Question: are leeks good for dogs?
Answer: Leeks are part of the Allium family (which also includes onion, chives, and garlic) and are poisonous to dogs and cats. Garlic is considered to be about 5-times as potent as onion and leeks. Certain breeds and species are more sensitive, including cats and Japanese breeds of dogs (e.g., Akita, Shiba Inu).
