Toxicity to pets
Chives belong to the Allium family (which also includes onion, garlic, and leeks) and are poisonous to dogs and cats. Certain breeds and species are more sensitive, including cats and Japanese breeds of dogs (e.g., Akita, Shiba Inu). Toxic doses of chives can cause damage to the red blood cells (making them more likely to rupture) leading to anemia. GI upset can also occur (e.g., nausea, drooling, abdominal pain, vomiting, diarrhea). Other clinical signs of anemia can also occur including lethargy, pale gums, increased heart rate, increased respiratory rate, weakness, exercise intolerance, and collapse. Signs of chive poisoning can be delayed and not apparent for several days. While tiny amounts of these foods in some pets, especially dogs, may be safe, large amounts can be very toxic.
Common signs to watch for:
- Oral irritation
- Abdominal pain
- Elevated heart rate and respiratory rate
- Exercise intolerance
- Pale gums
