The main thing to watch: acidity and peel oils irritate the stomach.
How to Serve Lemons Safely
No need to serve. Keep peels, wedges, and lemon desserts away; a licked drop of juice is not an emergency.
What If Your Dog Already Ate Lemons?
For most dogs, a small accidental taste is not an emergency. Watch for vomiting, diarrhea, or loss of appetite over the next 24 hours, keep fresh water available, and call your vet if symptoms appear — or sooner if your dog is very small, very young, or has existing health conditions.
