Frequently asked questions
What should I do if my dog ate a toxic plant?
If you think your pet has eaten a toxic plant, call your vet or the nearest emergency vet and bring the plant or a photo. Don't make your pet vomit unless the vet tells you to.
Are all the plants on this list deadly to dogs?
No. Many only cause mouth irritation, drooling, vomiting or diarrhoea; others, such as sago palm or oleander, can be very serious. It depends on the plant and how much was eaten. If in doubt, call your vet.
Where does this list come from?
Each verdict comes from the ASPCA's toxic and non-toxic plant database (Animal Poison Control Center, USA), species by species, with a link to its entry. Species the ASPCA doesn't list are left out of both lists.
Not sure which plant you have?
Take a photo: we'll tell you the species, whether it's toxic to your pet and how to care for it.
