
My Greyhound just ate 1/2 a cooked medium sized onion left on the counter from chicken soup. (that's half the size of your fist) Thanks to this thread, I used 1/2 cup of milk and 2 Tbs of Hydrogen Peroxide…she drank 1/3 and it induced vomiting within 2 minutes. Went trough 10 catch-bowels but the onion came up -ALL of it. Less than 20 minutes.
There was some digestional irritation for a few hours but it worked!!!
Thank You.

Hi Ricia. Your dog not wanting to eat, vomiting and having diarrhea is a terrible sign. First off you should’ve called your vet and taken her in to make the vet make her throw up. If she threw up on her own, is weak, doesn’t want to eat and has diarrhea means that it is affecting her liver and kidneys . That means if the onions is fully digested without getting out of her system she could have kidney failure which could cause even more trips and money to the vet to cure her and find a solution. And possibly surgery. What I would recommend you to do right now is take her to the vet and the veterinarian will do some blood work and based on the results you get back they will find a cure. Hopefully she gets better. Sorry for the late reply.

PATTI

Grass is normal though the dog may still vomit some up.
Onions are a big issue. My little dog has discovered how to get up onto the kitchen counter. If salad bowls with salad residue are left unattended, he will try to lick them off. It cost me $1,000.00 the one and only time he got into the salad bowls. I think I have got to start eating food with out any onion to help him stay safe.

I just wanted to add that garlic, onions, leeks and green onions are all toxic to dogs and cats. So watch those relish platters and all holiday food out of the mouths of all animals. Also remember grapes and chocolate will poison them too! It’s safer to put your pets in a closed room with food and water and maybe leave a TV or radio so they aren’t listening in to every detail going on in the rest of the house. It is too difficult to keep your eyes on your guests, food and pets at the same time. Make this a safe holiday!

Onions and garlic do the same thing. Even in tiny amounts, they cause red blood cell lysis aka hemolysis aka hemolytic anemia if they get either a lot at one time or a little bit frequently. I know there is question of if garlic is bad but the fact is, they cause lysis of red blood cells and it takes awhile for spleen to make more. Period. Why would you take the chance? Ok I don’t want to argue about that. My little Maltese got two of my 1000 mg garlic gel caps Thursday. Today is Tuesday. So my ten pounder ate 2000 mg of this. I gave one tsp aka 4-5 ml of hydrogen peroxide 3 percent via syringe. Then I repeated after 15 minutes. She vomited twice but I couldn’t see gel cap but it probably dissolved in four minutes because that’s what happened in my mouth. Later I read one half tsp per ten pounds but maximum of three tsp for large dog. You may repeat one time as hydrogen peroxide has toxic problems on it’s own. Called vet next morning, watch dog. She was fine till this am, tired with vomiting. Read up on this and learn from my stupidity. It may take days to see effects.

Hydrogen peroxide is a poison do not give it to animals. Not sure where this came from but I suspect it's to induce vomiting. There are other safer alternatives to hydrogen peroxide to make a dog throw up.

The animal poison hotline told me to use hydrogen peroxide to induce vomiting when my dog got into a pill bottle (knocked off table and chewed the bottle till the cap fell off!!)

Its pathetic that no one on here told these people the quick and sure solution. IF YOUR DOG EATS ANYTHING TOXIC, MIX MILK AND ABOUT A CUP [ for a 60 pound dog] OF HYDROGEN PEROXIDE AND GIVE IT TO YOUR DOG. You have about 45 minutes to do this. You should do it right away though.
This is the solution.
LIVE BY IT.

YES Michael! Thanks for posting this! I knew this, but it’s been a while since I had to do it. My dog ate cooked onion I threw out of the crock pot. I went online as a reminder and saw this. I gave him the 3 percent hydrogen peroxide(the normal hydrogen peroxide kept for cuts, etc. A reminder for people NOT to use stronger-the kind for hair colouring! This can cause damage). But, gave him about 8 teaspoons as he is around 80 lbs. I recall it is recommended approx. 1 teaspoon per 10 pounds. Walked him around calmly on a leash. He just threw up the onion after about 20 minutes. It looks like it all came up! This is a life saver! Thanks again for posting on here!!!

