Can Dogs Eat Grapefruit?
Why it’s a problem
Grapefruit is the most problematic common citrus for dogs: the flesh is strongly acidic, and the peel, pith and leaves contain furanocoumarins — the same psoralen family that makes lemons and limes risky — which irritate the stomach and can affect the nervous system in larger doses.
How to serve it safely
Keep grapefruit, grapefruit juice and grapefruit trees away from dogs. There is no amount worth offering.
Warning signs to watch for
Drooling, vomiting, diarrhea, weakness, tremors and unusual sensitivity to light after eating peel, pith or large amounts of flesh.
When to call the vet
Call your vet or a poison hotline if your dog eats grapefruit peel or leaves, or several whole fruits — furanocoumarin exposure warrants guidance.
Common questions
Is a lick of grapefruit juice harmful?
A lick will cause a grimace and maybe mild drooling at worst. The danger is peel, leaves and quantity.
Does grapefruit interact with my dog’s medication?
Furanocoumarins interfere with drug metabolism in many species. Never give grapefruit to a medicated dog without asking your vet.
