Chives are a true Allium, named alongside onion and garlic in poison-control guidance for the same reason: they damage red blood cells and can cause anemia. Because they arrive as a garnish, the usual problem is repeated small exposures.

Why Chives is dangerous
Chives are a true Allium, named alongside onion and garlic in poison-control guidance for the same reason: they damage red blood cells and can cause anemia. The catch is that chives arrive in small quantities, as a garnish, in herb butter, on a baked potato, so the usual problem is repeated small exposures rather than one big one. Signs of anemia can take several days to appear, so a dog that seems fine that evening is not cleared.
Signs to watch for
Weakness, pale gums, dark or reddish urine, lethargy, rapid breathing, reduced appetite, vomiting
What to do next
Note the amount and form and call your vet, and mention if your dog has had chives more than once recently, because the effect builds.
Chives rarely cause a single dramatic exposure, which is exactly why they get overlooked.
1. The cumulative problem
Allium damage to red blood cells accumulates, so a scatter of chives on dinner scraps several evenings running can matter more than one larger accident. The other trap is delayed onset: red-cell changes begin within about a day, but visible anemia can take several more, so an unremarkable evening proves nothing.

FAQ
How much Chives is dangerous?
Toxic by weight, and effects can take days to show. A single chive fragment on a plate is low-risk for a large dog; a herb-butter portion or a regular garnish habit is not.
Can I treat this at home?
A trace once, in a big dog, is usually low-risk to monitor. Anything more needs a call, because you cannot see anemia developing.
When should I call the vet?
Any real amount, a small dog, an Akita or Shiba Inu, repeat exposures, or any pale gums or dark urine.
