What Flowers Are Toxic to Dogs?

A rose is a rose is a rose — but sometimes, it’s also poison. While the right flowers can brighten up a home and add a touch of nature’s beauty to the interior of your house or apartment, or lend color to your garden, certain flowers also can pose a risk to animals. And if you’re a pet parent, you’ll want to know which flowers are safe and which can be harmful to your dog.

Many common flowers, including lilies, daffodils, and hydrangeas, can present potential health risks to dogs. A 2023 study found that ingestion of poisonous plants at home is relatively common for pets and responsible for five to 10 percent of all inquiries at toxicology centers. In 2025, the ASPCA Poison Control Center found that plant and fungi ingestion covered 7.5 percent of all exposures that were called in to the center.

Thriving plants are spring’s whole thing—but these offenders can be perilous to pets.

Why are some flowers dangerous for dogs? 

Some plants and flowers contain toxins that can be dangerous if your dog eats them. This toxicity ranges from mild to severe, depending on the plant. Sometimes, a flower will only cause mild mouth irritation or gastrointestinal distress, but in other cases, toxic plants can cause severe and life-threatening symptoms, such as labored breathing or even seizures. 

“There are many different reasons a plant may be toxic to dogs,” Dr. Fox says. “This usually comes down to compounds in the plants that cause serious injury to animals when they eat them or come into contact with them.” 

What should I do if my dog has eaten a toxic flower? 

If you suspect your dog has consumed something toxic, call your vet or animal poison control center immediately. The ASPCA Poison Control Center at 888-426-4435 and the Pet Poison Helpline at 855-764-7661 are available 24/7. 

Diagnosing plant poisoning in dogs

Bring as much information as you can to your vet or the emergency clinic, including what type of plant your dog consumed, how much, and how long ago the incident occurred. Your vet will run tests to determine the best route for treatment. Never induce vomiting in your dog without the explicit permission of your veterinarian. 

Symptoms of plant poisoning in dogs

Be aware of the symptoms of plant poisoning in dogs and look out for any of the following symptoms in your pet if you think they may have consumed a toxic plant: 

• Vomiting or diarrhea

• Seizures

• Difficulty breathing or rapid breathing

• Lethargy

• Loss of appetite

• Uncoordinated movements

• Jaundice (yellowing of the skin or eyes)

Treatment

The vet may induce vomiting in your dog to remove the toxins or administer a liquid suspension of activated charcoal, which can help absorb the poison. For more severe cases, intravenous fluids and medications may be required. 

How to prevent plant poisoning

The best way to prevent plant poisoning in your dog is to learn which flowers and plants pose a toxic risk. You should also know the symptoms of toxicity, so you can notice immediately if your dog needs medical care from ingesting a poisonous flower. Find ways to keep plants away from your pet and, if possible, keep all potentially toxic plants and flowers out of your home and garden. 

Are all parts of a toxic flower poisonous to dogs? 

Some flowers are dangerous to dogs regardless of which part they ingest, while others only have toxins in the bulbs, stems, or flowers. Be sure to research which flowers are poisonous to your pets and keep them out of your dog’s reach. 

How do I stop my dog from eating toxic flowers?

The best way to prevent your dog from eating potentially poisonous flowers is to keep these plants out of your home. You can also elevate plants with hanging planters or on high shelves out of your dog’s reach or fence off areas of your garden to keep your dog out.

FAQs

What happens if my dog eats a toxic flower?

Depending on the flower and how much they consume, your dog could experience mild gastrointestinal distress or more serious symptoms like tremors or organ damage. If your dog consumes a toxic plant, contact your vet immediately.  

Are toxic flowers poisonous to dogs if they smell them? 

For the most part, no. They have to consume the plant to experience any negative effects. However, there are exceptions. However, highly toxic flowers, like lilies, can make dogs sick even if they smell them. This is likely because they get pollen on their nose that they then lick and ingest and this can make them very sick.
