What Flowers Are Poisonous To Dogs

Many common flowers are poisonous to dogs and can cause a range of symptoms from mild irritation to severe illness or even death. Here are some flowers to be particularly cautious about if you have dogs:

Azaleas and Rhododendrons
- Symptoms: Vomiting, diarrhea, drooling, lack of appetite, and in severe cases, coma or death.
Tulips and Hyacinths
- Symptoms: Drooling, nausea, vomiting, diarrhea. More severe symptoms include increased heart rate and trouble breathing (particularly from bulb ingestion).
Daffodils (Narcissus)
- Symptoms: Vomiting, diarrhea, abdominal pain, and possible cardiac arrhythmias or respiratory depression.
Lilies (many types, including Easter Lily, Tiger Lily, and others)
- Symptoms: Gastrointestinal distress, lethargy, and loss of appetite. Lilies are extremely toxic to cats and can cause severe kidney failure, but dogs can also have serious reactions.
Oleander
- Symptoms: Vomiting, decreased heart rate, dilated pupils, tremors, and potentially fatal in severe cases.
Sago Palm (not a flower, but often found in gardens)
- Symptoms: Vomiting, diarrhea, seizures, liver failure, and can be fatal.
Foxglove
- Symptoms: Drooling, nausea, vomiting, diarrhea, heart issues (e.g., arrhythmias), and potentially death.
Cyclamen
- Symptoms: Intense gastrointestinal issues such as severe vomiting and possibly death (particularly toxic are the roots).

Begonias

It’s essential for dog owners to keep these toxic plants out of reach of their pets and to be aware of the symptoms of plant toxicity. If you suspect your dog has ingested a poisonous flower, contact your veterinarian or an emergency animal poison control hotline immediately. Quick intervention can mean the difference between life and death.
