My dog ate an onion ring. Is emergency vet needed for onion poisoning?

Oh no, that was naughty of Piper! If she just got into the trash within the past two hours, you can take her into a vet immediately to have vomiting induced to get the onions out of her system to prevent any toxicity from occurring. Otherwise, you can monitor her for now. There likely isn't enough onion in these rings to cause toxic symptoms, but to be safe if you see any lethargy, weakness, ataxia, pale gums, hyper salivation, vomiting, diarrhea, or bloody urine, I would have Piper seen by a vet immediately.

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!

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.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. In order to get a toxic amount of onions, a normal sized Jack Russel Terrier would have to have eaten about a whole onion. If it was just a few pieces I wouldn't be too concerned, however if it was a large amount I would have her seen by a vet for a blood test to see if her red cells are affected. Otherwise, I would watch her for vomiting and diarrhea, as mold from old food contains toxins that can cause severe gastritis, as well as tremors and seizures. If you are unsure of how much she had, I would have her seen by a vet for a blood test. If you look at her gums and they look brown instead of pink, or she has any trouble breathing or is weak and lethargic, then this is very very serious and you have to get her to a vet right away. Best of luck with your little girl.

If Bo only ate a handful, there likely won't be enough onions in them to cause any problems. Since he is acting normally, I'd just keep an eye on him for now, but my guess would be he likely will be ok. Best of luck.

Oh no! Poor Waffle! Decreased energy, pale gums (due to anemia), increased heart rate/breathing rate, vomiting, and a reduced appetite are all signs of potential onion toxicity. See the link below for the pet poison helpline to get more information on onion toxicity: https://www.petpoisonhelpline.com/pet-safety-tips/are-onions-poisons-to-dogs/ I recommend you call them immediately, as they may recommend immediate veterinary treatment for Waffle based on the amount of onion she ingested, her small size, and the fact that she has been vomiting. Good luck, and I hope she feels better soon!
