Is Heart-leaved Homalomena toxic to dogs?

Yes — heart-leaved homalomena is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Homalomena belongs to the Araceae family and, like most aroids, contains calcium oxalate crystals. Ingestion causes oral irritation, drooling, and vomiting in cats and dogs. H. cordata is not individually listed by ASPCA, but based on family toxic principles (Araceae, calcium oxalate), it should be treated as toxic to pets and kept out of reach.

H. cordata is not individually listed by ASPCA, but based on family toxic principles (Araceae, calcium oxalate), it should be treated as toxic to pets and kept out of reach. 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 heart-leaved homalomena.

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: Heart-leaved Homalomena is toxic to cats as well. See the full heart-leaved homalomena pet-safety guide for both species.
