My dog ate onions. He seems fine after 16 hours. Is he okay?

With this small amount of burger and onion mixed in, it shouldn't be a problem, especially after just 1 dose. However, it is best to monitor him for the next 24-48 hrs for any signs of vomiting, diarrhea, or decreased appetite. However, he will likely be just fine. Best wishes with your pet Bert moving forward. Take care.

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. If it was just a one time small piece, he will be fine. A dog this size would have to eat a tablespoon or so of cooked onion to even begin to have any issues. He will be fine. Thanks for using Petco Pet Education Center, formerly Petcoach.

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.

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!

It sounds like you did the right thing for Loki so far. If you ever have questions about what is safe to give him or your other pets, please feel free to ask us here on Petco Pet Education Center, formerly Petcoach! That is what we are here for. I'm sure your vet's office would not mind to answer questions if you call them either. Keep an eye on Loki for the next few days because, as you already know, onions can be very dangerous in these little guys. If you notice that Loki seems more lethargic or tired than normal, take him to your vet right away. Once there your vet can perform a lab test (a CBC) to make sure the onions did not cause a problem.

A few pieces of onion ingested by a dog of Mochi's size will likely cause nothing worse than some minor stomach upset, if anything at all. She would need to eat 2 or 3 med/large onions in order to be at risk of serious toxicity. If she develops vomiting or diarrhea but continues to behave normally, you can fast her for 24 hours then feed a bland diet in small, frequent amounts until symptoms resolve. Transition slowly to her regular diet afterwards.
