Plants toxic to dogs

Garden issues

Yard plants to avoid

Keep these common plants out of your dog’s way:

  • Daffodils
    • The flowers, leaves and bulbs can cause abdominal pain, vomiting and diarrhea.
    • In severe cases, cardiac arrhythmias and respiratory problems may occur.
    • Bulbs planted with bone meal will attract dogs.
  • Lily of the valley 
    • Dogs who eat lily of the valley may experience cardiac arrhythmias, decreased heart rates and seizures.
  • Tulips and hyacinths 
    • The bulbs are toxic.
    • Mild cases show drooling and some vomiting. 
    • If dogs eat too many, they may show an increase in heart rate.
  • Oleander
    • If your dog chews on leaves, flowers or branches, then they may suffer from a decreased heart rate, which can be fatal.
  • Azaleas
    • These can be fatal if your dog even chews on leaves.
    • Be aware of initial gastrointestinal signs, which, when untreated, can lead to coma and even death.
