Plants Poisonous to Dogs

Asparagus Fern

The Asparagus Fern is popular as a household plant despite technically being a weed. It looks almost fluffy, and is used to buff out and add color to flower arrangements.

Ingesting the berries is the biggest worry here, although repeated exposure to the plant can cause skin inflammation in the form of allergic dermatitis.

Danger Level: Low. Seek a vet’s advice if symptoms persist for more than a day after ingestion, or if symptoms persist after moving the plant out of the dog’s reach.

Symptoms: Vomiting, diarrhea, abdominal pain, and skin inflammation.


Flowering or not, Begonias are a lovely plant which adds spots of color to indoor and outdoor gardens.

The roots are the most toxic aspect of this plant; however, the leaves and stems also pose a risk if ingested. Humans, however, can eat the flowers!

Danger Level: Mild. Seek a vet’s advice if symptoms persist for more than a few hours or if the dog has eaten a large portion of the plant.

Symptoms: Vomiting, an intense burning sensation in the mouth, excessive drooling, and difficulty swallowing.


Mostly found in the wild, though sometimes in gardens as well, Cycads are highly toxic to dogs and humans.

The seeds are the deadliest part, with only three needed to cause a plethora of dreadful symptoms as well as death if left untreated.

Danger Level: High. Seek out a vet immediately!

Symptoms: Vomiting, yellowing eyes or skin (jaundice), paralysis, convulsions, liver failure, and gastrointestinal problems. There is a high chance of death or permanent nerve damage.


Ivy may offer a charming Italian Villa vibe to your home and garden, but it is also toxic to dogs.

Not only can ingesting the plant potentially cause your dog to become very ill, but any dust or particles brushed from the plant can cause irritation to the nose, mouth, and eyes.

Danger Level: High. Seek out a vet immediately!

Symptoms: Vomiting, respiratory distress, skin irritation, anemia, diarrhea, and convulsions. Death can occur in severe cases of respiratory distress.

Tomato Plant

Lots of people have vegetable gardens with tomatoes in them.

While the ripened vegetable (or fruit, depending on where you stand on the debate) is perfectly fine for dogs to eat, every other part of the plant is toxic. Basically, the green bits are dangerous.

Danger Level: Mild. If symptoms persist for more than two days, seek out a vet.

Symptoms: Vomiting, shaking, diarrhea, and disorientation.


A plant that sprouts little clusters of bright flowers, Milkweed is found mostly in the wild and is not kept in gardens.

Oddly enough, there are caterpillars that have evolved to ingest the toxic sap of this plant, which in turn makes the caterpillars and butterflies toxic too. Nature is weird.

Danger Level: High. Seek out a vet immediately.

Symptoms: Abnormal heartbeat, vomiting, diarrhea, excessive drooling, lethargy, and convulsions. Death is likely without a vet’s intervention.

Succulent Plants That are Poisonous to Dogs

Aloe Vera

One of the most common succulents around is Aloe Vera.

It’s durable enough to survive in just about any environment, making it a popular choice for gardeners, as it also has medicinal applications when prepared properly.

Danger Level: Medium. Seek a vet’s advice if symptoms persist for more than a few hours.

Symptoms: Vomiting, diarrhea, and tremors.

Poisonous Flowers

Angel’s Trumpet

This is a beautiful but deadly plant. Angel’s Trumpet is grown largely because it has medical properties, but also because its flowers are incredibly beautiful.

All parts of Angel’s Trumpet are toxic, and it is deadly to everyone, not just dogs.

Danger Level: High. Go to the vet immediately and do not touch the plant yourself.

Symptoms: Muscle weakness, dilated pupils, dry mouth, rapid pulse, fever, hallucinations, paralysis, convulsions, and falling to a comatose state. Death is a possibility.


Azaleas are highly popular in gardens for their bright colors and relatively easy cultivation.

However, they are very dangerous to dogs and can cause a whole plethora of issues – and even death.

Danger Level: High. Go to the vets immediately.

Symptoms: Vomiting, diarrhea, excessive drooling, paralysis, depression of the nervous system, and falling into a coma. Death is a possibility.

Baby’s Breath

It is a little strange that such a gentle sounding name was given to a plant that has the potential to poison dogs.

