Is Passiflora alata toxic to dogs?

Mildly. The ASPCA lists passiflora alata 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. Passiflora is not individually listed on the ASPCA toxic/non-toxic plant database, so its pet status is unconfirmed. As with other passionflowers, the leaves, stems and unripe fruit contain cyanogenic glycosides capable of releasing cyanide if eaten in quantity. Treat as a caution plant: keep pets from the foliage and green fruit, and verify with a vet if ingestion is suspected.

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 passiflora alata.

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: Passiflora alata is mildly toxic to cats as well. See the full passiflora alata pet-safety guide for both species.
