Onions contain thiosulfate, which is toxic to dogs because they lack the enzyme to digest it. Eating onions can lead to a condition known as hemolytic anemia, where red blood cells rupture at an accelerated pace. While a very small piece may not result in immediate harm, it's important to monitor for any unusual behavior or symptoms such as vomiting, diarrhea, or lethargy. If you note any changes or have concerns, consulting with a veterinarian is recommended.
