Is Dimpled Trout Lily toxic to dogs?

Mildly. The ASPCA lists dimpled trout lily 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. Erythronium is not listed as a toxic genus by the ASPCA, which explicitly identifies it as a non-dangerous member of the lily family (unlike Lilium and Hemerocallis). No specific toxic principle documented; classified mildly-toxic rather than pet-safe as a precaution, as bulb contact may cause skin irritation.

Erythronium is not listed as a toxic genus by the ASPCA, which explicitly identifies it as a non-dangerous member of the lily family (unlike Lilium and Hemerocallis). No specific toxic principle documented; classified mildly-toxic rather than pet-safe as a precaution, as bulb contact may cause skin irritation. 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 dimpled trout lily.

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: Dimpled Trout Lily is mildly toxic to cats as well. See the full dimpled trout lily pet-safety guide for both species.
