Is Sea Holly toxic to dogs?
Eryngium planum
Mildly. The ASPCA lists sea holly as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Eryngium is not individually listed on the ASPCA Toxic/Non-Toxic Plants database, so its status is uncertain; treat with caution and verify with a vet. It is not known to be seriously poisonous, and its very spiny foliage and flower heads act as a strong physical deterrent to nibbling pets.
What to do if your dog ate sea holly
- Remove any plant material from your dog's mouth and move sea holly out of reach.
- Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
- Do not induce vomiting unless a vet or poison-control specialist instructs you to.
- Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
- Bring a leaf or photo of sea holly to the appointment so it can be treated correctly.
General guidance, not veterinary advice. If you think your dog has eaten sea holly, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
