Is Autumn Cascades Tupelo toxic to dogs?

Mildly. The ASPCA lists autumn cascades tupelo 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. Nyssa sylvatica is not individually listed by ASPCA as toxic. The small blue-black drupes may cause mild gastrointestinal upset if ingested in quantity by pets. The berries are a valuable wildlife food source for birds but are not recommended for pet or human consumption. Exercise caution with pets that tend to eat fallen berries.

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.
