Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
The fleshy segments of oranges are safe for dogs in moderation and provide vitamin C, potassium, and fibre. However, the peel, pith, and seeds should be removed — the peel contains oils that can irritate a dog's digestive system. The high citric acid content can cause stomach upset in some dogs, and the natural sugar means oranges should be a treat, not a staple. Start with a small piece to see how your dog tolerates it.
What You Should Know
While oranges is not outright toxic, there are important precautions to bear in mind before sharing it with your dog. Portion size matters, and certain preparations or varieties may be unsafe. If your dog has any existing health conditions, check with your vet first.
