Plain-English summary
A dog became very sick after its owner applied pennyroyal oil, a flea treatment bought at a health food store. Within two hours, the dog started vomiting, and despite emergency care, it sadly passed away within 48 hours. A necropsy (animal autopsy) revealed that the pennyroyal oil was the cause of death. This case highlights the dangers of using certain essential oils on pets without veterinary guidance.
