Will my dog be okay after eating liver cooked in an onion pan?

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.

Yes, carry on monitoring him for another day or two. If you notice any signs of poisoning, like vomiting, diarrhea, weakness, lack of appetite, take Hugo to your regular vets for a check-up. However, the amount of onion he ate (it was not much for his size) and the fact that 16hrs after ingestion he looks ok means that most likely he is out of the woods.

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.

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 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 thank you for your question! If Dudley did not ingest any actual onions, then he should be just fine. The onion flavor in the fish should not be toxic to him. I would, of course, in the future avoid feeding him any actual onions! I hope this helps!

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!
