Safety status
What this means for your dog
Dogs that chew grapefruit pulp, peel, or seeds can develop GI upset from the essential oils and psoralens concentrated in the plant. ASPCA classifies grapefruit as toxic; the rind and seeds carry the most potent dose, and most reactions stay mild as long as a small amount was eaten.
What to watch for
Vomiting, diarrhea, depression, drooling, and loss of appetite are most common. After contact with rind or essential oil, watch for skin irritation that can worsen in sunlight (psoralen-driven photosensitivity).
Time window
Signs typically appear within hours of ingestion; ASPCA does not publish a specific recovery duration.
When to call the vet
Call your vet or ASPCA Poison Control if vomiting doesn't resolve, your dog refuses food, becomes notably lethargic, or develops skin redness after exposure to grapefruit oil or peel.
