How much is okay?
Keep citrus bowls and brunch plates out of reach.
Rule of thumb: treats of all kinds should stay under ~10% of daily calories.
How to prepare them
- Do not feed segments, juice, or candied peel.
- Wash hands after handling peel if your dog licks skin.
- Pick up dropped citrus at breakfast before dogs scoop it.
Risks & exceptions
- Strong acidity can cause vomiting or mouth irritation.
- Peel oils may upset sensitive stomachs.
- Sugar-added grapefruit products add unnecessary calories.
Grapefruit is a skip—other fruits treat dogs more predictably.
If they ate too many
A larger portion or the wrong preparation is most likely to cause trouble.
- Drooling
- Soft stool
- Mild vomiting
Call your vet / pet poison line if:
- Repeated vomiting after citrus
- Refusal to eat with belly pain