Baby’s Breath are delicate little flowers that are popular as indoor plants, in gardens, and in flower arrangements.

Danger Level: Mild. Seek a vet’s advice if symptoms persist for more than a few hours.

Symptoms: Vomiting and diarrhea.


Also known as Ranunculus, Buttercup flowers are mostly found in the wild, rather than cultivated in gardens.

Even to dogs, which will eat anything, the buttercup plant tastes bad – which should prevent all but the most tenacious (or stupid) of dogs from eating a dangerous amount.

Danger Level: Mild. Seek a vet’s advice if symptoms persist for more than a few hours.

Symptoms: Vomiting, diarrhea, and blisters on the skin and mouth.


Just about everybody has worn a carnation at some point in their life. They are beautiful flowers, both as outfit accessories and in gardens, but like so many things in nature, beauty can be deadly.

Ingestion and skin exposure can cause symptoms to arise. Be sure to dispose of carnations carefully, and place any flower arrangements well out of your dog’s reach.

Danger Level: Mild. Seek a vet’s advice if symptoms persist for more than two days.

Symptoms: Skin irritation, diarrhea, and mild gastrointestinal problems.


A hugely popular flower for the garden, Chrysanthemums come in a wide range of colors and bloom into attractive domes of petals come autumn.

Largely, ingesting the plant will cause a bit of unpleasantness, but overexposure and contact with the plant can cause extreme symptoms to arise as well.

Danger Level: Mild. Seek a vet’s advice if symptoms persist for more than two days.

Symptoms: Vomiting, diarrhea, excessive drooling, wooziness, and rashes.

Also known as Persian Violet, Cyclamen is a lovely looking flower commonly kept as an indoor plant.

Danger Level: High. Seek a vet’s advice if symptoms persist for more than a few hours.

Symptoms: Vomiting, excessive drooling, diarrhea, convulsions, and abnormal heartbeat. Death can occur in severe cases.


Daffodils may look pretty, but they are highly toxic to dogs – and even humans. Ingestion will cause death if treatment is not sought out ASAP!

Isn’t it strange that some of the most beautiful, and commonly sought after, flowers are actually some of the most poisonous on the planet?

Danger Level: Extremely high! Even the un-sprouted bulbs and water in the catcher at the bottom of a planter box is toxic to dogs.

If you see your dog drinking this water or eating the plant, take them to the vet immediately.

Symptoms: Vomiting, diarrhea, abdominal pain, abnormal heartbeat, excessive drooling, depression of the respiratory system, and severe skin irritations. Death is likely without a vet’s immediate intervention.


A popular plant for flower enthusiasts is the Gladiolus. Beautiful, yet struggling to make it through the colder months, these flowers are usually only found in carefully tended and curated gardens.

The bulb is the most toxic part of the plant, but the stem, leaves, and flowers will all cause symptoms to occur.

Danger Level: Moderate to High. A vet should be sought out immediately.

Symptoms: Vomiting, diarrhea, convulsions, abnormal heartbeat, and excessive drooling. Death is a possibility.


Lilies may be beautiful to have peppered throughout your garden or as the centerpiece of your dining table, but they are so dangerous to your dogs (and cats, although we aren’t covering them in this article).

Even just drinking the water from the planter can have deadly consequences.

Danger Level: High. A vet should be sought out immediately.

Symptoms: Vomiting, anemia, diarrhea, excessive peeing, excessive thirst, and kidney failure.

What to Do If Your Dog Eats a Toxic Plant

Stay calm!

Comfort your dog with a soothing tone of voice – but avoid high pitches, as that tells them that you are upset and will only distress them more.

Now, contact your vet and let them know about the situation, if possible. In emergency cases where your pooch is convulsing, struggling to breathe, or seems in great pain and distress, just get them in the car and head right on over.

Before heading out, if you cannot identify the plant, grab a sample of the plant they have been chewing on. This will be an important piece of information your vet will need to create a treatment.

What will happen next will depend on the severity of the poisoning. A short term or long term treatment plan may be needed, alongside a stomach pump.

And if things are truly dire? It may be kinder to have your beloved dog put to sleep rather than prolong their suffering. This is a worst case scenario, and only happens in the most severe cases of poisoning.

Keeping your pet safe is a priority! Educate yourself and create a wonderful environment for them to live out their lives with you.
