A Guide to Toxic and Non-Toxic Plants for Dogs
Summary: Causes, Symptoms, and Treatments of Plant Toxicity in Dogs
Dogs are naturally curious animals, often exploring their environment by chewing on plants. While some plants are harmless, others can be poisonous and potentially life-threatening if ingested. Understanding which plants are toxic and which are safe is crucial for dog owners to prevent accidental poisoning.
Causes of Toxicity: Plant toxicity occurs when a dog ingests a toxic plant or part of it, such as leaves, flowers, stems, seeds, or roots. The toxic compounds in these plants can cause a range of adverse effects depending on the type of plant and the amount ingested. Some plants contain toxins that can affect the gastrointestinal system, while others may impact the cardiovascular, neurological, or respiratory systems.
Symptoms of Plant Toxicity: The symptoms of plant toxicity in dogs vary widely based on the plant ingested. Common symptoms include:
- Gastrointestinal distress: Vomiting, diarrhoea, drooling, loss of appetite
- Neurological symptoms: Tremors, seizures, lethargy, disorientation
- Respiratory issues: Difficulty breathing, excessive coughing, wheezing
- Cardiovascular symptoms: Irregular heartbeat, low blood pressure, shock
- Skin irritation: Redness, swelling, itching if the plant comes into contact with the skin
Treatment: If you suspect your dog has ingested a toxic plant, it is essential to seek veterinary care immediately. Treatment may include:
- Inducing vomiting (only under veterinary supervision)
- Administration of activated charcoal to absorb toxins
- Intravenous fluids to prevent dehydration and support organ function
- Medications to manage symptoms such as anti-nausea drugs, anticonvulsants, or heart medications
- Hospitalisation for severe cases to provide intensive care and monitoring
The Most Poisonous Plants for Dogs
Hydrangea
Signs and symptoms of hydrangea poisoning:
- vomiting
- lethargy
- diarrhoea
If you suspect your dog has ingested any part of a hydrangea plant, it’s crucial to contact your vet immediately. The earlier treatment is initiated, the better the chances of a full recovery. Early intervention can involve inducing vomiting, administering activated charcoal to absorb toxins, and providing supportive care to manage symptoms and prevent complications.
Lilies
Signs and symptoms of lily poisoning:

- abnormal heart rhythms.
If your pet consumes larges doses of this plant it can be fatal. We advise that you seek veterinary care as soon as possible if you think your pet has consumed this plant.
Angel’s trumpets
Many people own this plant without realising how harmful it is to their pets since it produces beautiful blooms. While most pets are deterred from nibbling on the leaves by their strong odour, some creatures are not.
Signs and symptoms of poisoning include:
- behavioural changes
- disorientation
- dilated pupils
- hyperthermia
- loss of appetite
- change in heart rate

Tulips
When spring comes around, these beautiful seasonal flowers bloom beautifully in our gardens, and while they don’t look harmful, if your dog goes digging, they may discover the tulip bulbs. The risk comes when your dog consumes the planted bulbs since they contain the highest levels of toxic chemicals.
Tulip Poisoning Signs

If you notice any of these signs, contact your vet and monitor your pet closely.
Bluebells
Bluebells are a spring favourite and is a common flower that you may find on woodland walks, in your garden and even on the sides of the road. Bluebells contain a toxin that affects the heart, and are poisonous to dogs.

- vomiting
- diarrhoea
- drooling

Foxgloves
All parts of the foxgloves plant are poisonous to dogs, cats, and even humans. These toxins, called cardiac glycoside toxins, affect the heart by disrupting its internal balance.
Signs and symptoms of foxglove poisoning:
- nausea
- tremors
- collapse
If you believe your dog has ingested or chewed a piece of this plant, treat it as a medical emergency and contact your vet as soon as possible. Foxglove poisoning lacks an antidote; thus, supportive therapy becomes the primary treatment approach.
Garden Hazards for Pets
To ensure that your pets don’t try to eat or nibble on your home plants while you’re away, it’s best to keep them out of reach. Additionally, keep an eye on your dog to make sure they haven’t discovered any plants that might endanger them when they’re on walks or in the garden. Keeping them on a lead would make this easier when walking them.
