Is Filbert 'Barcelona' toxic to dogs?

No — filbert 'barcelona' is listed by the ASPCA as non-toxic to dogs. It is a sensible choice for a home with a dog; a curious nibble will not poison them, though no plant is meant to be eaten. ASPCA does not list hazel/filbert (Corylus) foliage as toxic, and the genus is absent from its toxic plant lists, so the plant is treated as non-toxic to cats and dogs. The risk lies in the nuts: whole hazelnuts can choke or obstruct the gut, are high in fat (pancreatitis risk in dogs), and moldy fallen nuts may carry tremorgenic mycotoxins, so remove dropped nuts.

Yes — the ASPCA lists filbert 'barcelona' as non-toxic to dogs and dogs. A dog that chews a large amount of any foliage can still get a mild, brief stomach upset, so discourage grazing, but it will not be poisoned.

The ASPCA classification Growli uses applies to both cats and dogs: Filbert 'Barcelona' is non-toxic to cats as well. See the full filbert 'barcelona' pet-safety guide for both species.
