Short answer

No. Onions, garlic, chives and leeks belong to the Allium family, which is poisonous to dogs. They can upset the stomach and damage red blood cells, leading to anemia. Risk depends on the amount eaten, and Japanese breeds such as Akitas and Shiba Inus are more sensitive. If your dog eats any, call your vet or a pet poison hotline.
