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.
