Is Mandevilla Toxic to Dogs?

Yes — Mandevilla is mildly toxic to dogs

Mandevilla is a tropical vine with large trumpet-shaped flowers. While it belongs to the Apocynaceae family (same as highly toxic Oleander), Mandevilla is significantly less toxic. It causes mild GI upset rather than the cardiac effects of its relatives.
