My dog ate Sweet Flag — what to do

Step by step

  1. Take sweet flag away and remove any plant material from your dog's mouth so they cannot eat more.
  2. Note roughly how much was eaten and when — this helps the vet judge the risk.
  3. Do NOT induce vomiting unless a vet or poison-control specialist tells you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 (a consultation fee may apply) and follow their advice.
  5. Watch for drooling, pawing at the mouth, vomiting, loss of appetite, or lethargy, and bring a leaf or photo to the appointment.

This is general guidance, not veterinary advice. Pets vary, and a reaction may be to soil, fertiliser, or pesticide as well as the plant. When in doubt, call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435.

My dog ate sweet flag — FAQ

Is sweet flag poisonous to dogs?

Yes — the ASPCA lists Sweet Flag (Acorus calamus) as toxic to dogs. Acorus calamus is toxic to pets. The foliage and rhizome contain β-asarone (and related alkenylbenzenes), which is potentially carcinogenic and can cause vomiting and, in dogs, seizures on ingestion. While Acorus is not on the named ASPCA list, multiple toxicology sources document its toxic principle, so it should be kept away from cats, dogs and children; contact a vet if any part is eaten.

How serious is it if my dog ate sweet flag?

Sweet Flag is toxic to dogs and reactions can be significant, so treat any ingestion as urgent. Call your vet or poison control on (888) 426-4435 straight away rather than waiting to see if symptoms develop.

What symptoms should I watch for?

Signs usually appear soon after chewing: drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy. Acorus calamus is toxic to pets. The foliage and rhizome contain β-asarone (and related alkenylbenzenes), which is potentially carcinogenic and can cause vomiting and, in dogs, seizures on ingestion. While Acorus is not on the named ASPCA list, multiple toxicology sources document its toxic principle, so it should be kept away from cats, dogs and children; contact a vet if any part is eaten. Any worsening or persistent symptoms warrant an immediate vet visit.

Should I make my dog vomit?

No — do not induce vomiting unless a vet or the ASPCA Animal Poison Control Center specifically tells you to. The wrong action can make things worse. Call (888) 426-4435 and follow professional advice.

How do I stop this happening again?

Keep sweet flag well out of reach, or swap it for an ASPCA non-toxic plant — see the best dogs-safe plants list.
