Yellow: with caution
Yes, but only a few pieces of flesh. Although the ASPCA lists the orange plant as toxic to dogs, it explains that the fruit is edible, while the peel and plant parts can cause problems.
Why oranges are marked yellow
According to the ASPCA, citrus stems, leaves, peel, fruit and seeds contain varying amounts of citric acid and essential oils. In larger amounts, they cause irritation and lethargy. If a dog eats just a little flesh, usually no more than a mild stomach upset is expected. The ASPCA lists vomiting, diarrhoea and lethargy as signs associated with oranges.
What to watch for
- Peel completely: The peel is tough and hard to digest. According to the American Kennel Club, it can obstruct the intestines.
- Remove the seeds: Take out the seeds before sharing.
- Segments only: One or two small pieces are enough. Otherwise, the acid and fruit sugar can upset the stomach.
- Not every dog likes it: Some dogs dislike the citrus smell. There is no need to make your dog eat it.
- Count it in: Oranges also contain fruit sugar and count towards the daily treat allowance.
What if your dog has eaten peel?
A few scraps of peel usually cause only stomach rumbling. Monitor your dog and offer water. If your dog has taken a lot of peel from the bin, vomits repeatedly, seems lethargic or cannot pass stools, call your vet.
If you suspect poisoning, take your dog to a vet or an emergency veterinary service immediately.
