Is Agave montana toxic to dogs?

Mildly. The ASPCA lists agave montana 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. Agave is not individually listed on the ASPCA toxic or non-toxic plant database. The genus contains calcium oxalate raphides and steroidal saponins, which can cause oral and gastrointestinal irritation (drooling, vomiting) if chewed and contact dermatitis from the sap. Treat as a caution plant around pets and consult a vet if ingestion occurs.

Agave is not individually listed on the ASPCA toxic or non-toxic plant database. The genus contains calcium oxalate raphides and steroidal saponins, which can cause oral and gastrointestinal irritation (drooling, vomiting) if chewed and contact dermatitis from the sap. Treat as a caution plant around pets and consult a vet 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 agave montana.

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: Agave montana is mildly toxic to cats as well. See the full agave montana pet-safety guide for both species.
