Are chives toxic to dogs?

Chives look delicate, but they contain the same sulfur compounds as onion and garlic. Once digested, these compounds damage the membranes of red blood cells, which then break down faster than the body can replace them. Some references consider chives among the more potent members of the family.

The effect depends on the amount eaten relative to body weight, so small dogs are at greater risk.

Chives turn up in cream cheese spreads, sour cream and chive dips, potato salad, scrambled eggs, omelettes, soups and savory scones. Pots of chives on kitchen windowsills and herb gardens are easy for dogs to reach, and puppies sometimes chew the grass-like leaves.

Stomach upset, such as drooling, vomiting or diarrhea, may appear within a day. Signs of anemia, including tiredness, pale gums, fast breathing, reluctance to walk and red or brown urine, often take several days to develop. Repeated small amounts over time can also cause problems.

Chives are perennial and come back every spring. Their purple pompom flowers are edible for people but carry the same risk for dogs. Grow chives in a raised bed, a hanging planter or a part of the garden your dog cannot reach, and clear up clippings after harvesting.

For a green sprinkle on your dog's food, choose a herb that is not in the onion family, such as parsley in small amounts, basil, dill or coriander. These give color and scent without the risk to red blood cells.
