Is Sweet Betsy toxic to dogs?

Mildly. The ASPCA lists sweet betsy 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. Trillium cuneatum is not individually listed by the ASPCA. NC State Extension classifies it as low-severity poisonous: fruits and roots are the potentially problematic parts, with the toxic principle unconfirmed. As with related Trillium species, steroidal saponins may be present. Keep pets and children from ingesting any part; contact a vet or poison control if ingestion occurs.

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 sweet betsy.

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: Sweet Betsy is mildly toxic to cats as well. See the full sweet betsy pet-safety guide for both species.
