Is Polypodium cambricum toxic to dogs?

Mildly. The ASPCA lists polypodium cambricum as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. Polypodium cambricum is not individually listed in the ASPCA Toxic and Non-Toxic Plants database. It is a true polypody fern with no recognised toxic principle, and ferns of this type are generally regarded as ASPCA non-toxic; nonetheless, because the species is not individually ASPCA-listed, treat it with caution and verify with a vet before assuming it is pet-safe.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to polypodium cambricum.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.

The ASPCA classification Growli uses applies to both cats and dogs: Polypodium cambricum is mildly toxic to cats as well. See the full polypodium cambricum pet-safety guide for both species.
