Hostas & Dogs

Hostas come in many shapes and sizes, producing vibrant green leaves that can be streaked with color. These plants are not just enticing to humans, however. Curious canines can and will on occasion investigate hostas, which may lead to problems.

  1. Identification

    • The hosta plant, or Hosta plataginea, is a member of the lily family. The leaves are typically green but can appear blue in color. Leaves may be streaked with whites or yellow. Some hostas produce flowers in addition to their leaves.

    Considerations

    • The American Society for the Prevention of Cruelty to Animals (ASPCA) Poison Control Center lists hostas as toxic to dogs, if ingested.

    Effects

    • Hostas can cause mild gastrointestinal effects including nausea, vomiting, diarrhea and loss of appetite. Depression and lethargy may also occur. Fatal side effects are rare, but may still occur if a large amount of hostas are eaten.

    Active Toxins

    • The active toxins that cause symptoms in dogs when ingested are known as saponins. These chemicals cause a foamy build-up of gas within the dog's stomach.

    Solution

    • Keep your dog away from hosta plants. Supervise her when she is around the plants to ensure she does not eat them. In case of accidental ingestion, speak to a licensed veterinary medical care professional.
