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.
