Hosta, also known as funkia or plantain lily, grows in many yards. This plant thrives in areas of dense shade. Hosta is dangerous if eaten by dogs because it is poisonous.
Hosta is a member of the Liliaceae family and has chemicals called saponins that make it toxic to dogs, states the American Society for the Prevention of Cruelty to Animals. Ingesting all or part of the hosta plant causes mild to severe adverse health effects in dogs.
According to Vet Info.com, ingesting the hosta plant causes dogs to suffer from depression, diarrhoea and vomiting. Take dogs with severe or ongoing symptoms to their veterinarian for a diagnosis and treatment plan.
Prevent your dog from accidental plant ingestion by placing a fence around the poisonous plants in your yard. If you have extremely curious dogs or puppies, the best way to prevent accidental plant ingestion is to remove the poisonous plants completely.
