Is Black-eyed Susan vine toxic to dogs?

Thunbergia alata

Mildly toxic to dogs

Mildly. The ASPCA lists black-eyed susan vine 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. This classification follows the ASPCA Toxic and Non-Toxic Plant List. Thunbergia alata is not individually listed on the ASPCA toxic or non-toxic plant database, and no Thunbergia species appears on it, so the genus cannot be confirmed safe. Some pet-toxicity references note possible mild gastrointestinal upset if chewed; treat as mildly toxic and verify with your vet before assuming it is pet-safe. Note this is the vine, not the unrelated Rudbeckia hirta also called black-eyed Susan.

What to do if your dog ate black-eyed susan vine

  1. Remove any plant material from your dog's mouth and move black-eyed susan vine out of reach.

  4. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice.
