Caution
Can dogs eat citrus fruits and peels? Caution
Caution. A bite of citrus fruit usually causes only mild stomach upset, but peels, seeds and plant parts contain oils that irritate dogs.
What to do now
- Remove any remaining peels, fruit or plant parts.
- Watch for vomiting, diarrhea or unusual tiredness.
- Call your vet if your dog ate a lot of peel or plant material, or vomits repeatedly.
Don't
- Don't make your dog vomit unless a vet tells you to.
How to give it safely
Avoid lemons and limes. If you share orange, give only small pieces of peeled, seedless flesh.
Signs to watch for
- Vomiting
- Diarrhea
- Depression or low energy
- Skin irritation
Why
Citrus stems, leaves, peels and seeds contain citric acid and essential oils, and lemons also contain psoralens. Larger amounts can cause vomiting, diarrhea and depression.
