Can dogs eat lemon?

Toxic — do not feed
No, dogs should not eat lemons.

Why

While the flesh of a lemon is not strongly poisonous, lemons are highly acidic and the juice, rind, and aromatic oils are problematic for dogs. Concentrated citric acid can cause digestive upset, the rind contains psoralen and can cause intestinal obstruction if swallowed, and the essential oils are considered toxic. Most dogs naturally avoid the sour citrus taste.

Warning signs to watch for

Drooling, vomiting, diarrhea, and digestive upset; large amounts of rind can cause intestinal obstruction.