This is insane. Do not drink oxidizing agents. Even 3% hydrogen peroxide is dangerous. If doctors no longer recommend putting it externally on a cut, then why would you consider DRINKING it? Of course it’ll make you throw up, it’s oxidizing your stomach lining.
John
May 24, 2017 at 6:10 am
THIS IS INSANE! Do NOT give your dog HYDROGEN PEROXIDE, unless you are trying to poison it. The hydrogen peroxide would be worse than the onion. Call your vet, ask the professional. Don't believe some nut job online.

We have a Jack Russell Terrier that we have had since she was a year old. She is 11 years old now. She is my wife’s service animal (seizure response dog). I have fed her table food for as long as we have had her, she eats what ever I do. I love my onion and garlic so she has had quit a bit of it as long as we have had her. We would never do anything to harm her but didn’t know about the onion thing until this year. I try not to give her any actual onion pieces now but I still use onion to season with and she does get an occasional piece in some foods. She weighs 14 pounds and has never had any medical problems. She’s a active as any 11 year old if not more and has never had ant medical problems. I’m beginning to think all this is a big scare tactic or a way to make money for vets.

Jul 19, 2015 at 1:14 pm
Right, Charles; and many people smoked cigarettes while pouring gasoline out of a can, and never set themselves on fire. Others weren’t so lucky, and were severely, even fatally, burned.
Some years back, it was found that onion powder in meat baby foods (fed to infirm cats while they were under vet care) was found to cause hemolytic anemia. (Major baby food brands don’t use onion powder anymore.)
But if you think it’s “a big scare tactic or a way to make money for vets,” just go on doing whatever you think is right for your dog. You probably won’t post back here if some day you find out the hard way that you were wrong. It’s too bad the faithful dog would have to suffer because you think you know more than veterinarians do.

My three year old Chihuahua came down sick on Thurs night after super. Took her to Vets on Fri they said her heart was good and no temp. I told them she wasn’t eating and acting completely out of character. He gave me a tube of stuff to stimulate appetite . She won’t walk on her own, she wants to be picked up to go pee, then she stands there till you pick her back up. She hasn’t played in all these days, which is quite alarming as she is so active and playful. She wouldn’t eat her treats. Yesterday we hand fed her a little plain white turkey. She ate it. She acts like she has had a stroke. She’s confused, walks side ways .fireworks went off on the night we gave her a little part of meatball, which had onions and little garlic. We thought it was the fireworks because she really is petrified of the noise. Please advise me what to do, she just sleeps. It’s been three and a half days. Two vet visits later. Help please.

Never give dogs turkey. It nearly killed my mothers 2 dogs last year on Thanksgiving. The smaller dogs are more at risk. Please do your research on turkey. The ingredient that makes us sleepy is toxic to dogs. It cost my mother almost $1500 and a week of IV fluids to save he 2 pups.

I too have had a dog that did the side walking we later found out she was toxic, the toxicity was due to a condition called hepatic encephalopathy or liver shunt and we were giving her human food which we no longer do because basically with liver shunt every time she eats she is protein poisoning herself she has also had seizures due to this condition. I would definitely quit giving my dog people food maybe try giving her a low protein canned food like merrick vegetable medley has 9 percent protein it’s a food for senior dogs so it is highly digestible. Do you know if the meatballs contained sage and if so she needs vet care immediately. No people food and if she doesn’t eat don’t force her…my dog now does a 12 hour fast every night last meal time 9 pm next meal 9 am and for treats I open a can of dog food role it into balls or cookies and bake at 350 degrees until browned pull them out let them cool and refrigerate. Last time we fed her our food cost us about 3000.00 dollars to save her so lesson learned…absolutely no turkey and old mother Hubbard makes some bone treats called char tar bones I always have those on hand

My dog, about 40lbs or so, ate some onions on a chicken taco… she got very very sick later that night… she was whining all night in pain. We took her to the doctor and they said nothing was wrong. As I was researching what could make a dog sick, I saw onions were toxic and remembered about the taco I gave her. I don’t think it’s a good idea to assume a dog must eat a large amount to have toxicity. Don’t feed your dog onions.

