Symptoms of hyacinths poisoning in dogs

  • Vomiting
  • Diarrhea, sometimes with blood
  • Drooling
  • Depression
  • With large bulb ingestion: tremors and breathing changes

Why hyacinths are toxic to dogs

These compounds irritate the mouth, esophagus and stomach. They are concentrated in the bulb, so a pet that nibbles petals usually has mild signs, while a dog that eats bulbs can get severe vomiting, a fast heart rate and breathing changes. Whole bulbs can also cause a blockage.

What to do if your dog ate hyacinths

  1. Remove plant pieces from your dog's mouth and move dogs away from the plant. Wipe sap or pollen off the fur and paws with a damp cloth.
  2. Call your vet or animal poison control for advice: ASPCA Animal Poison Control: (888) 426-4435 · Pet Poison Helpline: (855) 764-7661.
  3. Identify the plant. Take a photo or bring a piece (or the plant label) to the vet, and estimate how much was eaten and when.
  4. Do not make your dog vomit unless a vet tells you to. Home remedies such as hydrogen peroxide or salt can cause serious harm.
  5. Watch for vomiting, diarrhea, sometimes with blood, drooling. Go to a vet if signs are severe, last more than a day, or your dog has trouble breathing or swallowing.

Treatment and outlook

For petals or leaves, supportive care is usually enough. After bulb ingestion, a vet may induce vomiting, give fluids and anti-nausea medicine, and monitor heart rate and breathing.

How to keep your dog away from hyacinths

  • Place hyacinths on high shelves or in hanging planters out of reach of paws and tails, or in a room your dog cannot enter.
  • Give your dog something better to chew: chew toys and puzzle feeders reduce boredom chewing.
  • Pick up fallen leaves, petals and pollen promptly, and empty vases where pets can reach them.
  • In the garden, fence off beds, supervise dogs that dig, and store bulbs in a closed container before planting.
