SAFE

Monitor for stomach upset if leaves are chewed.

When to contact a vet: Contact a vet if symptoms persist.

Symptoms to look for

  • vomiting
  • diarrhoea if large amount eaten

Why

Boston ferns are listed as non-toxic to dogs by the ASPCA. They are a popular pet-safe houseplant. If a dog eats a large amount of leaves, mild vomiting or diarrhoea is possible simply from the fibre, but serious toxicity is not expected.
