Is Mandarin orange toxic to dogs?

Citrus reticulata

Mildly toxic to dogs

Mildly. The ASPCA lists mandarin orange 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. Citrus reticulata (mandarin orange) contains the same toxic principles as other citrus species — essential oils and psoralens — concentrated in the peel, leaves, and stems. While the ASPCA's individual entry is for 'Orange' (Citrus sinensis), the genus-level rule applies: all Citrus are listed as toxic to dogs, cats, and horses (vomiting, diarrhoea, depression, potential dermatitis). Keep foliage and rind away from pets.

What to do if your dog ate mandarin orange

  1. Remove any plant material from your dog's mouth and move mandarin orange 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 mandarin orange to the appointment so it can be treated correctly.

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