My dog ate Rough-Shelled Macadamia — what to do

Step by step

  1. Take rough-shelled macadamia 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 a poison-control line — (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK. Both charge a consultation fee. 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 in the US, or Animal PoisonLine on 01202 509 000 in the UK.

My dog ate rough-shelled macadamia — FAQ

Is rough-shelled macadamia poisonous to dogs?

Yes — Rough-Shelled Macadamia (Macadamia tetraphylla) is regarded as toxic to dogs, based on genus- and family-level toxicity data. The ASPCA does not list Macadamia tetraphylla individually, but macadamia nuts are recognised by the ASPCA Animal Poison Control Center as toxic to dogs. Ingestion causes weakness, vomiting, tremors, hyperthermia, and hind-limb ataxia within about 12 hours. Treat this species and its nuts as dog-toxic; clear fallen nuts and consult a vet on ingestion.

How serious is it if my dog ate rough-shelled macadamia?

Rough-Shelled Macadamia is toxic to dogs and reactions can be significant, so treat any ingestion as urgent. Call your vet, or (888) 426-4435 in the US, or Animal PoisonLine on 01202 509 000 in the UK, 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. The ASPCA does not list Macadamia tetraphylla individually, but macadamia nuts are recognised by the ASPCA Animal Poison Control Center as toxic to dogs. Ingestion causes weakness, vomiting, tremors, hyperthermia, and hind-limb ataxia within about 12 hours. Treat this species and its nuts as dog-toxic; clear fallen nuts and consult a vet on ingestion.

How do I stop this happening again?
