Is Creeping Mazus toxic to dogs?

Mildly. The ASPCA lists creeping mazus 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. Mazus reptans is not individually listed by ASPCA in their toxic or non-toxic plant database. No documented toxic principles are known for this genus. However, as the species is not ASPCA-cleared, caution is appropriate: keep monitoring pets that chew plants and consult a vet if significant ingestion occurs.

Mazus reptans is not individually listed by ASPCA in their toxic or non-toxic plant database. No documented toxic principles are known for this genus. However, as the species is not ASPCA-cleared, caution is appropriate: keep monitoring pets that chew plants and consult a vet if significant 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 creeping mazus.

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: Creeping Mazus is mildly toxic to cats as well. See the full creeping mazus pet-safety guide for both species.
