My 100-pound dog ate fried onion petals. Should I be worried?

While onions can be bad for dogs that is not likely enough to cause any toxicity problems. However I would be worried about it being fried and causing an upset stomach and pancreatitis. This can be painful and start with a decreased appetite, vomiting, diarrhea and lethargy. If you notice any of these symptoms, take him to the vet for testing and treatments.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Onion in toxic to dogs but it does not sound that Dakota has eaten large enough amount of onions to develop intoxication. The toxic dose of onion is about 15-20g/kg of bodyweight, so it means that Dakota would have to eat about 300-400 grams of onion (which is a whole large onion) to get into trouble. Please, keep an eye on her at home, she may develop mild signs of gastroenteritis (one vomit, mild diarrhea etc) but there should not be any other worrying symptoms.

Thank you for reaching out to Petco Pet Education Center, formerly Petcoach with your question about GG. The toxic amount of onion in dogs is 100 grams (about the size of a medium onion) per 20kg of a dog's weight to cause toxic effects, which means that a 45 pound dog would have to eat a medium to large onion to experience dangerous toxicity levels. Luckily in this case, two onion rings will not contain that much onion. There is a concern about the fattiness of the onion rings, as they are fried, and fried and fatty foods can cause pancreatitis in dogs. I would monitor her for vomiting, diarrhea, abdominal pain, a hunched up appearance, vomiting undigested food, and lethargy. If you see any of those signs, have her seen by a vet immediately. Hopefully, however, she will be just fine, and I don't think in this case, you need to do anything. Don't induce vomiting, and there's no need to take her into a vet unless you see any of the signs I just mentioned. I hope this helps!

It typically takes ingestion of about 0.5% of your pet's body weight of onion to be at risk of onion related toxicity. This calculates out to be approximately 0.15 lbs, or around 2 ounces. Unless your pet ate anything close to that amount or more, it is not recommended to do decontamination for him. With a piece of [onion](https://www.petcoach.co/canigive/dog/onions) that only weighs a few grams I would not be concerned. Just monitor him for the next couple of days for any GI upset, lethargy, panting or pale gums. And if he gets a hold of any more you can always contact the [Pet Poison Helpline](https://www.petpoisonhelpline.com/). There is a charge associated with this call.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. Onion in toxic to dogs but the toxic dose is fairly high. Sadie would have to eat more than a half of a large onion (or a whole normal size onion) to get into any trouble. She may show mild signs of stomach upset, like a bout of vomit or loose stools but there should not be any more concerning symptoms.

You are correct in that onions (and garlic) are toxic to dogs. The good news for Glock is that the degree of toxicity is related to his weight and the amount of onion he consumed. Average onions weigh anywhere between 70-150 grams and can pose toxicity concerns if 15 grams of onion per kilogram of body weight are consumed. Glock would need to ingest around 545 grams of onion to cause the red blood cell concerns associated with onion toxicity. Long story short, you don’t need to do anything or worry!

It is unlikely that there was enough onion present to cause a problem, but eating that much pizza will likely cause some gastroenteritis (inflammation of the stomach and intestines) which could lead to vomiting and diarrhea. He could also develop pancreatitis. If he starts vomiting, having diarrhea, isn't wanting to eat, or seems lethargic, please take him to your vet for treatment. In the meantime, withhold for at least 12 hours, then offer small amounts of. a bland diet such as boiled chicken and white rice for the next couple of days. Onions will cause oxidative damage to the red blood cells which can result in anemia. If the onions are going to be an issue, it will be a few days before you would see this, and generally would present as decreased appetite and lethargy. If those symptoms are noted, get him in to your vet for bloodwork. Again, I doubt there was enough onion present to be a problem. as generally its a relatively large amount that has to be ingested to cause a clinical problem. thanks for asking Petco Pet Education Center, formerly Petcoach!
