Five stalks for a 12 kg dog is serious volume
At this quantity — roughly a small handful — the toxins in chives can overwhelm your dog's system much faster than tiny nibbles would. Their 12 kg body weight doesn't provide enough buffer for this amount, putting them at risk for acute haemolysis rather than gradual anaemia. The fact it happened just 15 minutes ago means we're in the window where fast action matters most.
Unlike with minor exposures, vomiting may start spontaneously within the hour as their body reacts to the irritants. Don't try to induce it yourself — the danger now is dehydration and electrolyte loss from vomiting combined with the blood cell damage already underway. Emergency vets have protocols to manage both safely.
Why speed matters more than visible signs
Waiting for symptoms like weakness or dark urine means waiting until substantial blood cell destruction has occurred. By acting now, your vet can administer supportive treatments that may reduce the toxin's absorption and protect organs from the coming cellular debris load.
Time also affects diagnostic options — bloodwork done within the first few hours establishes baselines that help track whether the damage is progressing over subsequent days. Some clinics might recommend hospitalisation for IV fluids to support kidney function as they process damaged cells.
The difference between raw and cooked matters here
Raw chives retain all their toxic compounds at full potency, whereas cooking can break some down. Your dog ate them raw, so none of those natural safeguards apply. The stalks also contain concentrated amounts in their white bases — if those were included in the five they ate, the dose is effectively higher than leafy tops alone.
This isn't like garlic where processing changes the risk — raw chives are among the most potent alliums for dogs because of how we typically grow and use them fresh. The small diameter of the stalks means more surface area was exposed to their digestive juices, releasing compounds faster.
What to bring with you to the vet
If possible, take a photo of the remaining chives in the bunch so the vet can estimate how much is truly missing. Note any garden pesticides or fertilisers used on them, as those could compound the issue. Bring their regular food bag too — some diets high in oxidants could worsen allium effects.
Prepare for possible blood tests by withholding food (but not water) unless directed otherwise. Know the last time they ate normally, as that affects how quickly the chives moved through their stomach. If they've had any prior anaemia or liver issues, mention those immediately — pre-existing conditions raise the stakes.
