Lilies
NOT RECOMMENDED
Most true lilies are not highly toxic to dogs, but they can cause vomiting and diarrhoea. They are extremely dangerous for cats.
What to do
Contact your vet if your dog ate lilies or is showing symptoms.
When to contact a vet: Seek vet advice if symptoms persist; this is an emergency for cats, not usually for dogs.
Symptoms to look for
- vomiting
- diarrhoea
- drooling
- lethargy
- loss of appetite
Why
True lilies in the Lilium and Hemerocallis families are best known for causing fatal kidney failure in cats. In dogs, they are more likely to cause mild stomach upset. However, some lily-like plants such as lily of the valley are highly toxic to dogs. Because of the risk to cats and the difficulty of identifying lilies, it is safest to keep all lilies away from pets.
