Are Mass Cane Plants Toxic to Dogs?

Yes. The ASPCA lists mass cane (Dracaena fragrans 'Massangeana') as toxic to both dogs and cats. Several Dracaena species contain compounds that can cause vomiting, drooling, and weakness if ingested.

General Caution

No houseplant is completely "safe." Even non-toxic plants can cause stomach upset, skin irritation, or allergic reactions in sensitive pets or children. The best practice is to keep all plants out of reach of pets and young children.
