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.

Consumption of as little as 15-30gm/kg of onion has resulted changes in the blood of dogs who eat it. Onion toxicities are noted in animals that ingest more than 0.5% of their body weight. That would be like a 20 pound dog eating 1/4th of a cup of onions. For Abigail, she would have to ingest around 1/8th of a cup in order to see toxic signs. Given that a 1cm piece of onion isn't enough to make 1/8th of a cup, she should be fine. Just make sure she doesn't get any more! Best of luck, I hope this helps!

Oh no, that wasn't good that Akamaru ate onions! It can take as little as 15 to 30 g/kg to cause toxicity in her. I'm not sure how much she weighs, but if it was a small quantity and she's is likely a large dog being a GSD, a small quantity won't do any damages. I would have her seen by a vet in the morning to be safe, however, but you can always take her into a clinic now to be sure she is ok.
