Small plain seedless orange segments are safe for dogs in moderation. Cats should avoid citrus entirely — peel oils may irritate the stomach and nervous system. Skip peel, pith, juice concentrates, and sweetened orange products.
Oranges are citrus fruits with juicy segments and aromatic peel, eaten fresh, juiced, or used for zest in desserts and savory dishes. Varieties include navel, Valencia, mandarin, and clementine.
Orange flesh provides water, vitamin C, and natural sugars. Peel, pith, and citrus oils are more irritating than plain flesh.
Marmalades, candied peel, and juice concentrates are much more concentrated in sugar and citrus compounds than fresh segments. Zest and citrus extracts should stay away from pet dishes.
