My 20 kg dog ate a tulip bulb — is that more toxic for him than the onion he got into last month?

Short answer

Both are toxic, but they attack the body differently. Onions damage red blood cells, causing anaemia that takes days to show. Tulip bulbs contain different toxins that irritate the mouth and gut immediately, causing drooling, vomiting, and abdominal pain within hours. For a dog his size, a single bulb is a concern but not a guaranteed crisis. Call your vet or the ASPCA poison line at 888-426-4435 right now, tell them it's a tulip bulb and his weight, and follow their advice. Don't wait to compare — the clock started when he dug it up.

Why is this dangerous?

Tulips and hyacinths contain tulipalin A and B, and daffodils contain lycorine and other alkaloids. The concentration is highest in the bulb, lower in the stem and leaves.

Dogs are poisoned most often in spring when they dig up newly planted bulbs, or in winter when bulbs are forced indoors in pots.

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

  • Drooling, lip smacking, pawing at the mouth
  • Vomiting, sometimes repeated, and diarrhoea
  • Abdominal pain, not eating, lethargy
  • Wobbliness or tremors after eating several bulbs
  • Heart rhythm changes, low blood pressure and collapse in large ingestions

What to do right now

  1. Call your vet or a poison line and say how many bulbs and which flower.
  2. Rinse the mouth with water and wipe any plant sap off the fur and paws.
  3. Do not induce vomiting yourself — ask the vet first, especially if the pet is already vomiting.
  4. Dig up and fence off bulbs; keep forced pots on a shelf a pet cannot reach.
If your pet shows any of the signs above, go to the nearest emergency vet now and call ahead.
