The full answer
Chives (Allium schoenoprasum) are an Allium species. The Merck Veterinary Manual names chives with onion, garlic and leek, and describes Allium toxicosis in dogs as oxidative damage to red blood cells that can lead to haemolytic anaemia.
VCA Animal Hospitals states that all forms are poisonous to dogs: raw, cooked, dried, powdered and liquid preparations. Dried and powdered forms are more concentrated because the water has been removed.
This is different from ordinary stomach upset. Vomiting may happen early, but the more serious signs of anaemia — weakness, pale gums, fast breathing or a fast heart rate, and dark or red urine — can take several days to develop.
Chives are often hidden in other foods, such as cream-cheese spreads, dips, sauces, potato dishes and seasoning mixes. A food that contains chives needs the same caution as chives on their own.
Risks and Things to Know
- Allium compounds can damage red blood cells and cause haemolytic anaemia.
- Cooking does not make chives safe.
- Dried, freeze-dried and powdered chives are more concentrated than fresh.
- Signs can be delayed by several days, so a dog that seems fine may still need advice.
- ASPCA lists vomiting, weakness, a high heart rate, panting and blood in the urine among the clinical signs.
How Much Can Dogs Eat?
There is no amount of chives we would describe as suitable for a dog.
Keep chive plants, chopped chives and chive-seasoned foods out of your dog's reach.
How Should I Prepare It?
- Chives have no safe preparation for dogs.
- When sharing food from your own plate, check whether it was made with chives, onion, garlic or leek, including powders and spreads.
