Is Sagittaria sagittifolia toxic to dogs?

Mildly. The ASPCA lists sagittaria sagittifolia 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. Sagittaria sagittifolia is not individually listed by the ASPCA as toxic or non-toxic to pets. Cultivated tubers are eaten in Asia after cooking, but the raw plant is acrid and not established as pet-safe; treat with caution around cats and dogs and verify with a vet before assuming it is safe.

Sagittaria sagittifolia is not individually listed by the ASPCA as toxic or non-toxic to pets. Cultivated tubers are eaten in Asia after cooking, but the raw plant is acrid and not established as pet-safe; treat with caution around cats and dogs and verify with a vet before assuming it is safe. 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 sagittaria sagittifolia.

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: Sagittaria sagittifolia is mildly toxic to cats as well. See the full sagittaria sagittifolia pet-safety guide for both species.
