Onion or garlic (Allium spp.) including those that are fresh as well as those dried for use as spices.
Garlic and onion are used as flavor enhancers in food. Some human baby foods have onion in them, and it is not recommended to feed them to pets. In dogs and cats, garlic and onion can cause Heinz body anemia, resulting in a breakdown of the red blood cells and anemia. The very small amounts of garlic that are present in some commercial pet foods have not be shown to cause any problems.
The bulbs, bulbets, flowers, and stems of the garlic and onion are all poisonous.
Unknown. Cats appear to be more sensitive than dogs.
Vomiting, diarrhea, anemia, discolored urine, weakness, liver damage, allergic reactions, asthmatic attacks, and in case of skin exposure, contact dermatitis.
