Is Salvinia molesta toxic to dogs?

Mildly. The ASPCA lists salvinia molesta 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. Salvinia molesta is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so its pet status is unconfirmed; treat with caution and verify with a vet. The larger hazard is regulatory and environmental — it is a federally and internationally prohibited noxious weed in many jurisdictions, and dense mats foul water that pets may drink.

Salvinia molesta is not individually listed on the ASPCA Toxic and Non-Toxic Plants database, so its pet status is unconfirmed; treat with caution and verify with a vet. The larger hazard is regulatory and environmental — it is a federally and internationally prohibited noxious weed in many jurisdictions, and dense mats foul water that pets may drink. 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 salvinia molesta.

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: Salvinia molesta is mildly toxic to cats as well. See the full salvinia molesta pet-safety guide for both species.
