Spring onions, white or red onions, garlic and leeks are from a group of plants called alliums, which are all toxic to dogs and cats. If ingested, they can irritate your pet’s stomach and in more serious cases, damage red blood cells and cause anemia.
All parts of the plant are poisonous, whether raw or cooked. Immediate veterinary advice is essential if your pet consumes them.
