Can dogs eat lemons?

No — too acidic

No. Lemons are too acidic for dogs and the peel contains compounds that cause vomiting and digestive upset.

The full picture

Lemons are one citrus to avoid. Extreme acidity combined with peel essential oils (limonene, linalool) causes stomach upset, vomiting, and irritation. Most dogs avoid lemons instinctively, but some will eat lemon-flavoured yoghurt or discarded wedges. Lemon juice, lemon zest in baking, and lemony dressings are all off-limits. Limes have the same issues.
