Can dogs eat oranges?
Risky. A little flesh is not a poisoning risk, but the ASPCA notes citrus contains citric acid and essential oils that irritate.
How much is dangerous?
The ASPCA distinguishes small amounts from significant quantities without publishing a figure. The peel, pith, seeds and any essential oil product carry more of the irritants than the flesh does.
Why it does harm
Citric acid and essential oils cause gastrointestinal irritation. The ASPCA notes that the concentration matters: small amounts of the flesh are unlikely to cause more than an upset stomach, while significant quantities can cause central nervous system depression.

What to look for
- Vomiting or diarrhea

What to do

- Call a vet if a dog has eaten peel, a whole fruit, or any citrus essential oil product.
Common questions
Can dogs eat orange peel?
Best not. The ASPCA notes that the stems, leaves, peels, fruit and seeds of citrus plants all contain varying amounts of citric acid and essential oils that can cause irritation, and that only small amounts of the fruit itself are unlikely to cause more than a minor stomach upset.
Can dogs eat lemons or limes?
They are citrus too, so the same caution applies: the fruit, peel and seeds carry citric acid and essential oils, and the ASPCA warns that significant quantities can cause central nervous system depression as well as irritation.
