Which Plants are Poisonous to Dogs?

There are a large number of plants and flowers found in backyards all over the world that are poisonous to dogs. Ingesting some of these plants will cause the dog to be extremely sick, while others can be fatal. It is therefore very important for dog owners to be aware of what plants are dangerous to dogs, and if these plants are growing in their backyard.

The following guide will detail the most common poisonous plants, and will also suggest alternative plants, such as bamboo or blueberries, that can be grown in backyards and are not harmful to dogs.

Plants Poisonous to Dogs

Dogs have a very different digestive system to humans, and they are unable to process many things we can eat. Some of these, like chocolate, are harmful to canines and can even lead to death. Dog owners also need to be aware of the many flowers and plants found in backyards that are harmful to dogs, and if found these should be removed immediately.


The problem with planting bulbs in a backyard is dogs love to dig them up and eat them. While the actual plant may not be toxic to the dog, the majority of bulbs are extremely poisonous and will cause instant vomiting. Below are some of the more commonly found bulbs that are harmful to dogs.


These are extremely toxic to dogs, and ingesting an amaryllis bulb can prove fatal. Amaryllis is known by a number of different names including Belladonna lily, Saint Joseph lily and Naked Lady. Symptoms include vomiting, depression, diarrhoea, anorexia and tremors.


These are very common and are popular with gardeners across the world. However, crocus bulbs are very poisonous and symptoms include oral irritation, bloody vomiting, diarrhoea and damage to multiple organs.


Also known as sowbread, ingesting this type of bulb can cause a dog gastrointestinal inflammation and death.


Not only are the bulbs poisonous to dogs, but also the flowers and the leaves. Symptoms will include convulsions, shivering, dermatitis, severe gastrointestinal disorders and cardiac arrhythmias.


All of this plant is poisonous to a dog, and consuming it can cause intense vomiting and diarrhoea with blood, heavy depression and tremors.


The iris is also known as the snake lily and water flag, and this will cause the dog to experience vomiting, depression, hyper salivation and abdominal pain.


Ingesting a tulip bulb will cause a dog to experience vomiting, hyper salvation and lack of appetite.


Many plants kept around the house in containers are also poisonous to dogs, and dog owners should avoid these plants unless they are kept in hanging baskets or in areas of the house inaccessible to the dog.

Aloe Vera

This plant is known for its beneficial qualities for humans, but ingesting it can cause a dog to experience symptoms such as depression, anorexia, tremors and a change in the colour of the dog’s urine.


All parts of this plant are toxic to dogs, and can cause serious illness if it is even chewed. Symptoms include vomiting, abdominal pain, increased and abnormal heart rate, and if the plant is swallowed and it can prove fatal to the dog.

Castor Bean Plant

The leaves of this plant are poisonous, but it is the actual castor beans that are most toxic to canines. Swallowing the beans can cause the dog to experience extreme irritation of the mouth and throat, an increase in thirst, vomiting, diarrhoea, convulsions and kidney failure.

Corn Plant

These are also known as cornstalk plant, dracaena and ribbon plant, and if this plant is ingested it will cause the dog to experience symptoms such as vomiting with blood, depression, lack of appetite and increased salivation.

Jade Plant

The jade plant is also known as baby jade, dwarf rubber plant, jade tree and the Chinese rubber plant. Symptoms from ingesting this plant will include vomiting, depression, ataxia, and a reduced heart rate.

Vegetables and Fruits

Dog owners that grow vegetables or fruits in their backyard need to ensure that the vegetable patch is cordoned off and the dog cannot get into it. The following are the vegetables and fruits most poisonous to dogs grown in backyards today:


Grapes are one of the most poisonous things a dog can eat, so it’s advised that dog owners avoid growing this fruit. Dog owners should also take special care if grapes are kept in the house, as a small portion will cause instant kidney failure and can prove fatal. The same goes for raisins and prunes.


Ingesting onions will cause the dog to experience gastrointestinal pain, anaemia and hemoglobinuria.


Ingesting mushrooms will cause acute gastric effect, serious liver and kidney damage, abdominal pain, nausea and vomiting.


The fruit, plant and pips are toxic to dogs, and symptoms include difficulty in breathing, an accumulation of fluid in the chest and vomiting and diarrhoea.

The first thing a dog owner should do if they believe their dog has been poisoned is to identify what it has eaten. The next step is to then try and induce vomiting. The best way to do this is mix three percent hydrogen peroxide with some vanilla ice cream and give it to the dog to eat. Owners should mix one tablespoon of hydrogen peroxide for every ten pounds of body weight, and should never use peroxide more than three percent in strength.

If the dog has eaten one of the more fatal pants then they must be taken to a vet immediately.
