Symptoms of dahlias poisoning in dogs

  • Mild vomiting and diarrhea
  • Mild skin irritation (dermatitis)

Why dahlias are toxic to dogs

The specific toxin has not been well characterized, but the plant irritates the gut and sometimes the skin.

What to do if your dog ate dahlias

  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 mild vomiting and diarrhea, mild skin irritation. Go to a vet if signs are severe, last more than a day, or your dog has trouble breathing or swallowing.

Treatment and outlook

Supportive care is usually enough. Call your vet if vomiting or diarrhea lasts more than a day.

How to keep your dog away from dahlias

  • Place dahlias 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.
