Is Autumn Fern 'Brilliance' toxic to dogs?

Dryopteris erythrosora 'Brilliance'

Mildly toxic to dogs

Mildly. The ASPCA lists autumn fern 'brilliance' 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. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Dryopteris is not on the ASPCA non-toxic list, and the genus contains filicic acid (filixic acid / filicin) and thiaminase in its rhizomes, compounds documented to cause poisoning in grazing livestock. It is not individually evaluated by the ASPCA for cats and dogs; treat as mildly toxic, keep pets from chewing it, and verify with a vet if ingestion is suspected.
