Can dogs eat oranges, lemons and other citrus?
A segment of peeled orange is harmless. The peel, pith and seeds contain essential oils that irritate the gut, and most dogs dislike citrus anyway.
Signs to watch for
- drooling
- vomiting
- diarrhoea
- wobbliness if a lot of peel was eaten
What makes it harmful
Limonene, linalool and psoralens, concentrated in the peel
The essential oils in citrus peel are gastrointestinal irritants and, in quantity, can affect the central nervous system. The flesh contains far less. Lemons and limes are more irritating than oranges, and grapefruit is the most so.
How to prepare it
