My 15 kg dog just chewed a tulip bulb, not an onion. Which is the bigger emergency and what's the difference?

Short answer

Tulip bulbs are a bigger immediate emergency. Onions cause red blood cell damage that takes days; tulip bulbs contain chemicals that burn the mouth within hours and can cause acute kidney failure. Watch for your dog pawing at its mouth or drooling heavily in the next two hours — that's the corrosive irritation starting. Call your vet or the ASPCA Animal Poison Control Center (888-426-4435) now and bring the chewed bulb with you if you can. Do not try to make him vomit.

Why tulip bulbs are dangerous

Tulip bulbs contain tulipalin A and soluble oxalates that irritate the mouth and damage the kidneys, leading to rapid systemic toxicity.

The chemicals cause corrosive burns in the oral cavity and can precipitate acute renal failure if absorbed.

Why speed matters

Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.

Signs to watch for

  • Repeated vomiting starting 1-3 hours after chewing the bulb
  • Excessive drooling and pawing at the mouth within 2-4 hours
  • Bloody diarrhea appearing 4-8 hours later
  • Weakness and stumbling by the evening
  • Increased thirst and frequent urination later indicating kidney stress

What to do right now

  1. Call your vet or the ASPCA Animal Poison Control Center right away
  2. Bring the bulb or a clear photo so the clinic can identify the plant
  3. Keep your pet warm and watch for vomiting, diarrhea or changes in urination
  4. Do not induce vomiting because the oxalates can cause further mouth irritation
  5. If safe, rinse the mouth with water and prevent any further access
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
