Is Citrus toxic to dogs?
Citrus (Citrus spp.) is toxic to dogs. The agent is essential oils and psoralens.
ASPCA Animal Poison Control, 24 hours: (888) 426-4435 (a consultation fee may apply), or call your own vet. Take a piece of the plant with you.
Signs that need a vet the same day whatever the plant: repeated vomiting, drooling that will not stop, swelling of the mouth or face, trouble breathing or swallowing, collapse, or a seizure.
What it does, and why
Citrus contains essential oils and psoralens. The compound sits in the sap, so the plant does the most harm when it is broken — chewed, snapped, or pruned. Skin contact can irritate as well as ingestion.
Signs to watch for
Vomiting, diarrhea, depression; potential dermatitis. Fruit is edible, skins and plant material can cause problems.
ASPCA lists citrus species individually — Lemon, Lime, Orange, Grapefruit — all toxic on the same principles. This record is read from the Lemon entry (Citrus limonia).
How likely is it, really
Most cases are a chewed leaf rather than a meal. The dose matters: a nibble and a swallowed stem are different events. Volume, and how long ago, are the two things the vet will ask.
Keeping the plant anyway
Height alone does not work with a dog. What actually helps: a room the dog does not have unsupervised access to, a hanging position with no adjacent launch point, and clearing fallen leaves the same day, since a dropped leaf on the floor is the usual culprit. Dogs chew from boredom more than appetite — the fix is usually enrichment, not the plant.
Is it toxic to people?
No meaningful hazard to people from handling Citrus. Ordinary care with small children still applies — anything chewed in quantity can cause a stomach ache.
