Plants & flowers that are dangerous for dogs

Updated July 19, 2017

Planting a garden is lovely and enjoyable, but for people with dogs, gardening may be a source of anxiety, especially since some plants are poisonous to dogs. However, you can create a dog-friendly yard by avoiding plants that may harm your buddy.


Planting certain bulbs in your garden may be a bad idea, especially if your dog likes to dig. Iris, hyacinth, tulips and narcissus bulbs poison the ground around them after a period of time, causing vomiting, diarrhoea and anorexia in dogs.

Flowering Plants and Perennials

Flowering plants and perennials such as foxgloves, tomatoes, morning glories and hydrangeas have poisonous leaves harmful to dogs. If eaten, these plants may cause cardiac arrest and death in dogs. Poinsettias may cause mouth and stomach irritation, often leading to severe vomiting.


Branching ivy and English ivy are among the many types of dangerous ivy species. With ivy, the leaves are the most poisonous part of the plant and cause hypersalivation, stomach pain and diarrhoea.


Yew, avocado and Chinaberry are among the trees that cause seizures, cardiac failure and muscle tremors in dogs. Other poisonous trees include macadamia, lacy tree and schefflera, which cause a burning sensation in the dog's mouth and problems swallowing.

Uncategorized Plants

Planting bird of paradise, caladium, clematis and azaleas are a bad idea if your dog likes to nose around in the garden. Some of their effects include drowsiness, vomiting, depression, coma, leg paralysis, weak heartbeat, nerve damage and even death.

Preventing Harm

Building a sturdy fence or not planting plants dangerous to dogs will spare your pet from illness or death. If you have these plants in your garden, build a dog run or constantly watch your dog to make sure he does not ingest the flowers.
