Dogs are not allowed to eat onions as they are toxic to them. Onions contain a compound called N-propyl disulfide which causes the breakdown and destruction of red blood cells in dogs, leading to anemia and potentially fatal outcomes. This toxicity applies to all parts of the onion including raw, cooked, fried, powdered forms, and even related plants like garlic, leeks, chives, and green onions. Symptoms of onion toxicity in dogs include decreased appetite, lethargy, pale gums, weakness, vomiting, diarrhea, elevated heart rate, and more. If a dog consumes onions, immediate veterinary care is necessary to prevent serious health issues.
