12 plants that are poisonous to dogs

1. Lilies

Lilies are a major no-go for dog owners.
While they’re more commonly known for being toxic to cats, certain types like Peace, Tiger, and Daylilies can cause severe kidney damage in dogs, too.

2. Azaleas

These vibrant shrubs can cause vomiting, diarrhea, and even coma or death in rarer severe cases. Just a few leaves can make your dog ill.

3. Oleander

Oleander is highly toxic. Ingesting even a small amount can lead to serious issues like heart failure.

4. Sago Palm

Often found indoors, the Sago Palm is extremely poisonous. Its seeds are the most toxic part, causing liver failure and potentially death.

5. Tulips

Tulip bulbs contain toxins that can cause mouth and stomach irritation, leading to drooling, diarrhea, and vomiting.

6. Foxgloves

Foxgloves could affect your dog’s heart. Symptoms of poisoning include heart rate changes, vomiting, and lethargy.

7. Autumn Crocus

Ingesting Autumn Crocus can cause severe vomiting, gastrointestinal bleeding, liver and kidney damage, and respiratory failure.

8. Yew

Yews are often used in landscaping and can cause central nervous system effects like trembling, incoordination, and difficulty breathing.

9. Rhododendron

Similar to Azaleas, this poisonous perennial can cause vomiting, diarrhea, drooling, and potential heart failure in dogs.

10 Daffodils

Daffodil bulbs are toxic, causing vomiting, diarrhea, and even severe heart problems.

11. Hydrangeas

With their large blooms, Hydrangeas are deceptively dangerous and may cause stomach upset, vomiting, and lethargy if your dog ingests them.

12. English Ivy

This is a climber to avoid – the plant can cause vomiting, abdominal pain, hypersalivation, and diarrhea.

Recognising the signs – symptoms of plant poisoning

Identifying plant poisoning early could save your dog's life.

Symptoms vary but often include:

Consider switching up your house plants if any of yours are toxic to animals.
