NO! Lemons and limes can be toxic to your dog!
This is because the skins of lemons and limes contain a substance called psoralen, which can cause dogs to have gastrointestinal symptoms like vomiting and diarrhea .
If very large amounts of psoralen are consumed by dogs, more severe symptoms, such as muscle tremors, difficulty walking, liver failure and death, can result.
