What this means for your dog
Dogs are not poisoned by holly fern — ASPCA lists Cyrtomium falcatum as non-toxic to dogs. The 'holly' in the name refers to the leaf shape, not the toxic Ilex hollies; this fern has no toxic principle reported, so a dog who shreds a frond is not at risk of poisoning, though large mouthfuls of fibrous leaf may cause mild stomach upset.

Questions about Holly Fern
Is Holly Fern toxic to dogs?
Holly Fern (Cyrtomium falcatum) is considered non-toxic to dogs. It is classified as generally safe, meaning it does not contain compounds expected to poison your dog.
What happens if my dog eats Holly Fern?
Most dogs that nibble Holly Fern will have no reaction at all. If your dog eats a large amount of the fibrous fronds, mild vomiting or diarrhea is possible simply from the bulk of plant material in the digestive tract.
How much Holly Fern would cause a problem for my dog?
Small nibbles are unlikely to cause any issue. Problems, if they occur at all, are associated with consuming significant quantities of the plant and are limited to temporary GI upset — not poisoning.
My dog ate a lot of Holly Fern and is still vomiting — should I call the vet?
Non-toxic does not mean unlimited quantities are harmless. If your dog consumed a large amount and is showing persistent vomiting or diarrhea that isn't resolving, contact your veterinarian — prolonged GI distress from any cause warrants a check-in.
