Is Pseuderanthemum carruthersii toxic to dogs?

Mildly. The ASPCA lists pseuderanthemum carruthersii 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. Pseuderanthemum carruthersii is not individually listed by the ASPCA. Although some Acanthaceae relatives are ASPCA non-toxic, that does not confirm this genus, so treat it as uncertain, prevent pets from chewing it, and verify with a vet before assuming it is safe.

Pseuderanthemum carruthersii is not individually listed by the ASPCA. Although some Acanthaceae relatives are ASPCA non-toxic, that does not confirm this genus, so treat it as uncertain, prevent pets from chewing it, and verify with a vet before assuming it is safe. 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 pseuderanthemum carruthersii.

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: Pseuderanthemum carruthersii is mildly toxic to cats as well. See the full pseuderanthemum carruthersii pet-safety guide for both species.
