Is Longan toxic to dogs?

Dimocarpus longan

Mildly toxic to dogs

Mildly. The ASPCA lists longan 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. Longan is not individually listed by the ASPCA, so treat it with caution and verify with a vet. As a member of the soapberry family (Sapindaceae), its seeds and shells contain saponins and hypoglycin-type compounds and should be kept away from pets. Ripe flesh is widely eaten, but never let animals access the seeds or rinds.

What to do if your dog ate longan

  1. Remove any plant material from your dog's mouth and move longan out of reach.
  2. Note how much was eaten and when, and watch for drooling, vomiting, or lethargy.
  3. Do not induce vomiting unless a vet or poison-control specialist instructs you to.
  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
  5. Bring a leaf or photo of longan to the appointment so it can be treated correctly.

General guidance, not veterinary advice. If you think your dog has eaten longan, contact your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 — do not wait for symptoms to worsen.
