Is Micranthemum tweediei 'Monte Carlo' toxic to dogs?

Mildly. The ASPCA lists micranthemum tweediei 'monte carlo' 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. Micranthemum tweediei is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its pet status is not formally established; treat as uncertain and verify with a vet before assuming it is safe to ingest. No specific toxic principle is documented, but absence of an ASPCA listing is not a safety guarantee.

Micranthemum tweediei is not individually listed in the ASPCA Toxic and Non-Toxic Plants database, so its pet status is not formally established; treat as uncertain and verify with a vet before assuming it is safe to ingest. No specific toxic principle is documented, but absence of an ASPCA listing is not a safety guarantee. 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 micranthemum tweediei 'monte carlo'.

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.
