Can Dogs Eat Citrus Fruits (Oranges, Lemons, Limes)?

Verdict: CAUTION — a small piece of orange flesh is usually fine; peels, seeds and essential oils are not.

The stems, leaves, peels, fruit and seeds of citrus plants contain varying amounts of citric acid and essential oils. Small amounts of the fruit itself are unlikely to cause more than minor stomach upset — but the peel, seeds and oils can be irritating, and large amounts can cause depression or worse.

Why it's a caution

• Citric acid and essential oils can irritate the digestive tract: vomiting, diarrhea, drooling.
• The peel is the most concentrated part and is hard to digest — it can also cause blockage.
• Citrus essential oils are toxic to dogs, even through the skin.
• Some dogs just don't tolerate acid well.

Safe way to offer citrus

• Orange: peel it, remove all seeds and white pith, offer 1-2 segments max.
• Tangerines and mandarins: same rule, small pieces only.
• Lemons and limes: too sour and acidic — not worth it; one lick is fine, a whole fruit is not.
• Never feed the peel, seeds or any citrus essential oil.

How much is OK?

A couple of orange segments are plenty for a medium dog. Treats stay under 10% of daily calories. Watch for stomach upset the first time.