My 10 month old maltese shizu mix ate a piece of a green onion and we gave him a little of thanksgiving dinner. after a few hours he threw up a lot and now he has been having tremors and even seizures. we have been to the vet and they have tested him ran blood work and all of the test have been negative. my wife and I am completely scared and do not know what to do. Our other dog had the same food and is showing no symptoms at all. he is just a lively as he ever is. My 10 month cannot walk and has lost all sense of balance. he will barely eat and we are scared and overwhelmed with what to do. it is suggested that he sees a neurologist to see if there is anyhing wrong with his brain. Please can anyone help us with this. We are so scared as parents and we truly miss his personality. If you read this please pray for our son his name is Zyan.

Before I knew anything about dogs I had a dog from a pup to a 16 yr 11 mo. I cooked veges every day for this dog, with a bit of meat. Because I grew lots of onions he had half of a large one every day. He also ate whole cooked chicken carcases, chop bones, indeed a cooked bone every day of his life. At Christmas time, he usually got away with a box of chocolates from someone careless enough to leave it lying around. He was a bitzer–about a spaniel size. Now, of course, I know a lot about dogs and have two. I wouldn’t DREAM of giving them all those toxic things would I?

There is no F’N worry with the onion crap! Unless your dog eats 8 whole onions he or she is fine. Think about dogs in the wild!

My dog (Jack Russell/Mini Aussie mix) has a history of autoimmune hemolytic anemia. I am mindful of what table foods he eats, however, a couple pieces of pizza were left out on the kitchen counter and he along with my other 2 JRT mixed dogs got it. I was not home at the time this happened, so I don’t know how much each dog ate. There wasn’t many onions on the pizza, but my concern is whether my dog with a history of AIHA is more predisposed to developing HA as a result of eating onions. It tore me up to see him suffer through AIHA 3 years ago, and I don’t know if I could handle seeing him go through more blood transfusions, antibiotics, and steroids. Thanks!

Hello,
I just now discovered that my 65-70lb Portuguese Water Dog ingested a small amount of onion (smaller than a pea). I have called my local veterinarian, he gave me some information on various symptoms that may come as a result of my dog eating onion. It has been about 5 hours and I have not noticed any of the mentioned signs. What is your opinion, should I still worry, is there anything that I can do to ensure that he is still healthy? I am very shaken up as my dog is still very young.
Please Help,
Robert

if your dogs gets into food and eats A LOT of it it can cause bloat which can kill a dog. Also large dogs can not play run after eating they can twist their gut and die.

my family just adopted a one year old chihuahua named April, she was acting like she was going to trow up, at bed time, but nothing came up this went on
till 2 in the morning caughing, and such every now and then. So I decided
to check and see on the internet what may cause this! Got to a list of foods
that are not good for dogs and see that garlic and onions are dangerous!
We had meatballs for dinner and she ate one, and I know it had garlic and onion
powder in it. After reading the dangers I got scared, and I am planning on sitting with her the rest of the night! Would one meatball have enough, to be concerned about!!! Please let me know.

If it was a whole meatball, maybe. It may have just upset her stomach. I have 5 Chihuahuas. smallest one is 3 pounds, largest is 8. They love meat balls, but the tiny one gets like 1/8th of a meatball and the rest get 1/4.

Our dog was diagnosed with hemolytic anemia. He had gotten into some soup which had onions in it but did not show any symptoms. Is it temporary or will he always have it?

One of the worst things a pet parent (owner) goes through is receiving the news that their dog has Hemolytic anemia. For those who have heard those words avoiding onions or being really careful with onions around our pets is no problem.
