Dogs must not eat onions as they are highly toxic to them in any form—raw, cooked, powdered, or parts of the onion plant. The toxic compound in onions, called N-propyl disulfide, damages red blood cells, leading to a condition called hemolytic anemia, which can be fatal if untreated.
Risks and Symptoms
Even small amounts of onion can cause serious health issues depending on the dog’s size and breed. Symptoms of onion poisoning include pale gums, lethargy, weakness, vomiting, diarrhea, rapid breathing, red or brownish urine, and collapse. Immediate veterinary care is essential if ingestion is suspected, especially if symptoms appear.
Parts of the Onion
All parts of the onion, including flesh, leaves, juices, and powders, are toxic. Additionally, members of the Allium family such as green onions, chives, garlic, leeks, and shallots are equally harmful.
Safe Practice
To protect dogs from accidental ingestion, it is best to avoid giving any onions and securely store onions away from pets.
In summary, onions are dangerous and potentially deadly for dogs, and they should never be fed to them under any circumstances.
