Is Mountain Bellwort toxic to dogs?

Mildly. The ASPCA lists mountain bellwort 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. Uvularia puberula is in the Colchicaceae family, the same family as the highly toxic autumn crocus (Colchicum autumnale). Although specific toxic alkaloid content has not been confirmed for U. puberula individually, the family membership warrants caution. The ASPCA does not list this species. In the absence of a confirmed non-toxic ASPCA listing, mildly-toxic classification is applied for cats and dogs.

Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to mountain bellwort.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. 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.

The ASPCA classification Growli uses applies to both cats and dogs: Mountain Bellwort is mildly toxic to cats as well. See the full mountain bellwort pet-safety guide for both species.
