Dogs who ingest all or part of the hibiscus plant, will experience primarily gastrointestinal symptoms. These symptoms include loss of appetite, nausea, vomiting and diarrhea. Dogs can experience mild to severe symptoms. In extreme cases, the loss of bodily fluids can result in death, said Dr. William Buck, director of the National Animal Poison Control Center in the online magazine Housepet. Dogs with have severe or ongoing symptoms should visit their veterinarian for a diagnosis and treatment plan.
