Gardening is a popular pastime in the UK, offering beauty and tranquillity to many homes. However, dog owners must know that some common plants can be harmful or even fatal to our furry friends. In this article, we'll explore which plants are toxic to dogs, the symptoms of poisoning, and how to keep your canine companion safe.
Highly Toxic Plants
Autumn Crocus (Colchicum autumnale)
Autumn Crocus, also known as Meadow Saffron, contains colchicine, which can cause severe gastrointestinal distress, liver and kidney damage, respiratory failure, and even death in dogs. Every part of the plant, especially the bulbs and seeds, is toxic.
Azalea/Rhododendrons (Rhododendron species)
Azaleas and rhododendrons contain grayanotoxins, which can disrupt normal cardiac function in dogs. Symptoms of ingestion include vomiting, drooling, diarrhoea, weakness, and, in severe cases, coma or death.
Foxgloves (Digitalis species)
Foxgloves are beautiful but deadly. They contain digitalis glycosides, which can cause severe cardiac disturbances, including heart failure. Early signs of poisoning include vomiting, drooling, and lethargy.
Lily of the Valley (Convallaria majalis)
This plant contains cardiac glycosides, which are highly toxic to dogs. Symptoms of ingestion include vomiting, diarrhoea, a drop in heart rate, seizures, and even death.
Oleander (Nerium oleander)
Oleander is highly toxic, containing compounds that affect the heart. Even small amounts can be fatal. Symptoms include drooling, vomiting, decreased heart rate, and potential death.
Yew (Taxus species)
All parts of the yew plant, including the berries, are highly toxic to dogs. They contain taxine alkaloids, which can cause sudden death due to heart failure. Symptoms before death include trembling, incoordination, and difficulty breathing.
Other Toxic Plants
Bluebells (Hyacinthoides species)
Bluebells contain glycosides that can cause abdominal discomfort, heart problems, and even paralysis in dogs. Symptoms include drooling, vomiting, and diarrhoea.
Daffodils (Narcissus species)
Daffodils contain lycorine, an alkaloid with strong emetic properties (causes vomiting). Ingestion can lead to severe vomiting, diarrhoea, abdominal pain, and even cardiac arrhythmias or respiratory distress in severe cases.
Holly (Ilex aquifolium)
While holly berries are particularly dangerous, all parts of the plant can be harmful. They contain saponins, which can cause vomiting, diarrhoea, and severe gastrointestinal distress.
Hyacinths (Hyacinthus orientalis)
Hyacinths contain alkaloids that can cause intense vomiting, diarrhoea, and tremors in dogs. The bulbs are the most toxic part.
Ivy (Hedera helix)
Ivy contains saponins, which can lead to excessive drooling, vomiting, diarrhoea, and abdominal pain. Skin contact with ivy can also cause irritation.
Laburnum (Laburnum anagyroides)
Laburnum contains cytisine, which can cause intense vomiting, salivation, excitement, and convulsions. In severe cases, it can be fatal.
Rhubarb leaves (Rheum species)
While the stalks of rhubarb are safe, the leaves contain oxalic acid, which can cause kidney failure. Symptoms include drooling, vomiting, diarrhoea, and tremors.
Tulips (Tulipa species)
Tulips contain tulipalin A and B, which are toxic to dogs. Ingestion of the bulbs is the most dangerous part, and symptoms include drooling, vomiting, and diarrhoea.
Common Houseplants to Avoid
Aloe Vera
While aloe vera is known for its healing properties for humans, it contains saponins and anthraquinones that can cause vomiting, diarrhoea, lethargy, and tremors in dogs.
Dumbcane (Dieffenbachia species)
Dumbcane contains insoluble calcium oxalates, which can cause intense oral irritation, drooling, vomiting, and difficulty swallowing.
Peace Lily (Spathiphyllum)
Peace lilies contain calcium oxalate crystals, which cause oral irritation, drooling, vomiting, and difficulty swallowing.
Philodendron
Philodendrons contain insoluble calcium oxalates that cause oral irritation, drooling, vomiting, and difficulty swallowing in dogs.
Poinsettia (Euphorbia pulcherrima)
Poinsettias are known for being toxic, although they are generally less harmful than others. They can still cause mild gastrointestinal irritation, such as vomiting and drooling.
Symptoms of Plant Poisoning in Dogs
The symptoms of plant poisoning can vary depending on the plant and the amount ingested. Common symptoms to watch for include:
- Drooling
- Vomiting or diarrhoea
- Lethargy
- Increased thirst or urination
- Skin irritation or rashes
- In severe cases, seizures or collapse
